You all heard it. Loads of protein. Skyrocketing testosterone levels. Sounds perfect for your bodybuilding goals? Yeah, right. You need to consume lots of protein if you’re packing on serious muscle. Likewise, you also have to engage yourself to some T-level-surging programs or diet plans in order to get those muscles swelling. Ironically, these two superpowers are not great partners.

To shed light to the conventional wisdom that more protein intake equals more muscle gains, let us study how its interaction with testosterone affects your muscle gains in the process.

It is totally fine if you are into carb back-loading. That macronutrient-based diet is as effective as the other methods. What I am bringing to the table this time is your high-protein obsession that actually contradicts your aim of boosting your testosterone production.

It has been discussed many times that the principle of the male hormone, testosterone, is what gives men the amount of muscle they have compared to women. This concept, too, describes how some individuals who resort to synthetic testosterone drugs build excessive muscle mass. However, an important note that most of us tend to overlook is how highly responsive this hormone is to various lifestyle factors. And this does not exclude the amount of protein you consume on a daily basis.

According to factual assertions, excessive protein consumption is detrimental for testosterone production.

Here are some facts which back up this assumption:

  1.  Spare your body the difficulty of going through the digestion process. Admittedly, protein is not an easy nutrient to digest. So if you take too much of it, your body goes under stress, thus increasing the cortisol level. This stress hormone is known to decrease your T levels.
  2.  An increased sex hormone binding globulin (SHBG) in the body can as well contribute to lowered T levels. Too much protein can cause the rise of SHBG in the bloodstream as it binds to almost sixty percent of the body’s free testosterone. When this happens, the bound testosterone becomes unusable.
  3.  Another thing which interferes with your T-boosters is the insulin-like growth factor that spikes when you consume excessive amounts of protein. This finding is not conclusive, but it still seems unlikely that the high protein diet can lead to more testosterone.
  4.  There is no strong evidence to support the claim that higher protein portions from the extra calories have a significant impact on increasing your T levels. This is despite the 2008 findings that high intensity exercise plus high-calorie consumption are linked to testosterone boost.
  5.  When you take in too much of one macronutrient, you tend to compromise the amounts of the other two – carbohydrates and fats. According to studies, fats and carbohydrates have shown positive effects in improving testosterone levels and are more important components in maintaining balance in the body than protein.
