However, wild fish tends to be ridiculously high in the beneficial anti-inflammatory omega-3 fatty acids with lower levels of the inflammatory omega-6’s… If you’re a frequent reader here, you already know that polyunsaturated fatty acids (PUFAs), are known for their testosterone lowering effect. Eating more whole foods, less processed goo, also provides you with a TON of essential micronutrients for testosterone synthesis. When you eliminate processed stuff, you most often also eliminate the testosterone lowering trans-fats, polyunsaturated fats, pesticides and possible man-made chemicals that act as endocrine disruptors. …Still, most of the "experts" in the field like to state various ratios for carbs, fats, and protein. The original study is slightly unclear, in that it implies all 10 drop-outs were from the treatment group, but does not explicitly state this. Different protein sources may have differential effects on TT, thus future research may also examine the effects of plant versus animal, and whole food versus powdered protein. Rodents fed protein 52% of TEI show kidney injury and increased systemic inflammation (Snelson et al., 2021); and fed protein 44% of TEI show increased markers of oxidative stress (Żebrowska et al., 2019). However, it should be mentioned that this is mostly theoretical at this point, as there are no direct studies examining this. Aging 10 years increases your odds of having low testosterone by 36%, but a 4-inch increase in waist size may increase your chances by up to 75%. If you're obese, you're four times more likely to benefit from testosterone replacement than non-obese men. By contrast, endurance exercises like cycling for hours or running marathons can actually reduce your testosterone level. Certain testosterone boosters have specific side effects. Vitamin D. Your body naturally produces vitamin D when your skin is exposed to sunlight. The aforementioned 4.4 g/kg/day study incurred a high dropout rate, however, the majority of the participants seemingly tolerated the diet; although side effects were not examined in detail (Antonio et al., 2014). The unmarked studies used a higher protein diet; although often including protein supplements as well. These studies used a protein vs carbohydrate supplement intervention, to increase protein intake. Change from baseline scores used where possible, and in these studies, the percentage change in testosterone was calculated using the starting value for diet one (Haun et al., 2018; Hoffman et al., 2007; Jaffe, 2013; Pourabbas et al., 2021; Toma, 2009; Volek et al., 2002). Indicator amino acid oxidation studies estimate this at ∼1.9 g/kg/day, which is again higher than nitrogen balance studies, and more similar to athlete population intakes (Bandegan et al., 2017, 2019; Jenner et al., 2019; Tarnopolsky et al., 1988). The proposed definition for a high-protein diet is an intake sufficient for the average athlete (estimated average requirement).
