Load up on these zero-calorie snacks

My e-mail inbox was full of promise when I received this article enticing me with calorie-free snacks! Are there even such things as calorie-free snacks? I mean, even chewing gum has calories. Turns out there are a few things that really are calorie-free -- namely, tea and water -- but can you really fill up on these? To a point, I suppose, but if you're having water or tea to replace a meal, you need help.

The other suggestions are not so much calorie-free as they are very low in calories and/or good for you. These items are:

• Veggies
• Berries
• Sugar-free jello (though it does contain processed chemicals)
• Egg whites
• Citrus fruits

You could eat these things to your heart's content and not see any significant weight gain, so next time you reach for that bag of chips to fill the mid-afternoon rumblings, remember these items.

What calorie-free or low-cal snacks do you enjoy?
