What Fad Diets Actually Do to Your Body

Hoping to drop five pounds before bikini season? Want to get thin for the holidays? Sure, you can put in the time and effort it takes to eat a balanced diet, but why go the long-term healthy route when you could drop a ton of weight with a handy fad diet?! There are so many get-thin-quick schemes out there, but are any of them actually healthy?

Wondering how to lose weight fast? These diets claim to have all of the answers—as long as you’re willing to deprive yourself of almost everything delicious. There are diets that have been around forever: the infamous Master Cleanse, the grapefruit Diet, Jenny Craig, and Weight Watchers. And then there are the latest fads: the controversial gluten-free diet, the paleo craze, and everyone’s favorite: juice cleanses. Our list covers diets that are total lifestyle changes (like going vegan), and some that are only supposed to be done for 48-hours.

Of course, not all diet plans are created equal. Some of the worst diets are known to be effective, but are also potentially harmful. Some bad diets have been shown to cause fatigue, headaches, dizziness, and even more serious problems for your kidneys and heart. Sure, they get the weight off, but what's the cost of that weight loss? Bottom line, you'll want to check with your doctor before trying any of these diets. Otherwise your attempt to drop some pounds could turn in to a diet horror story.
