"Help me," said the desperate voice when I picked up the phone. "My blood sugar dropped and I am so tired. What can I eat?"

The caller was a co-worker who had just started a new diet. He had decided to cut out caffeine and cut back on his eating because his clothes no longer fit. But he didn't plan on being so hungry.

I suggested fruit, but he had already had three pieces of pineapple, so I sent him off to the cafeteria for a low-calorie bar to help him make it to dinner.

Like him, I used to go through a crash in the afternoon. I discovered that keeping little snacks at my desk really helps. I usually have my trusty Atkins Advantage bars, but I also keep Mrs. May's Naturals Sunflower Crunch around. They do a whole range of nuts and fruit and the products are cholesterol-free, dairy-free, GMO-free and wheat-free.

The advantage of these products is that they fill you up without sending your blood sugar sky-high and setting you up for yet another crash. There are tons of other bars out there for those that aren't low-carb, but watch the calories and sugar content. Some of them are so fattening that you might as well have had the Snickers bar you've been craving.

If you're on Weight Watchers, CounselingSeattle.com has a great list of one-point snacks ranging from cheese to cereal to soup. And WebMD.com has some great 100-calorie snacks.

So what if you just have to have a cookie? Try Kraft's 100-calorie packs.
