Rational use of nutritious meal substitutes is helpful to lose weight. In the high-protein diet to lose weight, the total energy per day is 1200 calories, and carbohydrates are also food, accounting for 40% of the energy supply. In addition, there is 30% fat and protein. By increasing the energy supply ratio in protein, we can reduce our hunger, increase our satiety and help us lose weight. At the same time, protein's high energy supply ratio can bring energy consumption and maintain muscle content. The content and composition of whey protein powder used in this scheme are relatively simple, and the quality of protein provided is also sufficient. If protein is increased through diet, it may lead to the increase of fat or carbohydrate, which is not conducive to achieving a high-protein diet. In addition, using the so-called soluble dietary fiber as a substitute for nutritious meals can increase satiety and reduce hunger, and at the same time, the energy content and sugar content are less, which has relatively little influence on the total calories of the body and increases satiety.

Nutritional meal replacement should also be combined with other nutritional elements, including carbohydrates, grains and fresh vegetables, fruits, meat, eggs, milk and so on. Nutritional meal replacement only plays an auxiliary role in breakfast, lunch, dinner or extra meals, which helps to adhere to the high-protein nutritional weight loss plan. The second stage is often a light diet plan to prevent rebound, or return to the essence of life, limit energy and balance nutrition. This kind of diet plan often does not need the help of nutritious meal substitution. Therefore, nutritional meal replacement is only used during weight loss, and it is an auxiliary component in the selected weight loss program. At the same time, remember that besides diet, scientific exercise must be helpful. Only diet and exercise, at the same time, pay attention to alcohol and tobacco restrictions and psychological balance, that is, the most important thing is a scientific lifestyle, which is the basis of weight loss.
