There is no diet that will cure an overweight problem. Yes, you may initially lose weight. But I’ve heard story after story about people who have lost ten pounds on this diet and twenty pounds on another diet. But a diet will not change the problem.
Diet pills do not work for the same reason. I will repeat Diet pills do not work.
Now we are all somewhat familiar with the old standard answer of it’s simply “calories in/calories out” In other words it’s like a scale. If you add stuff on this side—you must add from the other side. Adding more stuff on the left side is like increasing your calories (eating more) When you do this you tip the scale to this side. Adding more exercise to the other side is like balancing the scale.
But humans are passive scales. We are each unique and have a metabolism. Metabolism is the rate at which your body breaks down the nutrients in food to produce energy. You are born with a certain baseline metabolism HOWEVER you can raise your metabolic rate by exercising and building lean muscles.
