35. Track Your Fiber
While most people are told to eat more fiber in order to help with weight loss effects, regulate blood sugar, or combat diabetes, but in this case, you need to be careful you don’t overdo it.
Too much fiber will cause a decrease in overall testosterone levels, making it harder to build lean muscle mass. This doesn’t mean to avoid it entirely – many fiber rich foods are testosterone boosters.
Just keep your daily level in check. Aim for 30 or so grams per day.
