As the saying goes, practice three points and eat seven points. In fact, I personally even think that the effect of diet control is better, faster and more direct than fitness. Of course, the premise is to control the diet and adjust the diet structure, rather than dieting, which is very healthy and moderate, which will hurt the body more. Because people eat and eat their own meat, so how to eat fat should be how to control their mouth and how to lose weight.
All these are about the necessity of diet control if you exercise to lose fat. Of course, if you are in good shape and don't have a particularly strong desire for goals, diet control is actually dispensable, and it doesn't matter if you don't control your diet and exercise according to your own habits.
Nothing is absolute. So what kind of lovely people need diet control and management very much during fitness? Friends who lose weight first, then gain muscle. These two categories, especially those with clear goals, may really need to control their diet and quit many things.
For example, to reduce fat, it is necessary to reduce the intake of high-fat things and eat more low-calorie and high-nutrient things. Then people who gain muscle need to eat more things with high protein content, which is beneficial to muscle growth, and at the same time, they need to eat enough things that their body basically consumes to maintain muscle.
Everyone should know that people with high muscle content will lose their muscles if they don't eat properly, which can be said to be very painful, especially for some boys who have high requirements for muscles.
So it's up to you whether you need control or not. Happiness is the most important.
