Diet (from the Greek diaita - lifestyle, diet), a specially designed diet in terms of quantity, chemical composition, physical properties, culinary processing and intervals in food intake.
The diet of a healthy person, corresponding to the profession, gender, age, etc. (rational diet), is the subject of study of food hygiene. The development and recommendation of diets for the patient is engaged in dietetics - the science of medical nutrition. When prescribing diets, one proceeds from functional, pathomorphological, metabolic, enzyme and other disorders in the human body.
A correctly selected diet provides the most favorable background for the use of various therapeutic agents, enhances the effect of these agents or has a therapeutic effect. The preventive value of the diet is that it delays the transition of acute diseases to chronic ones.
Don't eat after six in the evening. One of the most common myths. In fact, what matters is not how much you eat, but how much you eat and how active you are. If you ate at eight and went to bed at 12, then there is nothing to worry about. Especially if your dinner was light.
The more difficult the diet is to maintain, the more effective it is. The effectiveness of any diet is determined by the ability of more people to use it and the achievement of better results for weight loss or better health.
There is a medicine that can lead to weight loss without dieting and torment. There are no medications that can lead to weight loss if a person does not follow a diet. Indeed, weight gain is based on a completely normal process - the accumulation of fat by adipose tissue. And the body does it at every opportunity. Accordingly, there is not and cannot be a remedy for physiological processes. All weight loss drugs either enhance the effectiveness of the diet or improve its tolerance.
The less we sleep, the more actively we lose weight. It looks quite logical. Indeed, in a dream, our metabolism slows down and less energy is spent. So if you sleep less, fat will disappear faster. Quite the opposite is true. Scientists believe that proper sleep is an essential part of a weight loss program. During sleep, the level of a hormone that signals hunger to the brain decreases. The researchers concluded that sleeping an hour less than normal can lead to hormonal imbalances.
Excess weight from eating a lot. This is not entirely true. As a rule, excess weight, obesity, cellulite are the consequences of an improper lifestyle or the onset of a disease.
If parents are obese, then overweight in their children is almost inevitable. Indeed, such children tend to be overweight. But if they eat right, do not abuse fats, they will remain slim for a long time. Conversely, if there are a lot of fatty and high-calorie foods in the daily menu, then weight gain is inevitable. Even in the absence of a tendency to be overweight.
Limiting the amount of food leads to weight loss. The opinion is wrong. It is normal to eat three meals a day at regular intervals. Skipping one meal will result in the next one being plentiful. And since the body is not able to burn the increased amount of calories, it "stores" them in the form of fat. Experiments on rodents showed that the same amount of food served daily in three meals did not affect the change in weight, while fed only in one meal led to a sharp increase in weight. If we are forced to refuse any meal, it is worth evenly distributing the calorie content to the remaining ones, as well as drinking more drinks.
Losing weight is incompatible with eating your fill. This is not true. The main thing is the correct selection of the diet, good tolerance to the diet, its physiology and harmlessness. The ideal menu keeps the person feeling comfortable throughout the entire period of weight loss. And only in this case, weight loss will be successful, and the result will be lasting.
They don't get fat from fruits. All fruits contain sugar, while some (grapes, bananas, and dried fruits) contain more sugar than others. While on a diet, we must, however, consume a certain amount of fresh fruit due to the content of vitamins, mineral salts and fiber in them. Choose less sweet ones whenever possible, such as watermelons, grapefruits, peaches, strawberries and raspberries. It should also be remembered that an apple eaten between meals effectively "tricks" our hunger.
Juice should not be drunk during diets. Here you need to clarify what is considered juice. Store juice or juice drinks contain sugar and concentrated substances. If you cannot do without juice, try to drink freshly squeezed juices, they are much healthier. Better yet, replace them with the fruit itself. After all, they contain fiber, this will improve the functioning of the digestive tract and relieve the incoming feeling of hunger.
A salt-free diet will help get rid of swelling and other skin problems. Avoiding salt entirely can be detrimental to your health. With a lack of salt in the body, the internal balance is disturbed and the body begins to protest. If, in the fight against toxins that prevent you from looking good, you use about 5 liters of water, you will face bad consequences, namely the occurrence of seizures, weakness in the body, and even a heart attack is possible.
Drinking plenty of water will help you lose weight. Drinking plenty of water will not lead to weight loss. It is good for health, but there is no information that people have lost weight from water. They were probably just replacing high-calorie juices or soda with regular drinking water. Our body needs from one and a half to two liters of water every day, it is worth remembering that a glass of water, drunk twenty minutes before a meal, reduces the feeling of hunger.
Diuretics and laxatives speed up the weight loss process. These funds only stimulate the excretion of water and in no way contribute to a more intensive expenditure of fat. Their use when overweight is pointless. And it is also harmful to the body.
Exercise definitely contributes to weight loss. There is serious scientific research showing that intense exercise leads to weight gain rather than weight loss. Exercise is undoubtedly necessary, but the intensity of the load must be selected individually.
Exercising on an empty stomach will help you burn more fat. When you exercise, your body burns fat as well as the carbohydrate stores from the food you eat. If you're not eating or snacking lightly, you have no carbs to burn. But this does not mean that you will burn all the fat (physical characteristics). In addition, nutrients necessary for muscle function are burned. Deteriorating metabolism is not the goal of a diet. Exercising on an empty stomach will burn a few more calories than if you had eaten. But it won't do you any good, because you will get tired faster. Ideal if you eat 3-4 hours before training, or have a light snack 1-2 hours in advance.
Wearing warm clothing during strenuous physical activity promotes weight loss. In fact, heat can reduce the risk of tearing ligaments and muscles during strenuous exercise. But if you put on an excessive amount of clothing, this can lead to rapid respiratory and cardiovascular fatigue. And, of course, this will not in any way affect the change in the contours of the figure.
Eating in moderation is a sufficient measure for weight control. Weight gain can also be observed with a moderate diet, if the proportion of fat exceeds 50%, or when leading an unhealthy lifestyle.
It takes a lot of willpower to lose weight. Yes, willpower plays a role. But much more your weight depends on your genetic predisposition, on your health, your environment, your level of activity.
Dramatic weight loss is not safe. The opinion is fair. Losing too much weight can, by and large, have a detrimental effect on the body. Rational weight loss should be planned for several months, because the weekly weight loss should not exceed one kilogram.
