How to eat less?

It is human nature to eat whatever is in front of us. We do not like to waste food, and if we are eating at someone else's home, we might think that by not finishing our food on the plate, we might be indirectly telling the host that the food was not delicious. Then the worst offenders in making people eat more are the restaurants. The serving sizes keep growing each year and are much larger than they were in the past. (Related: How to eat healthy)

So how can you lose weight?

The arithmetic is simple. Fewer calories. That can be accomplished by eating less and by burning more through exercise. While one study found that just eating fewer calories is as effective as both diet and exercise, it makes perfect sense to also exercise, since working out has other benefits too.

A new study finds that if you measure your portion size and eat in plates that don't hold a lot of food, you will consume fewer calories and lose weight.
