Beef stimulates as much insulin release as brown rice: http://www.ajcn.org/content/66/5/1264.abstract ( http://www.ncbi.nlm.nih.gov/pubmed/9356547 ) - The acute effects of four protein meals on insulin, glucose, appetite and energy intake in lean men: http://www.ncbi.nlm.nih.gov/pubmed/20456814 - James Krieger did a write-up of this and a few other studies that excerpted the relevant graphs for anyone who doesn't have full-text access to clinical journals at http://weightology.net/weightologyweekly/?page_id=319
His claim has always been that calories in/out doesn't matter, that you can consume 2500kcal of mixed carbs/protein/fat and grow obese or consume 3000kcal of protein/fat with 0 carbs and grow lean which is a violation of thermodynamics and completely off-base to how human metabolism actually works.
The difference? Diet. Entirely diet - I increased exercise and it didn't do jack, I started counting calories and the pounds just melted off; and I didn't have to turn into a carb-phobe, a lipid-phobe or cut out any macronutrient to do it, I just had to learn what actual food was and what a portion really looked like.
Taubes was of course taken by complete surprise by the existence of Acylation Stimulating Protein http://www.ncbi.nlm.nih.gov/pubmed/10355026 [nih.gov] which is about two-three orders of magnitude more potent driver of fat storage than insulin is and stores fat in the complete absence of insulin in your system, and he also failed to take into account that protein stimulates more insulin release than carbs do, which leaves both parts of his hypothesis falsified.
He's also claiming that obese individuals will add body mass in absence of excess calories based on self-reporting of calorie intake. Which would leave you with mass appearing from nothing, or you'd go with the alternate explanation which is that people will under-estimate and under-report their intake in proportion to their level of obesity:http://www.ncbi.nlm.nih.gov/pubmed/9312790
