The weight loss effect of coffee has nothing to do with exercise, but only with the fat and calories consumed. Don't break down some fat while eating more fat and calories.
Drink coffee to lose weight, exercise to lose weight, and lose weight together will be more obvious.
If you are a college student, and coffee has many benefits, be careful not to drink on an empty stomach, not to overdo it, and not to affect your rest. Primary and middle school students should try to drink less caffeinated drinks.
