"low-calorie diet" 的定义和意义

What is a "low-calorie diet"?

A low-calorie diet is a dietary approach that restricts the number of calories consumed each day with the aim of promoting weight loss. This type of diet typically involves reducing calorie intake below the amount needed to maintain current body weight. The exact number of calories allowed per day varies depending on factors such as age, gender, weight, height, and activity level. Low-calorie diets often emphasize foods that are low in calories but high in nutrients, such as fruits, vegetables, lean proteins, and whole grains, while limiting or avoiding high-calorie foods like sugary snacks, fried foods, and fatty meats. While low-calorie diets can be effective for weight loss in the short term, it is important to ensure that nutritional needs are met and to adopt sustainable eating habits for long-term health and weight maintenance.
