I am looking at signing up to the online programme and starting on the Fast 800 for 12 weeks.
Two years ago I followed The Blood Sugar Diet and had successful results but, not being (pre-)diabetic, I did not follow a strict 800 calorie day and mostly focused on reducing my carbs and the change in eating habits.
I am a solid, 6 foot, 165kg, male and everyone I speak to feels that 800 calories is insufficient given my size. The most common reaction is “How does this magic number of 800 work – isn’t everybody different?”
Is 800 sufficient regardless of current body mass?
Is there supporting evidence I can point the naysayers to?
