This was a fascinating debate between Nina Teicholz and David L.Katz. A little spicy as Mr Katz has to put it mildly said unpleasant things towards Nina in the past. I am going to listen to again on my walk. What strikes me is that Nina produced some very good points, I just wonder if these were an answer to another question i.e. replacing "Omnivores" with LCHF, I would have thought would put her answers in her best context? I feel the question was more suited to persons advocating the "standard" west diets that mix carbs / sugars, fats and proteins in a manner many on this site disagree with. I think it too broad to place a whole foods LCHF / Keto lifestyle diet under the same umbrella as say the SAD (standard American diet) or SUK (standard UK diet). I am quite sure Nina's intention was not to answer on behalf of the status quo, as Mr Katz's responses were directed towards "standard" eaters My view is that a well formulated Vegetarian diet would have better outcomes than a standard western Omnivore diet, especially if this was the fish / egg version of the Vegetarian protocol.
