I haven't tried it, but my wife has. She did a variant called the Atkins/Beach diet, but it was basically high protein and low carbs. She lost about 40 pounds the first time. The weight came back and subsequently her metabolism changed so that she did not lose weight. She's healthier now just eating smaller portions, more frequently during the day. She supposes some bodies are just designed not to lose weight. We do know larger folks that don't eat a lot that just keep the weight on. We have just retired from our days jobs recently and are finding out if a little more exercise and less job stress and more sleep with result in anything different.
