We'll start with low-carb diets; they have an effect that is very difficult on the body. They cause your body to lose due to ketosis. They cause you to lose lean muscle tissue and lean muscle is your metabolism, your resting metabolism. So the key on a low-carb diet, obviously, is to drop a lot of weight quickly and you do. If anyone asked me if you can lose weight quickly on a low-carb diet, I would absolutely say yes -- you can lose it fast .
My plan was compared to the Atkins plan on Dateline NBC about two years ago. The person on Atkins lost the weight faster but at the end of the results the person who had been on Atkins had regained the fastest. The gal that I helped kept it off and lost 20 more pounds. It was interesting to see that on television. That is the number one reason; low-carb diets cause your body to go into ketosis which causes the body to lose approximately 25% of the weight loss from muscle. So if you lose four pounds of weight on a low-carb diet one of those pounds is muscle. And if you lose one pound of muscle, you, decelerate your metabolism by 50 calories a day, meaning that you burn 50 calories less a day. Most people lost five, six, 10 pounds of muscle from dieting back and forth and that's very dangerous.
That is really the core message that catches a lot of people's eye with the 3-Hour Diet? because a lot of times there aren't too many books that will tell you the truth or give you the research. Does it work, yes, but at what expense? That's the challenge with low-carb diets.
What's interesting with my clients is that a lot of them are on a low-carb diet originally before they work with me. They only may eat usually one meal a day -- dinner. Dinner is usually high protein, low-carb. They will skip breakfast, they skip snacks and they skip lunch. If they skip those meals, unfortunately the body goes into a starvation mode. That is the second most popular diet plan for a lot of people who are overweight -- starving, just not eating. They think they are fat and they don't want to eat. They think they can tough it out in the morning and they stop eating. When you stop eating for more than three hours and 15 to 20 minutes, from what the science shows, the body literally flips a switch on.
