I was 208 lbs. and was very uncomfortable so I started eating melons like cantalopes, baby seedless watermelons, honeydews and a lot of fruits I lost 20lbs in 2 and a half months. Watermellon will take away that hungry feeling and make you feel like you just ate a small dinner. and its very tasty.
Give it a shot. You can get high quality reasonably priced fruits and vegies at your local farmers market.
