How to lose weight in a certain area, for example, the waist / face / legs?

It's not possible to burn fat on just one area of your body, but lowering your overall body fat levels will slim down your stomach, waist, legs and thighs — in addition to your back, arms and face. To get the slim, toned appearance you seek, you'll need to pair a balanced diet with a workout program that promotes muscle growth. You shouldn't expect a major change in your physique overnight, but stick to your diet program for gradual weight loss that delivers long-lasting results.
