Before dinner, this is my experience in the gym. I usually go aerobic at about 5 pm, and eat something at 3 pm to buffer (that is, eat less and eat more) and replenish some energy. When I go to do aerobics, I basically digest, so I won't be too hungry or feel too full. You often have to wait half an hour to an hour to exercise after eating, unless you want to have a stomachache, hehe. Since you want to lose weight, don't eat after dancing. Remember to rest for half an hour before eating, otherwise it will be bad for your health. This is what the coach told me. That's how I persisted. If you are really hungry, eat some liquid food, such as porridge or milk, and remember not to eat too much. You will definitely be hungry at first, and it is easy to eat less when you are hungry. Losing weight is an ascetic, and persistence is victory. Wish you success!
