At present, there are many brands and product categories of meal replacement, including meal replacement bars (energy bars), meal replacement powder (meal replacement milkshakes), meal replacement biscuits, meal replacement porridge, etc. Among them, meal replacement milkshakes are the most popular and have the most types. Meal replacement milkshake is a way to lose weight by using the mechanism of human calorie metabolism to help control calorie intake. Meal replacement can control the calorie of a meal at about 100-300 calories, while the calorie intake of an ordinary meal is about 500- 1000 calories. Energy intake decreases and weight gain decreases. However, meal replacement cannot be used at will, and it should be configured according to the degree of obesity. A nutritious meal milkshake containing bodybuilding elements can increase lasting satiety and help control intake by adding various plant dietary fibers, high-quality protein and various trace elements needed by human body. In addition, bodybuilding elements have scientifically formulated a 35-day weight loss plan, a 6+ 1 weight loss system, and a dietitian's personalized weight loss plan. Weight managers guide and supervise weight loss one-on-one, and the road to weight loss is easy to stick to.
