Here are some tips that I hope you find helpful.
1.Eat in moderation...DO NOT clean your plate, leave some food on your plate instead of eating everything.
2. A friend of mine lost 20lbs in 3 weeks on a rice diet. She would fix butter rice, roast beef with rice, eggs and rice, vegs and rice. They were all one pan meals.
3. Don't try to loose too much too fast...you want your skin to shrink with you as the weight comes off.
4. Get an exercise video that concentrates toning the stomach area.
Hope you can get something from this
