As you suggest, there a bundle of sites that mock Keto. However I believe the arguments need to be flipped around. Dietitians/nutritionist/doctors that still recommend the food pyramid...are recommending an obesity outcome to 40% of the people.
They can’t defend their recommendations. Instead they poop all over Keto.
Jillian Michaels is the main Keto Pooper, then you realize most of the people on her insipid show have gained all the weight back, and then some.
