Diet book part 1 I've started reading a book about dieting and why everyone fails, from time to time I'll be posting some of the "reasons" that diets fail on here among other gems. Today I've read set point, genetics, starvation mode, and will power are all reasons why people can't lose weight.   Set point = vague description about your body wanting to stay in a certain range and fighting your gain/loss otherwise.   Genetics = twins separated at birth weight depend more on the birth parents and not the adoptive parents.  Starvation mode = your body converts more energy to fat because it thinks you're starving.  Willpower = the next chapter is titled "the myth of willpower" and is sure to be entertaining.  "Lack of willpower is not why people can't lose weight or maintain weight loss on a diet, and strong willpower is not why thin people stay thin. Obviously, the proof above is all utter nonsense.  But, here's your chance to list the reasons why all of them are no more than excuses.  And, begin!
