If you don't eat, your body will consume the nutrition of your brain. The nutrition of the brain is very precious. The brain can provide nutrition for the whole body, but after you eat normally, even if you have enough nutrition, you can't provide the brain with the nutrition you need.

Often, people will become stupid, have poor reaction and thinking, and have poor memory. The probability of getting dementia in old age will be quite high!

You can't lose weight quickly, the more you bounce back. You can't always skip meals. The meat on your body is years or even decades old, and subtraction is also a gradual process. Never do this to yourself, it's a chronic suicide.

I suggest you find a fitness instructor to give you balanced and scientific guidance on your diet and exercise.

I hope my answer can save a life with rational thinking!
