To lose weight, you have to exercise your stomach.
Doing sit-ups, dancing and doing some aerobic exercise can effectively consume energy, thus consuming fat.
As for diet, it still has a great influence. Eat seven points full. Especially for dinner, you can't eat too much, because after the afternoon, your body's digestive and absorption system is more excited and can absorb most of the nutrients, and you often seldom exercise at night, leading to overnutrition, which will lead to obesity.
In short, instead of sitting all day, you can go for a walk, jog and do some exercise.
