Meal replacement food is a food used to replace dinner. Its calories are lower than normal food, but it is rich in nutrients and can provide enough satiety, so it can lose weight. The principle of meal replacement to lose weight is:
1, supplement the nutrition required for each meal.
Scientific meal replacement can provide protein, vitamins, minerals and other necessary nutrients for the whole meal. In addition, it also includes other nutrients directly involved in body fat metabolism, such as calcium and iron, which is helpful to lose weight.
2. Provide enough satiety.
For obese people, it is easy to feel hungry in the process of losing weight, which leads to a constant thirst for food, thus increasing a lot of unnecessary calorie intake. Protein, dietary fiber, carbohydrates and other nutrients in meal replacement food can provide enough satiety and avoid eating more food.
3. Reduce daily calorie intake
The principle of losing weight is that the calorie intake is less than the calorie consumption, and the effect of losing weight will be achieved if the calorie consumption is more. Meal replacement food can reduce the daily calorie intake on the premise of ensuring a balanced and sufficient nutrient intake, thus achieving the effect of losing weight.
4. Help maintain basal metabolism
Protein is one of the raw materials for human body to synthesize muscle. Insufficient intake of protein for a long time will lead to muscle loss and decreased basal metabolism, which is very important for weight loss. Meal replacement can supply the body with protein needed for each meal, maintain the body's basic metabolism, and then help accelerate the burning of fat.
5. Help reduce visceral fat
Visceral adipocytes are sensitive to insulin, so eating foods with high glycemic index can easily lead to fat accumulation; Meal replacement has the characteristics of high protein, low fat and low carbohydrate, and is a food with low glycemic index. After meals, the blood sugar rises slowly, which can avoid the sudden increase of blood sugar leading to a large amount of insulin secretion and reduce the accumulation of visceral fat.
Second, is meal replacement a diet to lose weight?
Dieting is a very common way to lose weight. The purpose of losing weight is achieved by greatly reducing calorie intake for a period of time. In layman's terms, it means "starving to death". So is meal replacement dieting a diet?
Dieting will make the intake of nutrition insufficient, leading to the lack of sufficient nutrition in the body to maintain normal metabolism; Although the calorie of scientific meal replacement is lower than that of ordinary meals, it is not lower than the basic needs of the human body, and it can ensure that the human body can fully obtain protein, vitamins, minerals, dietary fiber and other essential nutrients, so losing weight through meal replacement is not a diet.
However, it should be noted that some diet replacement foods on the market help to lose weight through the principle of dieting. This kind of meal replacement food is not recommended because of its insufficient nutrients and easy to cause weight rebound.
