Decreasing monounsaturated and saturated fat while increasing polyunsaturated fat intake, keeping total fat stable, decreased total testosterone by 15% in one study.

“More unsaturated fats lower testosterone in men.”

“More unsaturated fats lower testosterone in men.”

“there was a 38 drop in total testosterone uh on average there was a 37 drop in free testosterone there was a 30 drop in dihydrotestosterone”

“a similar but ineligible study found that decreasing monounsaturated fat and saturated fat while increasing polyunsaturated fat keeping total fat intake stable decreased total testosterone by 15”

“when the guys transferred from the high fat diet to the low fat diet their testosterone decreased by about 11.5 on average”

“we did a subgroup analysis where we took one study out that was an outlier probably for ethnicity and we just focused on the ones at the western man of european descent so it was ethnically homogenous and that had a larger decrease in testosterone that was 15”

“polyunsaturated fatty acids lowered testosterone”

“so one of the reasons that your testosterone could be low is you're not getting enough saturated fat you're getting too much polyunsaturated fat or you're eating too much fiber”

“the more saturated fat you have per day the more your testosterone goes up”

“saturated fat pretty clear r squared is 0.59 the more saturated fat you have per day the more your testosterone goes up the more monounsaturated fat you have per day okay more testosterone goes up”

“polyunsaturated fat to saturated fat ratio as the amount of poly polyunsaturated fat increases right you get a bigger number here serum testosterone goes down r squared is 0.39”

“There is a metaanalysis looking at fat types, and higher saturated fat diets were associated with more testosterone.”
