Remember to exercise before meals. Muscle work after meals. .
Suppose you are MM, 18 to 26 years old, tall 165 and weigh 70KG. The daily calorie intake is less than 1500 calories. Then work out for 3 hours.
Then you can lose 50KG a month. This is theoretical.
But what I said is hard to do. This is the devil's diet in hell. . It will do great harm to the body.
Excessive exercise can also do harm to the body.
