I have not been to his clinic but as a woman in her mid forties unable to lose weight and now diagnosed with type 2 diabetes I am gain SO much knowledge from Dr. Berg’s videos. They make sense and I feel healthier. I’m only on day 20 of IF and so far I love it. I feel less hungry, losing some weight and overall eating healthier trying to do Keri as a vegetarian. Thank you, Dr. Berg!
