How To Wirte A Function In Python

Mutable objects are these which may be modified after creation. In Python, dictionaries are examples of mutable objects. Passing mutable lists or dictionaries as default arguments to a operate can have unexpected effects.

Programmer who use lists or dictionaries as default arguments to a function, count on this system to create a brand new listing or dictionary each time that the operate is called. Default values can not be created when a operate is called. Default values are created precisely once, when the operate is defined, i.e. at compile-time. The physique of a operate is just a Python script. When the operate is called, its arguments are exceeded as parts of the listing args; named arguments are additionally exceeded as atypical variables to the Python script.

The result's returned from the Python code within the standard way, with return or yield (in case of a result-set statement). If you don't supply a return value, Python returns the default None. Functions supply tremendously critical performance to programs, permitting duties to be outlined as soon as and carried out repeatedly with totally distinct data. The primary process above makes use of three totally distinct units of precise parameters within the three calls to sumProblem. The operate has two parameters, that are referred to as x and y. This signifies that the operate f is anticipating two values, or I need to say "two objects".

This signifies that a goes to x and the results of 2+a 'goes to' the variable y. The mechanism for assigning arguments to parameters is known as argument passing. When we attain the return statement, the item referenced by z can be return, which suggests that it'll be assigned to the variable res1. After leaving the perform f, the variable z and the parameters x and y can be deleted automatically.

As we know, features are the block of statements used to carry out some precise duties in programming. It additionally helps to interrupt the massive group of code into smaller chunks or modules. Functions might possibly be referred to as anyplace and the variety of occasions in a program. It permits us to reuse the code by merely calling the actual carry out or block in a program. We can outline features contained in the class, modules, nested functions, etc. It is feasible to outline a carry out to accept a variety of parameters and use them for processing contained in the carry out block.

Parameters/arguments could also be given acceptable formal names. The greet() operate is now outlined to be given a string parameter referred to as name. Inside the function, the print() declaration is modified to monitor the greeting message addressed to the acquired parameter. Within the operate definition statement, username and followers are contained within the parentheses of the profile_info() function.

The block of the function prints out details concerning the consumer as strings, making use of the 2 parameters. Here, f is a function that operates on the inputs x and y. However, programming features are rather extra generalized and versatile than this mathematical definition.

Because it treats similar to the object, and it has the identical properties and process as an object. A perform would be assigned to a variable, move them as an argument, retailer them in information buildings and return a worth from different functions. It would be manipulated, resembling different objects in Python. Furthermore, all of the info within the Python program is represented within the objects or relations. Hence it's additionally referred to as first-class residents of Python function. Idempotent features are straightforward to check considering they're assured to continuously return the identical end result when referred to as with the identical arguments.

Testing is just a matter of checking that the worth returned by numerous completely diverse calls to the perform return the envisioned value. What's more, these checks will probably be fast, a crucial and sometimes ignored challenge in Unit Testing. And refactoring when coping with idempotent features is a breeze. No matter the method you modify your code outdoors the function, the results of calling it with the identical arguments will normally be the same. This was an introduction on tips on easy methods to create straight forward features and the method to cross facts into them, with parameters. We additionally went over the several sorts of arguments like positional, keyword, and default arguments.

With positional arguments, capabilities are referred to as with simply the values exceeded within the perform call. There, every worth immediately corresponds with the number, order, and situation of every parameter within the perform definition. It is usually envisioned that a perform name creates new objects for default values. Default values are created precisely once, when the perform is defined. If that object is changed, simply like the dictionary on this example, subsequent calls to the perform will check with this modified object. Python capabilities can return a quantity of return values, in contrast to C or C++, which you'll be capable to then use to set your output variables.

Variables would be exceeded as parameters to a function. The string f3 consists of a two-line operate definition of our unique operate f. You then concatenate this string with a brand new line to print the results of operating this newly created operate in your script by passing arbitrary arguments into it. Defining a brand new operate doesn't make the operate run.

Python's options have quite a great deallots of "wait I did not know that" features. Functions can outline default argument values, options would be referred to as with key phrase arguments, and options would be written to simply settle for any variety of arguments. Not all options are created equal in Python, however not all are created equally.

Python is a programming language with a main approach to abstraction and encapsulation. What makes a "good" Python operate differentiates a operate from a crappy one? You'd be shocked at what percentage definitions of "good" one can use. A operate is sensibly named if it may possibly tick off a lot of the gadgets on this guidelines If you comply with these rules, your code will probably be so gorgeous it'll make unicorns weep.

Parameters are arguments which might be routinely outlined as variables inside operate definitions. They might possibly be assigned values if you run the method, passing the arguments into the function. Note that vacant parentheses are normally required in equally a operate definition and a operate call, even when there are not any parameters or arguments. Execution proceeds to f() and the statements within the physique of f() are executed.

The execution error message mentions "global name". Names outlined outdoors any perform definition, on the "top-level" of your program are referred to as global. The lambda key-phrase creates an nameless function.

The xis a parameter that's exceeded to the lambda function. The code subsequent to the colon is the expression that's executed, when the lambda perform is called. The lambda perform is assigned to the z variable. In the above example, I even have used the definition of main(), which comprises this system logic I desire to run.

I've additionally outlined a operate referred to as 'demo', to incorporate a bit of code, that may be reused as and when necessary. Furthermore, I even have modified the conditional block, such that, it executes main(). Note the return declaration on the top of the operate definition. In our earlier examples, we have been applying the print() operate that allowed us to see the output of every function. But in most cases, you only want the operate to return a sure value, not inevitably print it out. Refactoring is a few factor you almost certainly do all of the time, even when the time period isn't acquainted to you.

It merely means altering a program's shape with out altering its behavior. So extracting a couple of strains of code from an extended perform and turning them right into a perform of their very very own is a style of refactoring. It's additionally occurs to be the quickest and commonest strategy to shorten an extended perform in a productive way.

And since you're giving all these new features proper names, the ensuing code reads method extra easily. I might write a complete publication on refactoring (in verifiable truth it's been finished many times) and won't go into specifics here. Just know that when you've got a perform that's too long, the best option to repair it can be thru refactoring. Parameters are names outlined in a perform definition, and arguments are the real values exceeded that perform call. A user-defined perform can be made to return a worth to the calling atmosphere by placing an expression in entrance of the return statement. In this case, the returned worth needs to be assigned to some variable.

The first assertion is a docstring that mentions what this operate does. The second like is a print procedure that shows the required string to the console. In a brand new textual content file referred to as square.py, we'll create a program that squares the parameter x and returns the variable y. We situation a identify to print the end result variable, which is shaped by operating the square() operate with three handed into it. The names() operate we outlined above units up a conditional assertion and a for loop, displaying how code may be organized inside a operate definition. Python promotes using docstrings for documenting functions.

The commonplace module referred to as json can take Python files hierarchies, and convert them to string representations; this course of known as serializing. Reconstructing the info from the string illustration known as deserializing. This strategy is particularly valuable if most of the imports are pointless counting on how this system executes. You could additionally wish to maneuver imports right into a perform if the modules are solely ever utilized in that function.

Even if the module identify has gone out of scope, the module is perhaps out there in sys.modules. When a docstring is defined, the Python interpreter assigns it to a extraordinary attribute of the perform referred to as __doc__. The first perform prints the module documentation string. If a funciton doesn't return a value, it implicitly returns None.

The __doc__and __file__ are uncommon state attributes. Note that there are two underscores on each edge of the attribute. It signifies that features have equal standing with different objects in Python.

Functions should be assigned to variables, saved in collections, or handed as arguments. This brings further flexibility to the language. You create a lambda perform and assign the brand new perform object to the variable f2. This variable can now be used like each different perform identify outlined in a daily perform definition. In Python, it isn't essential to outline the primary perform each time you write a program. This is since the Python interpreter executes from the highest of the file until a selected perform is defined.

Hence, having an outlined commence line for the execution of your Python program is beneficial to raised perceive how your program works. Python is likely among the preferred programming languages to learn. The primary operate in Python acts because the purpose of execution for any program. Another significant factor about python function, you could cross (string, number, list, dictionary etc.) as argument/parameter inside python function.

There are principally 2 varieties of features in Python. The perform created by the consumer is named the user-defined perform and the perform presented by Python is named the build-in function. Variables created inside a perform definition are local; you can't entry a neighborhood variable from outdoors its dwelling function. That means you're free to have a number of variables with the identical identify so lengthy as they don't seem to be within the identical function. Step 4) Functions in Python are themselves an object, and an object has some value. When you run the command "print square" it returns the worth of the object.

Since we haven't exceeded any argument, we don't have any designated operate to run over right here it returns a default worth which is the situation of the object. In sensible Python program, you almost certainly won't ever must do this. That's when the return fact comes into play. Use the return key phrase to specify the return value, which might be nearly any Python object (e.g., integer, string, list, tuple, dictionary, set, etc.). Lambda Function, additionally known as 'Anonymous function' is identical as a daily python operate however will be outlined with no name.

While natural capabilities are outlined making use of the def keyword, nameless capabilities are outlined making use of the lambda keyword. … They can absorb mutliple parameters as in common functions. A Python operate can return solely a single worth b. Python operate doesn't return some factor till and till you add a return assertion c. A operate can take a vast variety of arguments, d.

A perform is a block of code which solely runs when it can be called. You can move data, which is referred to as parameters, right into a function. Function blocks start with the key phrase def observed by the perform identify and parentheses ( ). Any enter parameters or arguments ought to be positioned inside these parentheses. You additionally can outline parameters inside these parentheses. While defining a function, its parameters might be assigned default values.

This default worth will get substituted if an acceptable genuine argument is handed when the perform is called. However, if the genuine argument shouldn't be provided, the default worth shall be used contained in the function. Then we now have a set of opening and shutting parentheses, (). Inside them, there should be zero, one, or extra optionally available comma separated parameters with their optionally available default values. Annotations don't impose any semantic restrictions on the code whatsoever. They're purely bits of metadata hooked up to the Python perform parameters and return value.

Is It Easy To Lose 3Kg

The primary goals of behavioral strategies for weight control are to increase physical activity and to reduce caloric intake by altering eating habits (Brownell and Kramer, 1994; Wilson, 1995). A subcategory of behavior modification, environmental management, is discussed in the next section. Behavioral treatment, which was introduced in the 1960s, may be provided to a single individual or to groups of clients.

Typically, individuals participate in 12 to 20 weekly sessions that last from 1 to 2 hours each , with a goal of weight loss in the range of 1 to 2 lb/wk . In the past, behavioral approaches were applied as stand-alone treatments to simply modify eating habits and reduce caloric intake. However, the long-term effectiveness of these diets is somewhat limited. Approximately 40 to 50 percent of patients drop out of the program before achieving their weight-loss goals. In addition, relatively few people who lose large amounts of weight using VLCDs are able to sustain the weight loss when they resume normal eating. In two studies, only 30 percent of patients who reached their goal were able to maintain their weight loss for at least 18 months.

Within 1 year, the majority of patients regained approximately two-thirds of the lost weight (Apfelbaum et al., 1987; Kanders and Blackburn, 1994). In a more recent study with longer followup, the average regain over the first 3 years of follow-up was 73 percent. However, weight tended to stabilize over the fourth year. At 5 years, the dieters had maintained an average of 23 percent of their initial weight loss. At 7 years, 25 percent of the dieters were maintaining a weight loss of 10 percent of their initial body weight (Anderson et al., 1999, 2001). Increased physical activity is an essential component of a comprehensive weight-reduction strategy for overweight adults who are otherwise healthy.

Is It Possible To Lose 3Kg In 2 Weeks The availability of exercise facilities at military bases can reinforce exercise and fitness programs that are necessary to meet the services' physical readiness needs generally, and for weight management specifically. For a given individual, the intensity, duration, frequency, and type of physical activity will depend on existing medical conditions, degree of previous activity, physical limitations, and individual preferences. Referral for additional professional evaluation may be appropriate, especially for individuals with more than one of the above extenuating factors. The benefits of physical activity (see Table 4-1) are significant and occur even in the absence of weight loss (Blair, 1993; Kesaniemi et al., 2001). It has been shown that one of the benefits, an increase in high-density lipoproteins, can be achieved with a threshold level of aerobic exercise of 10 to 11 hours per month.

The largest amount of weight loss occurred early in the studies (Ditschuneit et al., 1999; Heber et al., 1994). One study found that women lost more weight between the third and sixth months of the plan, but men lost most of their weight by the third month (Heber et al., 1994). All of the studies resulted in maintenance of significant weight loss after 2 to 5 years of follow-up.

Hill's review of Rothacker pointed out that the group receiving meal replacements maintained a small, yet significant, weight loss over the 5-year program, whereas the control group gained a significant amount of weight. Active intervention, which included dietary counseling and behavior modification, was more effective in weight maintenance when meal replacements were part of the diet (Ashley et al., 2001). Meal replacements were also found to improve food patterns, including nutrient distribution, intake of micronutrients, and maintenance of fruit and vegetable intake.

Very-low-calorie diets were used extensively for weight loss in the 1970s and 1980s, but have fallen into disfavor in recent years (Atkinson, 1989; Bray, 1992a; Fisler and Drenick, 1987). FDA and the National Institutes of Health define a VLCD as a diet that provides 800 kcal/day or less. Since this does not take into account body size, a more scientific definition is a diet that provides 10 to 12 kcal/kg of "desirable" body weight/day .

The primary goal of VLCDs is to produce relatively rapid weight loss without substantial loss in lean body mass. To achieve this goal, VLCDs usually provide 1.2 to 1.5 g of protein/kg of desirable body weight in the formula or as fish, lean meat, or fowl. Fisler and Drenick reviewed the literature and concluded that about 70 g/day of protein is needed to ensure that nitrogen balance is achieved within a short period of time on a VLCD. For previously sedentary individuals, a slow progression in physical activity has been recommended so that 30 minutes of exercise daily is achieved after several weeks of gradual build-up. This may also apply to some military personnel, especially new recruits or reservists recalled to active duty who may be entering service from previously very sedentary lifestyles.

The activity goal has been expressed as an increase in energy expenditure of 1,000 kcal/wk (Jakicic et al., 1999; Pate et al., 1995), although this quantity may be insufficient to prevent weight regain. For that purpose, a weekly goal of 2,000 to 3,000 kcal of added activity may be necessary (Klem et al., 1997; Schoeller et al., 1997). Thus, mental preparation for the amount of activity necessary to maintain weight loss must begin while losing weight . Success in the promotion of weight loss can sometimes be achieved with the use of drugs. Almost all prescription drugs in current use cause weight loss by suppressing appetite or enhancing satiety. One drug, however, promotes weight loss by inhibiting fat digestion.

To sustain weight loss, these drugs must be taken on a continuing basis; when their use is discontinued, some or all of the lost weight is typically regained. Therefore, when drugs are effective, it is expected that their use will continue indefinitely. For maximum benefit and safety, the use of weight-loss drugs should occur only in the context of a comprehensive weight-loss program. In general, these drugs can induce a 5- to 10-percent mean drop in body weight within 6 months of treatment initiation, but the effect can be larger or smaller depending on the individual. As with any drug, the occurrence of side effects may exclude their use in certain occupational contexts.

The most important component of an effective weight-management program must be the prevention of unwanted weight gain from excess body fat. The military is in a unique position to address prevention from the first day of an individual's military career. There is significant evidence that losing excess body fat is difficult for most individuals and the risk of regaining lost weight is high. From the first day of initial entry training, an understanding of the fundamental causes of excess weight gain must be communicated to each individual, along with a strategy for maintaining a healthy body weight as a way of life.

A nutritionally balanced, hypocaloric diet has been the recommendation of most dietitians who are counseling patients who wish to lose weight. This type of diet is composed of the types of foods a patient usually eats, but in lower quantities. There are a number of reasons such diets are appealing, but the main reason is that the recommendation is simple—individuals need only to follow the U.S. In using the Pyramid, however, it is important to emphasize the portion sizes used to establish the recommended number of servings. For example, a majority of consumers do not realize that a portion of bread is a single slice or that a portion of meat is only 3 oz. Whether you have a special occasion coming up or you just want to feel healthier, sometimes you might want to lose weight fast.

Losing 5 kilograms in one week is a difficult goal to reach, but you may be able to do it with the right diet and exercise strategies. However, losing weight slowly will make it easier to maintain your weight loss. Research has shown that eating a low-carb diet can help you lose weight fast. In fact, a short-term decrease in carb intake may help reduce water weight and bloating. Hence, many people go low-carb when trying to slim down. Eating plenty of protein, particularly lean protein sources, is linked to increased metabolism and decreased appetite, which may effectively aid weight loss.

The efficacy of individual interventions is poor, and evidence regarding the efficacy of combinations of strategies is sparse, with results varying from one study to another and with the individual. Recent studies that have focused on identifying and studying individuals who have been successful at weight management have identified some common techniques. These include self-monitoring, contact with and support from others, regular physical activity, development of problem-solving skills , and relapse-prevention/limitation skills. Next is your diet, a healthy ballanced diet is not a weight loss diet. It becomes a weight loss diet when you also reduced the calorie intake of that diet to less then what you burn inorder to lose wight every day constantly over a 7 day period.

Firstly, I would recommend you speak to your GP; there are some conditions such as Thyroid disorders that can make it very difficult to shed the kilos, even when we are exercising and eating well. Secondly, I would start a diet diary, recording everything you eat for a week and the time of your meals. When analyzing a diet diary we look at what foods you are eating at different times of the day, the volume of food consumed and importantly the amount of meals you are consuming in a given day. The best meal plan for weightloss involves a diet of 6 small meals a day, spaced out in two hour increments. There is plenty of information regarding what foods you should eat and those to be avoided but ensure that you are consuming enough fresh fruit and vegetables to fulfil daily requirements or you will begin to feel fatigued. Try looking up the "raw food pyramid" as it is a good indication of the food you should eat.

Include proteins at every meal, but only a serve that is smaller than your palm. Australian Dietary guidelines as well as WW's program guidelines, recommend a safe weight loss rate of 500g-1 kg a week. You may lose more in the first few weeks, but this should even out over time.

Losing weight too quickly isn't good for your health, and can actually make it harder for you to sustain the weight loss long term. Losing weight too quickly can also pose a risk to your overall health including developing gall stones, irregular heart beat and excessive loss of lean muscle mass. Following a 'quick-fix' approach to weight loss also doesn't help you work on the root cause of your weight gain in the first place. Weight loss isn't just about what you eat and the activity you do – it's about your mindset and the way you think too. Shifting your mindset takes time, that's why a slow and steady approach will turn about to be the most effective in the long run. Another common reason for a weight plateau is being less diligent with your eating and activity behaviours.

Often when we start a weight loss program we're highly motivated, following the program religiously, tracking everything we eat and moving more each day. But as the weeks or months go by our motivation can start to waiver and old unhealthy habits can start to slip back into our routine. We often avoid keeping ourselves accountable when this happens, and sometimes we don't even realise our portion sizes have crept up or we're reaching for a second serving.

If you think you may have fallen into this trap, the best thing is to go back to basics and start following the program like you were when you first started. Body weight, body fat, energy metabolism, and fat oxidation are regulated by numerous hormones, peptides, neurotransmitters, and other substances in the body. Drug companies are devoting a large amount of resources to find new agents to treat obesity. Neuropeptide Y and galanin are central nervous system neurotransmitters that stimulate food intake (Bray, 1998; Leibowitz, 1995), so antagonists to these substances might be expected to reduce food intake. Beta-3 adrenergic receptor agonists reduce body fat and increase lean body mass in animals (Stock, 1996; Yen, 1995), but human analogs have not been identified that are effective and safe in humans.

To lose 5 kg in a week, you'll need to follow a strict diet and exercise regimen. Avoid foods that are high in carbohydrates, like bread, pasta, and rice. Instead, opt for lean proteins like chicken and seafood in addition to plenty of fruits and vegetables. Drink at least 64 ounces of water daily to stay hydrated and to help you feel full longer, and get minutes of a moderate activity like running or swimming every day. Many individuals and companies promote the use of dietary fiber supplements for weight loss and reductions in cardiovascular and cancer risks. Numerous studies, usually short-term and using purified or partially purified dietary fiber, have shown reductions in serum lipids, glucose, or insulin (Jenkins et al., 2000).

Long-term studies have usually not confirmed these findings (LSRO, 1987; Pasman et al., 1997b). Current recommendations suggest that instead of eating dietary fiber supplements, a diet of foods high in whole fruits and vegetables may have favorable effects on cardiovascular and cancer risk factors (Bruce et al., 2000). Although these diets are prescribed to be eaten ad libitum, total daily energy intake tends to be reduced as a result of the monotony of the food choices, other prescripts of the diet, and an increased satiety effect of protein. In addition, the restriction of CHO intake leads to the loss of glycogen and marked diuresis (Coulston and Rock, 1994; Miller and Lindeman, 1997; Pi-Sunyer, 1988).

Thus, the relatively rapid initial weight loss that occurs on these diets predominantly reflects the loss of body water rather than stored fat. This can be a significant concern for military personnel, where even mild dehydration can have detrimental effects on physical and cognitive performance. For example, small changes in hydration status can affect a military pilot's ability to sense changes in equilibrium. A significant part of weight loss and management may involve restructuring the environment that promotes overeating and underactivity. The environment includes the home, the workplace, and the community (e.g., places of worship, eating places, stores, movie theaters). Environmental factors include the availability of foods such as fruits, vegetables, nonfat dairy products, and other foods of low energy density and high nutritional value.

Busy lifestyles and hectic work schedules create eating habits that may contribute to a less than desirable eating environment, but simple changes can help to counter-act these habits. Recent studies of individuals who have achieved success at long-term weight loss may offer other insights into ways to improve behavioral treatment strategies. However, this population was self-selected so it does not represent the experience of the average person in a civilian population. Because they have achieved and maintained a significant amount of weight loss , there is reason to believe that the population enrolled in the Registry may be especially disciplined. As such, the experience of people in the Registry may provide insight into the military population, although evidence to assert this with authority is lacking. Three simple tips you should follow to lose 5 kg weight in 1 week More Proteins and fewer Carbs.

Intermittent fasting, or IF, is another effective trick that has been shown to lose body fat. Don't worry because at oneHOWTO we'll show you how to lose weight fast in an effective and healthy way so you can stop it from creeping back on. You don't need a strict diet, just make some changes in your eating habits to make your diet healthier and low in fat . In this article you will find how to lose 3kg or 7 pounds in a month and in such a simple way that you will barely notice it. No wonder, staying in shape seems like a daunting task as it is not just sacrificing on your favourite delicacies rather it calls for a holistic change, which also calls for regular workout or brisk walk. The idea of going on to a strict diet sounds like a daunting task and especially when you are looking for a quick weight loss plan.

Well, to achieve this quick weight loss target, we often spend a bomb at the gyms and fad fitness centers and what not! But what if we tell you that you can simply lose three to four kgs a week just by following this simple diet plan that too without putting in much effort. So, here's a low on the GM diet, which can effectively help in losing weight fast. A balanced diet together with regular daily exercise will enable to make lifestyle changes and attain this goal.

Examples of menus on my website will help you with meal planning. You have to watch your portion sizes and ensure you sit down and eat regular meals instead of snacking and picking. Nutrition needs vary according to individual metabolic rates and other factors such as activity levels and health status. I suggest you consult a dietitian to personalise a balanced eating pattern for your individual needs. Typically at such a consultation, the dietitian will weigh you, and ask about your medical history, eating and exercise habits, lifestyle patterns and history of weight.

They will then devise an individual eating plan and organise future consultations to track your progress and make adaptations to your present meal plan when necessary. Other eating patterns may not result in an actual calorie deficit, which is necessary for weight loss. You may find that despite sticking to a specific diet, you are not losing weight as expected. Some diets, such as intermittent fasting or keto, may claim to increase weight loss without the need to count calories.

But in reality, these diets only work because they can create a caloric deficit. If you are not in a deficit, these diets will not lead to weight loss. The combination of ephedrine and caffeine to treat obesity has been reported to produce weight losses of 15 percent or more of initial body weight (Daly et al., 1993; Toubro et al., 1993).

Both drugs are the active ingredients in a number of herbal weight-loss preparations. Weight loss is maximal at about 4 to 6 months on this combination, but body-fat levels may continue to decrease through 9 to 12 months, with increases in lean body mass (Toubro et al., 1993). This observation suggests that the combination may be a beta-3 adrenergic agonist (Liu et al., 1995; Toubro et al., 1993). Walking 1 hour each day can help you burn calories and, in turn, lose weight.

In one study, 11 moderate-weight women lost an average of 17 pounds (7.7 kg), or 10% of their initial body weight, after 6 months of brisk daily walking . I usually don't recommend calorie counting, as it can be counterproductive to maintaining a healthy, balanced approach to eating. This is one of the reasons why my online weight loss program has been specially designed so you don't have to think about calories. However, if you're not following a specific weight loss eating plan, and you need to lose the last couple of kilos then it's going to be important to locate areas of your diet where you can cut out unnecessary calories. Regular weighing and recording of daily food intake and physical activity for the first month or two of the maintenance period and during periods of increased exposure to food (e.g., during the holidays).
