Do "cold turkey" programs work for some people? Absolutely, because some people learn best and work best that way - with rigidity, structure, and black and white rules.
But for some of us, these programs backfire. When you tell us not to have something, it becomes all we want. When our diets get too strict, our bodies feel the stress of dieting and start holding on to excess weight harder. Our appetite increases, our cravings get more intense, and our motivation to train and eat well goes out the window, too.
So if that's you, if sugar detox programs do not work for you no matter how many times you try them, why do you keep signing up for them?
