Hello, the average adult's daily basal metabolism is about 1200- 1400kcal. Reasonable diet will control the daily intake of calories at about 1400 calories, so that the body can provide calories by burning metabolic fat. So is it okay to drink only milkshakes during weight loss? Of course not. Generally speaking, milkshakes have about the same calories as apples. Simply drinking milkshake can't satisfy the daily calorie intake of human body. If long-term low calorie intake (below 1200 calories) belongs to dieting behavior, it is easy to rebound. How to use milkshake correctly? Milkshake is specially developed for sub-healthy obese people, and the whole process is guided by professional weight management personnel. Eating milkshake only needs to replace breakfast or dinner, and the rest of the dinner is eaten normally, which not only meets the daily intake demand, maintains the nutritional balance, but also helps to control calories and make you lose weight easily and healthily.
