With the improvement of living standards and the convenience of transportation, some people are getting fatter and fatter. In fact, the root cause of obesity has a lot to do with our life and diet. Because body shape and weight affect life and health, more and more people want to change their body shape and weight. Therefore, in recent years, various meal replacement products have entered our sight, and various weight loss products have emerged one after another. As the saying goes, if meal replacement products are completely used instead of meals, you will only get the result that runs counter to the original intention of losing weight. ?

Diet instead of losing weight is actually changing dinner into some kind of food. Common meal replacement weight loss products on the market include meal replacement biscuits, meal replacement juice, meal replacement milkshake, and porridge with three meals.

What is the theoretical basis for weight loss of meal replacement products? It is nothing more than these three, as follows: first, provide a sense of fullness, so that you will not feel hungry.

Overeating is the main factor leading to obesity. Meal replacement products limit appetite by providing satiety, so as to shut up, thus achieving the purpose of losing weight. The satiety provided by meal replacement products can never be compared with normal food, nor can it meet our needs for food selection, fragrance and shape.

And long-term consumption of meal replacement products will lead to gastrointestinal discomfort, which is difficult to adhere to.

For example, a friend of mine, Ms. Zhang, recently started eating meal replacement products 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 taking it.

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. Insufficient calorie intake for a long time, especially when the human body lacks enough carbohydrates, can easily lead to adverse consequences such as low basal metabolism, unstable blood sugar and slow response.

Third, advocate balanced nutrition and single actual nutrition.

Does the human body need 7 kinds of nutrients every day? Protein, fat, carbohydrates, vitamins, dietary fiber, minerals and water. Lack of any nutrient in the body will lead to unbalanced nutrition and sub-health.

Meal replacement products claim to contain all kinds of nutrients needed by human body, which can meet the nutritional needs of human body after accurate measurement and proportion.

The theory and propaganda are perfect. In fact, the quality of meal replacement products is often uneven, and most of them are only from protein, with fat and carbohydrates, and the nutrition is relatively simple. Eating these meal replacement products for a long time can easily lead to malnutrition and other phenomena. Once a friend substituted meals and got hypokalemia as a result.

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 even more serious anorexia nervosa.

So meal replacement can't 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 keep a good attitude, so as to achieve the effect of healthy weight loss without rebounding.
