These doctors you reference have been roped in by the "Forks over Knives" crowd. I almost was, too, but towards the end of the documentary I watched, they started throwing around the word "vegan" and also were demonizing the cattle industry.

I've been doing keto for just a little over a month, along with intermittent fasting and so far, I've never felt better. The diet portion is super easy to stick to - no carbs, but plenty of fat - and it takes a while to ease into the intermittent fasting part. I can't wait to see what my blood work looks like in 6 months.
