Most rule-based diets don’t work well, because your calorie intake can go to stupid. Atkins’s notion of unlimited protein and fat doesn’t work. Most patients lose no weight after 2 months, as they are eating way too many calories. The No Flour, No Sugar Diet doesn’t work for the same reason. Patients can even get in trouble on Stillman or Dukan, because of the insane notion that you can eat as much as you want. Tthe Carbohydrate Addict’s Diet, with an hour a day where you eat whatever you want, was a weight gain program for most. If you want to lose weight, figure out a way to keep your calories under 1500 a day.
