If diets that promote the same approach day in and day out bore you, The 17 Day Diet may be for you.

The 17 Day Diet is actually three cycles, each lasting 17 days, plus a fourth long-term maintenance cycle. Whether you are looking to lose 10 or 100 pounds, this plan can help you lose weight quickly, avoid the dreaded plateaus, and revamp your metabolism, says author Michael Moreno, MD.

"Everyone wants fast results and the calorie confusion of this plan burns fat, achieves weight loss results, and helps dieters avoid boredom," says Moreno, a family medicine doctor at Kaiser Permanente in San Diego.

The 17 Day Diet: What It Is

Cycle 1, called "Accelerate," strips your diet down to the bare bones of approximately 1,200 calories per day. It promises weight loss of 10-15 pounds, most of which is water weight.

"This phase cleanses, hydrates, removes unhealthy carbs, improves unhealthy eating habits, and stimulates fat metabolism," Moreno says.

In cycle 2 (called "Activate,") the food plan is alternated with a slightly higher-calorie activate plan. Moreno says the zig-zag between cycles keeps the metabolism guessing, helps prevent boredom, and continues to stimulate fat burning to yield about a 5-6 pound weight loss.

Cycle 3, called "Achieve," is the stabilization period that allows healthier foods with a slower rate of weight loss of about 2-3 pounds, Moreno says.
