There are four phases to the plan, and the first one is severely restricted in carbohydrates. The induction phase lasts two weeks, and the claim is you can lose up to 15 pounds in this time. During this time you consume no more than 20 grams of carbohydrates per day. For example, one slice of bread has 15 grams of carbohydrates, one serving of fruit has 15 grams of carbohydrates, one serving of dairy has 12 grams of carbohydrates, and one serving of vegetables can have between 5 and 15 grams of carbohydrates. It's clear that 20 grams is extremely limited, potentially unhealthy, and would be very difficult to follow for the long-term.

"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
