100 Calorie Packs: Dieter's Dream Or Nightmare?

If your resolution was to lose weight and eat healthier this year, we hope you're still sticking with it.

One way to cut back is to munch on those new individual 100 calorie packs. Is it a good way?

"I think so because we have lost size of portions in this country, they have grown and grown and we do not know what a serving size is anymore," said Debra Krummel with the University of Cincinnati.

Forty to 60 percent of the American population is obese and that often carries over to their children. The packs are a positive step to help control our consumption of non-nutritious snacks.

"It could prevent overeating if your not buying a large bag because people have a tendency of eating the whole bag and not just ten chips," said Krummel.

In addition to watching calories, regular exercise remains key and the pros stress the 100 calorie packs should not be used as a replacement for healthier options.

"Snacking should be whole foods not anything like that, you should be eating lean, 80 percent of your physic comes from your diet, not exercising and 10 percent comes from exercising and 10 percent from genetics," said Tessa Dillon, a personal trainer.

One major drawback -- every time you reach for your tasty bag of a hundred calories, you're going to pay more at the register for the convenience. One six-pack box costs around $3.

As diet experts have told us, another key is substituting protein and other healthy food for starches, no matter how small the portions.
