Just wondering if anyone knows what are the best foods to eat so as to keep a flat stomach

I heard it said... Remove the whites from your diet.

Some good suggestion here. I have tried a number of these. Seems like my biggest issue is pushing away from the table sooner   

Smaller portions can make a big difference. Although its easier said than done.

Definitely cut out the saturated fats and do regular exercise, even if its just a brisk walk. The very best thing to do is to take a 15 min walk immediately after your meal. This way your body takes the fat from the food you've just eaten rather than storing it for later.

Best advice would be to eat fresh organic food, maintain an element of portion and calorie control. Exercise at least 3 times a week. Flat stomach = some work.

Losing weight is all about math.

Put less in then you put out and you will lose weigh - simple as that.

Stick to the foods of the earth: vegetables, fruits, etc 

Good luck!

I'm on my post xmas diet and this thread is making me hungry.

I find that proteins in general are good. I find that not drinking liquids 30 minutes before or after a meal allows the body to naturally digest your foods too.

The person who said the carrots and cookies analogy has a point, but so does the previous poster.

I am a trainer. 100 percent of the time, when people properly count calorie intake, even with 15 minutes more a day of exercise only, they lose weight.

Now, if you had 250 calories of carrots (properly an entire small bag) or 250 calories of cookie (probably only 2 medium cookies), you would lose weight. It has nothing to do with weight in this case, but everything to do with caloric intake.

It's a balance. If you eat only fruit, you feel sick. Only protein, you feel sick. Count your calories.
