Well SupportedDecreasing monounsaturated and saturated fat while increasing polyunsaturated fat intake, keeping total fat stable, decreased total testosterone by 15% in one study.Well SupportedOrgan meats like liver, heart, spleen, kidney, and pancreas were considered part of 'meat' by ancestors and should be included in the diet for improved quality of life.Well SupportedDietary fat intake is necessary as a substrate for producing cholesterol-derived steroids, including hormones like testosterone and estradiol.Well SupportedHigher dietary fiber intake in low-fat diets may increase testosterone excretion.Well Supported

Maintaining adequate testosterone levels may benefit from dietary strategies including saturated fat.

Not SupportedA ketogenic diet can decrease testosterone production and increase sex hormone binding globulin, leading to decreased free testosterone.

Well SupportedIncorporating desiccated organ capsules is an easy way to increase organ consumption and can improve how people feel and overall health.

Not SupportedPolyunsaturated fatty acids, such as omega-6 linoleic acid found in seed oils, can lower testosterone.

Not SupportedReductionist approaches to nutrition often fail to replicate the effects seen with whole foods due to the interplay of multiple nutrients.

Well SupportedLow-fat diets appear to decrease testosterone levels in men, but further randomized controlled trials are needed to confirm this effect.

Well SupportedA low-fiber, higher-fat diet resulted in better testosterone and estrogenic profiles in men.

Not SupportedA higher polyunsaturated fat to saturated fat ratio in the diet is associated with decreased serum testosterone.

Partially SupportedReversing insulin resistance to improve health involves eliminating seed oils and processed sugars, and consuming nutrient-rich foods like meat and saturated fats.

Partially SupportedA combination of a low-fat diet, seed oils, and high fiber is the best way to reduce testosterone.

Partially SupportedA high-fat, low-fiber diet in men reduced total testosterone and urinary excretion of estrogen and estradiol, while increasing urinary excretion of testosterone.

Partially SupportedCarbohydrates from fruit and honey signal abundance and are necessary for maintaining testosterone levels.

Partially SupportedVegan, vegetarian, and plant-based diets can be deficient in zinc, potentially decreasing total testosterone.

Partially SupportedMaintaining appropriate levels of sex hormones is important for both men and women.

Partially SupportedHealthy levels of sex hormones are associated with better mood, resilience, mental clarity, and emotional poise.

Not SupportedFiber is not an essential nutrient for health or regular bowel movements.

Partially SupportedDiets higher in saturated fat and lower in polyunsaturated fat and fiber are associated with higher androgen markers.

Partially SupportedA high-carbohydrate diet can increase plasma levels of testosterone and cortisol and their respective binding globulins in men.

Partially SupportedThe pervasive presence of seed oils in the modern diet correlates with a decline in men's testosterone levels.

Partially SupportedCurrent hunter-gatherer populations may not accurately represent the macronutrient ratios of historical human predecessors due to factors like megafauna availability.

Partially SupportedFurther randomized controlled trials are needed to confirm the effect of low-fat diets on decreasing testosterone levels in men.

Not SupportedExcessive fiber intake can negatively affect hormone levels.

Partially SupportedIn women, a low-fat diet for two months decreased levels of free estradiol and free testosterone, and lowered cholesterol.

Partially SupportedIn men with hypercholesterolemia, total testosterone levels are often lower, which may be linked to insulin resistance.

Partially SupportedLow-fat diets did not show significant differences in luteinizing hormone or sex hormone binding globulin levels in men.

Not SupportedLow-fat and plant-based diets are a concern for maintaining proper sex hormone levels.

Partially SupportedDecreased luteinizing hormone excretion on low-fat diets suggests reduced testosterone production.

Partially SupportedReplacing animal fat (butter) with olive oil or argan oil increased total testosterone by 17.4% and 19.9% respectively in a study.

Partially SupportedStrict carnivore diets may cause a slight drop in testosterone in some individuals, but controlled studies suggest this is not a reproducible phenomenon.

Partially SupportedExogenous arachidonic acid increases testosterone production in Leydig cells in vitro.

Partially SupportedIn overweight and obese men with insulin resistance, weight loss improves testosterone, SHBG, and sexual function.

Partially SupportedThe effects of nutrients like arachidonic acid on testosterone may not be observable in reductionist supplementation studies but are present in whole foods and organ meats.

Partially SupportedArachidonic acid supplementation in men has not been found to affect total or free testosterone.

Partially SupportedLow testosterone is associated with negative health outcomes.

Not SupportedA low-fat diet in women is associated with decreased sex hormones and may lower cholesterol levels.

Partially SupportedA very high-fat, very low-carbohydrate ketogenic diet did not affect total testosterone and increased it significantly compared to a Western diet, while also increasing insulin in the Western group.

Partially SupportedPaleolithic ancestors likely had a high-fat intake and relied heavily on animal foods.
