Dr. Ted Naiman Discusses Diet

Dr. Ted Naiman, M.D., discusses the impacts of macronutrients (protein, fat, carbohydrate) on blood sugar and insulin levels (i.e. glycemic index and load), insulin resistance vs. insulin sensitivity, naturally selected human metabolic adaptations to prehistoric diet (wild foods), our likely maladaptation (from an evolutionary perspective) to foods relatively recently introduced (on an evolutionary time scale) to the human menu, and how this all may explain why the many diseases of civilization rarely or never occurred among hunter-gatherers.

Do High Fat Diets Support High Testosterone Levels?

Does a high saturated fat diet support high testosterone compared to a low-fat diet?  
You might assume that the idea that a high saturated fat diet supports high testosterone originates with promoters of high-fat, animal-based diets, and you'd be wrong. In fact promoters of low-fat whole foods plant-based diets have embraced this idea and used it to promote abstention from saturated fats and animal products.  
Research providing evidence that reducing total and saturated fat intake reduces testosterone levels OR makes androgens less available for action is not very difficult to find, because this has been proposed by proponents of low-fat diets as a mechanism by which low-fat and plant-based diets might prevent hormone-related cancers. 
Many rank-and-file followers of low-fat whole foods plant-based diets appear unaware that leading medical advocates of such diets frankly assert that high-fat and animal-based diets support high testosterone levels in comparison to their proposed low-fat and plant-based diets.
For example, the Physician’s Committee for Responsible Medicine (PCRM), which promotes a low-fat vegan diet as a prevention for hormone-related cancers, asserts that a low-fat diet will reduce your sex hormone levels.
