If you want to lose weight and practice more abdominal muscles, you can do sit-ups, not many at a time, separately and several times.

But to be honest, man, it's definitely impossible to reduce it to 90 kilograms. An adult of normal weight also gets 60 kilograms, which is 120 kilograms. If 20 groups come to ten groups a day, it should be 2-3 months. I have always been normal and haven't lost weight. )

However, if you feel tired, you can go hungry. The human body needs energy all the time. When you don't eat and have no energy source, you will automatically burn fat (to put it bluntly, thin people starve to death in seven days and fat people starve to death in 10 days).

If you are hungry, you can eat less high-calorie foods such as meat, cake, cream and eggs, and eat more fruits and vegetables. Even if you are not full, you can eat more fruits and vegetables. Vegetables are delicious when cooked.

If you still feel that you can't eat this bitterness, I can only say, "Dude, don't be ridiculous."
