You may or may not know who Tom Naughton is. He is a former stand up comedian, a journalist, and more recently, a low carb blogger and the maker of the movie Fat Head. Here he gives an excellent 20 minute speech that explains why so many people never conquer their overweight in spite of diligently reducing their calorie intake, exercising and consulting the experts. Finally, disillusioned after being accused of not following their diet properly, they realize the conventional advice to cut the fat and up the grains isn't working for them. Success follows when they discover that carbohydrate restriction works for them to reduce their weight and control their blood sugars.
