Diet also important: Activity is very helpful to lose weight. Exercise that makes you breath hard and sweat is great. You have to also reduce the amount of calories you eat on a regular basis. You can start by reducing your portion sizes by half. That means eat half as much food as you are used to eating. You can continue to eat as many vegetables as you want. Consistency is the key.
