I have followed Dr. Berg for several years via youtube. His videos are exceptionally well-presented, thorough, and based on repeatable science – I always check the scientific literature, which admittedly has its own fraud and corruption issues, esp, if addressing pharmaceuticals. As an aside, his personal physical appearance has changed dramatically – more youthful, reduced weight – as he has adopted many of the dietary and exercise practices he teaches. He is also willing to alter his recommendations/opinions based on new scientific discoveries. Quite frankly, he makes my “conventional western doctors” (of which I have far too many) look like ignorant, apathetic, drug puppets – which they are. I am very grateful for what I have learned from Dr. Berg and applied to my own health challenges.
