Dr Fungs approach no doubt works. Because for the most part if people try IF, they will natural consume less calories than their standard diet due to a smaller eating window. If this method works for some people, more power to them! But when a diet is treated as a “magic pill” it really gets stupid.
For every diet there is a “Dr Fung” to point out the massive benefits of their chosen path. Which diet works for the individual is completely subjective and personal. Personally Keto is just too restrictive for me, but IIFYM works great. I think people should experiment, see what works for them, what they can sustain. Let’s be honest, any of the main diets like IF, Keto, IIFYM etc are going to be better than the SAD.
