Traci Mann, Ph.D studies diets. And what she’s conclusively found is that they don’t work.
Her findings include that dieting changes you in three ways that make it difficult to keep the weight off. These are neurological such that you become more attracted to food, hormonal so that the hormones that make you feel hungry increase while the hormones that make you feel full decrease, and biological changes that result in a slower metabolism.
Instead she urges us to focus on habits that support health while not attempting to weigh less than the lowest end of your “set point.”
Her book, Secrets From The Eating Lab – The Science of Weight Loss, the Myth of Willpower, and Why You Should Never Diet Again, goes into how to reach your leanest livable weight without relying on willpower.
