I have been working out for almost 3 weeks now and i haven't seen any results yet. i feel like i've gotten bigger instead. what am i doing wrong?

Eat fewer calories: To help the tummy look flatter, one can do exercises to build very strong abdominal muscles. It will take a lot of work, and will burn off calories. One must not eat more calories than he burns off, or he cannot lose weight. Helpful weight loss foods are natural foods that take time to chew but contain few calories. Examples include carrots, celery, and iceberg lettuce (without salad dressing).
