I have encountered this problem before. I used to be very fat. I have also tried some diet methods and fruit diet methods, but the effect is not great, and the rebound is very strong.
You can do some exercise properly, such as simple exercise such as air bike, hula hoop and sit-ups, and scatter the beans on the ground and pick them up.
Eat less meat in the diet and give priority to light nutrition. Pay attention to avoid eating greasy, high-sugar food or snacks. Go to bed early and get up early, and keep good sleep and living habits.
