According to the National Institute of Diabetes & Digestive & Kidney Diseases (NIDDK), diet refers to what a persons eats or drinks during the course of a day. There are many different types of diets, like the , the Paleo, Weight Watchers and many more. It is important to remember that a diet that limits portions to a very small size or that excludes certainfoods entirelyto promote weight loss may not be effective over the long term. It is much easier to maintain a diet that takes into account the foods that you like and dislike and also include combinations of foods with enough calories and nutrients for good health.
When planning your diet it is important that you consider what calorie level is appropriate for you. Is the diet that you and considering to take nutritionally balanced? Will this diet be pratical and easy to follow? Will the diet be maintainable for the rest of your life? The below information will show you what to look out for in a diet.
Low-calorie Diets. Most weight loss diets provide 1,000 to 1,500 calories per day. However, the number of calories that is right for you depends on your weight and activity level. At these calorie levels, diets are referred to as low-calorie diets. Self-help diet books and clinical and non-clinical weight loss programs often include low-calorie diet plans.
The calorie level of your diet should allow for a weight loss of no more than 1 pound per week (after the first week or two when weight loss may be more rapid because of initial water loss). If you can estimate how many calories you eat in a day, you can design a diet plan that will help you lose no more than 1 pound per week. You may need to work with a trained health professional, such as a registered dietitian. Or, you can use a standardized low-calorie diet plan with a fixed calorie level.
The selected calorie level, however, may not produce the recommended rate of weight loss, and you may need to eat more or less.
Make sure that your diet contains all the essential nutrients for good health. Using the Food Guide Pyramid and the Nutrition Facts Label that is found on most processed food products can help you choose a healthful diet. The Pyramid shows you the kinds and amounts of food that you need each day for good health. The Nutrition Facts Label will help you select foods that meet your daily nutritional needs. A healthful diet should include:
A fixed-menu diet provides a list of all the foods you will eat. The advantages of this kind of diet is that it can be easy to follow because the foods are selected for you. However the disadvanatge of this type of diet is that you get very few different food choices which may make the diet boring and hard to follow away from home.
In addition, fixed-menu diets do not teach the food selection skills necessary for keeping weight off. If you start with a fixed-menu diet, you should switch eventually to a plan that helps you learn to make meal choices on your own, such as an exchange-type diet.
An exchange-type diet is a meal plan with a set number of servings from each of several food groups. Within each group, foods are about equal in calories and can be interchanged as you wish. For example, the "starch" category could include one slice of bread or 1/2 cup of oatmeal; each is about equal in nutritional value and calories.
If your meal plan calls for two starch choices at breakfast, you could choose to eat two slices of bread, or one slice of bread and 1/2 cup of oatmeal. With the exchange-type diet plans, you have more day-to-day variety and you can easily follow the diet away from home. The most important advantage is that exchange-type diet plans teach the food selection skills you need to keep your weight off.
These diets require you to buy prepackaged meals. Such meals may help you learn appropriate portion sizes. The disadvantage to this is that they can be costly. Before beginning this type of diet, find out whether you will need to buy the meals and how much the meals cost. You should also find out whether the program will teach you how to select and prepare food, skills that are needed to sustain weight loss.
Formula diets are weight-loss plans that replace one or more meals with a liquid formula. Most formula diets are balanced diets containinga mix of protein, carbohydrate, and usually a small amount of fat.
Formula diets are usually sold as liquid or a powder to be mixed with liquid. Although formula diets are easy to use and do promote short-term weight loss, most people regain the weight as soon as they stop using the formula. In addition, formuladiets do not teach you how to make healthy food choices, a necessary skillfor keeping your weight off.
You should avoid any diet that suggests you eat a certain nutrient, food, or combination of foods to promote easy weight loss. Some of these diets may work in the short term because they are low in calories. However, they are often not well balanced and may cause nutrient deficiencies.
In addition, they do not teach eating habits that are important for long-term weight management.
Some programs or books suggest monitoring fat only, calories only, or a combination of the two, with the individual making the choice of both the type and amount of food eaten. This flexible type of approach works well for many people, and teaches them how to control what they eat. One drawback of flexible diets is that some don't consider the total diet.
For example, programs that monitor fat only often allow people to take in unlimited amounts of excess calories from sugars, and therefore don't lead to weight loss.
It is important to choose an eating plan that you can live with. The plan should also teach you how to select and prepare healthy foods, as well as howto maintain your new weight. Remember that many people tend to regain lost weight. Eating a healthful and nutritious diet to maintain your new weight, combined with regular physical activity, helps to prevent weight regain.
