Westman is the OG ketogenic researcher. He has been supervising ketogenic diets in clinical trials and in obesity clinics for longer than almost any living person with the exception of
Not surprisingly they were coauthors with on the old new Atkins book. They aren’t all on the exact same page with each other or with Dr Atkins. Dr Atkins has his 4 phases only the first of which is ketogenic, his target audience is the everyman. Eric Westman has his “page 4” list of foods to eat to keep it simple - his target audience is the obese. Stephen Phinney have carbs at 20% of energy, protein 1-2 g/kg lean mass, and let satiety modulate fat intake. Jeff Volek appears to be slightly more nuanced with a modest caloric limits on fats. Virta (ie: Stephen and Jeff) has a target of getting all type 2 diabetics off drugs and on their app.
Carl and I were a little lower (1-1.5g/kg) on protein because our target is to help brittle type 2 diabetics reverse their disease so they live longer, and fat to satiety so that extra life is not a miserable one.
But all of the above are just nuanced versions of the same diet.
The WHK diet which I reviewed before I invited her here is a further nuance taking Eric’s idea of a simple food list, adding portion control (eg: a minimum of 2 palm sized portions of meat per meal), and cycling between a higher calorie day and a lower calorie day so the body doesn’t see down days as deprivation that require a reduction in caloric expenditure. Her target is people who just need something simple. But also helping experienced ketoers (incl. some who run large keto groups on FB) to break through plateaus.
She runs a free 100 day group program, and is supported by patreon donations for those who want one-on-one coaching.
NB: I should really make a Westman emoji.
