If you're trying to lose weight, and are constantly hungry, you need to arm yourself with healthy, low-fat snack choices. Carrots and celery are always mentioned, and they're fine, but what if you want carbs? Choose healthy carbs such as nonfat (air-popped) popcorn with no salt. You can pop a huge bag of it, munch away along with a huge glass of water, and feel nice and full with no damage to your waistline.
A good way to lose weight is to eat out less. You never know what goes into the food you get when you eat out. They could be cooking your food with lard, for all you know. It's best to eat out less and focus on cooking for yourself.
