I am not sure why he alternates entire days of eating meat with several days of plant-based eating. I recommend eating mostly plant-based by making over all your favorite comfort foods to their healthiest plant-based forms whenever possible so you never feel deprived, and every now and then have a “cheat meal” that might be poultry-based (I regularly include fish in my diet) for something that I simply can’t translate well into a plant-based food. For example, to me there is no good vegeterian substitute for Boar’s Head Oven Roasted Turkey! But I can certainly respect his overall success.

The only point I must disagree with is keeping dairy out of your diet. Again, to each their own, but fat free or very low fat organic dairy products are important sources of calcium and protein and studies have shown they are very helpful to staying slim.
