If the diet is a quick fix rather than one that promotes lasting lifestyle changes, this could pose a problem. In particular, extreme diets that promise big weight loss up front aren’t always sustainable — and you may end up overeating or even binge eating if you feel deprived. “Consider if the diet’s habits are ones you can continue throughout your lifetime, not just 21 or 30 days,” says Angie Asche, RD, a sports dietitian in Lincoln, Nebraska.
“Don't like eating meat?” says Ginger Hultin, RDN, a dietitian in private practice in Seattle and a spokesperson for the Academy of Nutrition and Dietetics. “Then don't be paleo! Travel a lot and rely on eating out? The DASH diet may end in frustration for you.” The bottom line: The diet that you choose needs to be safe and effective, while taking into account your lifestyle.
If you like the taste of apple cider vinegar, then by all means, drink up!

A few years ago, after I clocked in at 275, it was clear that my weight was a major issue, and I needed to lose some pounds. So I started counting calories and kept to 1,500-1,800 a day (usually much closer to 1,500). Though counting calories drove me to an obsessive, unhappy state a few years before, I still did it, and I was doing OK this time around. In about six weeks time, I'd lost 10 pounds.
It’s easy to see the front of a package and get lured in by misleading claims, particularly those that say they’re “free-from” something, says Taub-Dix. She points out that gluten-free foods may also be high in sugar, salt, calories, and fat and contain less fiber—and thus be weight-promoting. Reading the nutrition label will give you the real truth for what you’re buying.
