Summer is just around the corner, and that means beaches, bikinis, and (almost) bare bodies. If the thought of being seen in a bathing suit seems as frightening as a scene from Jaws, you might be tempted by diets that promise quick and easy weight loss. But will they really work? Here's a look at seven diets that don't live up to their promises

These weight-loss plans promise that you’ll shed pounds by flushing out your system, preventing your body from absorbing fat, or tricking your metabolism. Can you believe their claims?

Detox Diet. A detox diet (also known as the lemonade diet, master cleanser, or maple syrup diet) promises to cleanse your body of toxins and flush out fat. Experts say the diet may cause you to lose weight because of the severe calorie restrictions, but you’re likely to regain it very quickly. It can also cause serious side effects, such as irritability, fatigue, and digestive problems.
Diet Pills. Most diet pills promise extreme weight loss, either by suppressing your appetite or preventing the absorption of fat. Despite the dramatic claims, diet pills are generally ineffective and can have dangerous side effects, most commonly causing digestive problems.
Calorie Shifting. This plan claims that if you restrict calories on some days and eat more on other days, you’ll “trick” your metabolism, losing weight without worries of regaining it later. Calorie shifting may require dieters to eat a dangerously low amount of calories, leading to dizziness and lightheadedness.
