Things You'll Need
Eliminate all white flour products from your diet and eat vegetables instead (preferably green leafy vegetables). Broccoli has protein and many health benefits so you can start with that, but don't forget the hundreds of other green leafy vegetables that are out on the market as well. Doing just the one step will help you lose stomach weight fast.
Eliminate sugar from your eating plan. Chocolate, candies, cookies, etc are super fun while you're eating them, but they completely sabotage any healthy diet and make your stomach fat. Sugar also makes you tired. If you eliminate all simple sugars from your diet, you'll soon be amazed at how much stomach weight you'll lose.
Be sure to eat five small meals a day. This takes some getting used to, but trust me, when you replace white flour products with vegetables and stop eating simple sugars, you will want that small healthy meal every 3-4 hours. Be sure to eat a source of protein at EVERY meal (eggs, meats, nuts, etc) since protein is the one thing that will keep you full until the next meal. If you think of your plate in thirds, one third will be protein, one third vegetables and one third complex carbohydrates
(sweet potato, whole grain wild rice, etc). Eat things that look like they just came from the farm or field - the more natural it is, the healthier it is for you and the faster you will lose the stomach weight fast.
Drink a lot of water to help increase your stomach fat weight loss. You should drink at least 3 tall glasses of water a day. Those sugar drinks, coffees and sodas are going to get you NOWHERE - you will not lose weight fast while consuming those products. They sabotage your healthy diet just like cookies, cakes and candies. Eliminate the sugar drinks and drink water, milk and not from concentrate orange juice instead. V8's are great too if you can stand the salt.
Start exercising if you haven't already. Do cardio 4-5 times a week for 30-60 minute intervals. Do abdominal exercises too, but you need to realize that losing stomach weight fast has more to do with your diet than doing hundreds of crunches in the gym (and if you're doing hundreds of crunches, you're doing them wrong! - you should be exhausted at 12 reps per set). Weight training will help you burn fat fast too, so don't be afraid to pick up the weights.
