The Controversies

  1. Consumption of carbohydrates in moderate amounts can be good.
  2. High-protein diets can actually lead to weight gain.
  3. Slow fat loss can hamper the hormone levels.
  4. Small deficits of calorie intake can slow down the metabolism rate.
  5. Salicylate in Aspirin can regulate metabolism.  
  6. Only rigorous gymming cannot be beneficial.
  7. Alcohol can be used to accelerate fat-burning.

The controversies around the book’s extreme measures and the prohibition on it can be assumed to be the conspiracy of corporate companies that make money by selling diet pills, detox guides, gym memberships, and medicines at exorbitant prices. This book, after all, shows ways that only require clean eating and moderate workouts.
