As quoted from Amazon.com:

Designed to catapult your body into a state of fat meltdown, Dr. Atkins's diet has taken America by storm. It targets insulin, the hormone that regulates blood sugar levels. 

The bodies of most overeaters are continually in a state of hyperinsulinism; their bodies are so adept at releasing insulin to help convert excess carbohydrates to fat that there's always too much of the hormone circulating through the body. 

This puts the body into a bind; it always wants to store fat. Even when people with hyperinsulinism try to lose weight--especially when they cut fat but increase carbohydrate consumption--their efforts will fail. This is why Dr. Atkins refers to insulin as "the fat-producing hormone."

Does the Atkins diet work? 

It sure does! Hundreds of thousands of people have experienced weight loss that was unattainable to them previously on the Atkins diet. As with any diet, there are always the people who had a bad experience, or who wish to bad-mouth someone else's victory.

To find out, you should really give it a shot on your own. That's the only way to know if the Atkins diet is right for you, and your needs.
