Three ways
First, the intake of calories remains unchanged, which increases the consumption of calories. The advantages are: eating and drinking have a good quality of life; The disadvantage is that only the energy consumption of teenagers increases with age, while that of adults is basically stable. In this case, the only way to increase consumption is to increase exercise, which contradicts your requirement of not exercising. Moreover, because people's living standards are very high now, it is easy to consume 10,000 calories, while most of the exercises needed to consume 10,000 calories are difficult to do. Moreover, if you consume a lot of calories, even if you exercise all day, it is difficult to exceed the amount of exercise, which is why some people exercise a lot and are still fat.
The second way is to consume the same amount of calories and reduce the intake. The advantages are: no need to increase the amount of exercise, high success rate; The disadvantage is that there are certain taboos in eating, which has a certain impact on the quality of life of eating goods to a certain extent. We know that the space of the stomach is relatively certain. In order to reduce calorie intake when we are "full", we have to eat more low-density calorie foods. What is low-density food? For example, cucumbers, three cucumbers are basically full, and its calories are far lower than that of an egg. Then, mastering the density and calories of different foods, skillfully matching them under the premise of ensuring that the body must be nutritious and healthy, and cooking your favorite foods reasonably is the premise and key to success. This is also the key point of this weight loss method.
The third method is the synthesis of the first two. Advantages: the fastest reduction; Disadvantages: it is difficult to implement and conflicts with the theme of no movement.
