Full disclosure: I have experimented with most (though not all) of these popular weight-loss methods: from an all tuna plan in 7th (!) grade to the college era diet that allowed me to consume as many Snackwell cookies and Heinekens as my heart desired. Then there was the “caveman” diet I tried with my husband, a fan of the workout that espouses it. This left me craving white carbs so desperately I was ready to stuff a bagel into a baguette and call it a bagel/baguette sandwich. And eat it.
And yes, many of these diets worked (not counting the beer and cookies)… at first. The reason, say experts, is that any time you drastically change your eating habits—in any way—you're going to see results on the scale. The problem is sustainability. “If you can't envision sticking with a diet for the rest of your life, then it's not a good eating plan,” says Janet Brill, R.D., Ph.D., a consultant in private practice and author of Cholesterol Down. We asked Brill and Nicolette Pace, R.D., CDE, about nine of the most popular dieting myths of the last 30 years—and why they're more hype than help.
