A comparison of Zone, Atkins, and other diets

Gary Taubes is citing in his book a fascinating study that compares the impact of the Atkins, Zone and other diets. The diets compared are the following

  • Atkins: 20g of carbs / day for 2-3months, then 50g; unlimited fat & protein (at this level of carbs this diet is arguably almost Paleo as well)
  • Traditional: calorie restriction, carbs 55-60% of cals, fat < 30%, saturated < 10%
  • Ornish: fat <10%; meditation & exercise
  • Zone: 30/40/30% of cals from protein / carbs / fat

Nutrition and Metabolism
