why it`s risk if i reduce my weight from 56 to 47kg?

Every year Americans invest billions of dollars in weight loss diets and gimmicks, many of which yield few results. However, the lure of quick, easy weight loss is hard to resist. Despite ineffective tools, most hopeful consumers are willing to give the next weight loss fad a chance. If you're planning to start a new diet, it is important to remember the following information. Food-specific diets: Have you ever tried the cabbage diet or the fruit-only diet? These are just a couple of examples of diets that promote one "specific" food that causes weight loss. No matter how much you think you'll enjoy ice cream at every meal, inevitably you will get bored with eating the same food repeatedly. As a result, you'll eat less food than needed to maintain your weight. This type of diet will not teach you healthier eating habits or provide a balance of nutrients, and consequently is not effective for long-term weight loss. High-protein, low-carbohydrate diets: One of the most recent trends in dieting, these diets are based on the concept that carbohydrates are "bad" and that everyone has some degree of insulin resistance, resulting in poor carbohydrate metabolism. Many proponents of these diets suggest that including carbohydrates in your diet will cause weight gain. The reality, though, is that eating more calories (whether as carbohydrate, fats, or protein) than you burn will cause weight gain. High-fiber, low-calorie diets: As I've noted in many previous blog entries, fiber-rich foods play an important role in a healthy diet. They are a helpful ingredient of weight loss efforts because they provide bulk to the diet, which helps you feel fuller sooner. Be careful, though: if you plan to increase the fiber in your diet, be sure to increase your fluid intake at the same time or you may experience cramping, bloating, and constipation. High-fiber diets will help with weight loss only if you restrict calories in conjunction with addition of extra grains, fruits and vegetables. Liquid diets: Consumers face a couple of different liquid diet options. Your local grocery store and pharmacy sell over-the-counter liquid meal replacements, which can be expensive and frequently add extra calories to daily consumption if not managed carefully. On the other hand are liquid diets that require medical supervision. These diets are usually very low in calories and may result in metabolic abnormalities if dieters are not carefully monitored. Neither type of liquid diet should be used for longâ€‘term weight loss unless monitored by a health care professional. Radically changing your caloric intake in this way will not result in long-term behavior modification and healthy eating patterns. Fasting: As a way to cleanse the body or jump-start a weight-loss program, fasting has been recommended for years. However, all that fasting really does is deprive your body of nutrients and decrease your energy, leaving you feeling weak and lightheaded. If the right nutrients are not available for your cells to use as energy, your liver will convert fat stores to ketones for use as energy (ketosis). Long-term ketosis can be harmful to your health. No fad diet or gimmick will work magic for safe and effective weight loss. The following are some suggestions for ensuring a long-term healthy eating plan and getting your weight loss efforts off to an encouraging start: Eat a variety of foods. Remember, a balanced diet will ensure that you get all necessary nutrients. Get some physical activity every day. Calories in must be less than calories out to ensure successful weight loss. To keep "calories out" at a healthful level, make you get at least 30 minutes of physical activity every day. Include sources of fiber in your diet. They will add bulk and give you a feeling of fullness. Choose a diet low in fats, saturated fats, and cholesterol. You do need to consume some fat for good health. Aim for no more than 30 percent of your total calories as fat calories, of which no more than 10 percent should be saturated fat calories. Choose foods moderate in sugars. Foods that are high in simple sugars usually offer little nutritional value and will add unwanted calories. Choose foods moderate in salt and sodium. Remember that salt has been added to many foods during preparation or processing, so it's not necessary to add extra salt at the table.
