Diet replacement to lose weight actually means replacing dinner with a certain food. Common meal replacement weight loss products in the market include meal replacement biscuits, meal replacement juice, meal replacement milkshake, and so-and-so porridge with three meals.
What are the theoretical bases for weight loss of meal replacement products? They are nothing more than these three, as follows: First, provide satiety and make you feel that you won't go hungry.
Excessive diet is a major factor leading to obesity. Meal replacement products limit appetite and keep your mouth shut by providing satiety, so as to achieve the purpose of losing weight. However, the satiety provided by meal replacement products can never be compared with normal food, nor can it meet our needs for food color, flavor and shape.
Moreover, long-term consumption of meal replacement products will lead to gastrointestinal discomfort, so it is difficult to adhere to it.
For example, a friend of mine, Ms. Zhang, recently started to eat a meal replacement product to lose weight. She only eats lunch normally every day, and breakfast and dinner are replaced by meal replacement products. After taking it for a period of time, Ms. Zhang lost 6~7 pounds, but her stomach was always uncomfortable and she had to stop.
Second, the low calorie intake of meal replacement products is lower than the minimum calorie standard of human body.
The principle of meal replacement to lose weight is that the calorie intake is less than the calorie consumed by the human body, so as to achieve the purpose of losing weight. The calories provided by meal replacement are usually lower than those consumed by dinner, so you can lose weight.
The calorie content of meal replacement products on the market is often lower than the minimum calorie standard recommended for weight loss. Long-term insufficient calorie intake, especially when the human body lacks sufficient carbohydrates, is likely to cause adverse consequences such as low basal metabolism, unstable blood sugar and slow response.
Third, advocating balanced nutrition, the actual nutrition is single.
Does the human body need 7 nutrients every day? Protein, fat, carbohydrates, vitamins, dietary fiber, minerals and water, and the lack of any kind of nutrients in the body will lead to unbalanced nutrition and sub-health.
The meal replacement products claim to contain all kinds of nutrients needed by the human body, which are accurately measured and matched, so they can meet the nutritional needs of the human body.
The theory and propaganda are perfect. In fact, meal replacement products are often of different quality, and most of them are only from protein, with fat and carbohydrates, and the nutrition is relatively simple. Long-term consumption of these meal replacement products can easily lead to malnutrition and other phenomena. Once a friend had a meal replacement, and as a result, he suffered from hypokalemia.
Moreover, even if meal replacement products are really nutritious, they cannot completely replace meals, nor can they replace meals for a long time. This is definitely unhealthy, which will lead to malnutrition, endocrine disorders and other problems, and even more serious anorexia nervosa.
Therefore, meal replacement can not really play a role in losing weight. The way to lose weight healthily is to develop good living habits and eating habits, keep enough sleep, exercise moderately every day, and maintain a good attitude, so as to achieve the effect of healthy weight loss without rebounding.
