That’s in part because when you restrict calories, you restrict nutrients. As a result, you lose weight on a crash diet, but much of it is lean, healthy muscle tissue. With less muscle, your body’s metabolism is set at a lower point. So when you go off the diet, even if you eat the exact same number of daily calories as you ate before, you’ll actually gain more fat than you originally carried.
A systematic review of 40 studies found that intermittent fasting was effective for weight loss, with a typical loss of 7-11 pounds over 10 weeks. [2] There was much variability in the studies, ranging in size from 4 to 334 subjects, and followed from 2 to 104 weeks. It is important to note that different study designs and methods of intermittent fasting were used, and participant characteristics differed (lean vs. obese).  Half of the studies were controlled trials comparing the fasting group to a comparison group and/or a control group (either continuous calorie restriction or usual lifestyle), with the other half examining an intermittent fasting group alone. A brief summary of their findings:
Jeni S., a 31-year-old mom of two and group fitness instructor, first discovered cleanse diets after talking with a fellow fitness instructors. "I was complaining to her about my post-holiday bloat and she recommended I try a cleanse to 'flush' it all out and sort of reset everything." On her friend's recommendation, Jeni started with the Shakeology Jumpstart Cleanse—"a nutrient rich, calorie restrictive cleanse designed to help rid your body of undigested food and other toxins." She adds, "The goal is to get as many nutrients with as few calories as possible."
