I remember a time when my deskmate was an art student. She is actually quite thin, but in order to keep fit, she still insists on losing weight.
At that time, it was enough to dance mainly by dieting to lose weight. She bought cookies for meal replacement online, so she usually eats two cookies at noon. It is rare to see him eating in the canteen.
The second is to sleep more, because dancing time is longer at night, so sometimes I don't listen at all in class during the day and fall asleep at my desk. It is said that people consume less energy when sleeping, so they are hungry slowly. Presumably this is also a way to keep fit.
