In fact, Felicia Stoler, a registered dietitian and author of "Living Skinny in Fat Genes," warns that guzzling sports drinks may pack on the pounds.
"They're not for someone who is doing a light 15-20 minute workout or no workout at all and they really aren't any better for you than the soft drinks they're meant to replace," she says.
Not only that, studies show that sports drinks may soften tooth enamel even more than sodas, leading to cavities and tooth decay. Stoler's recommendation? Limit all sweet drinks including sports drinks and fruit juices. Stick to plain water instead.
Organic has become synonymous with healthy -- yet that's not always the case, especially when you stray from the produce section.
Take the Organic Classics line of frozen foods made by Fairfield Farm Kitchens. According to Center for Science in the Public Interest, only three of the nine entrees are low in artery-clogging saturated fat or sodium. Many non-organic choices are healthier -- and cheaper.
Slapping on organic label to junk food doesn't make it virtuous either. Sugar -- whether derived from organic cane juice, agave syrup, table sugar or high fructose corn syrup -- still delivers 16-20 calories per teaspoon and is virtually devoid of nutrition.
Eating six small meals a day is a standard aspect of many diet plans. However, some experts now say this tactic can backfire.
Jonny Bowden, author of "The 150 Healthiest Foods on Earth," believes Americans suffer from "portion distortion."
"For many, a small meal is 500 calories, so at the end of the day they've eaten over 2500 calories -- certainly not enough to lose weight and, often, enough for them to gain," he says.
Recent studies, he says, also show that some people who eat constantly will experience continuously elevated insulin levels; this may promote fat storage further exacerbating their weight issues. "They'd be better off waiting longer between meals to give their insulin production a break."
