Losing weight, particularly by getting rid ofthe body’s fat stores, can be done by achieving a caloric deficit. This means having your body use more calories than what is available from your diet.
When undera caloric deficit, the body looks for additional sources of energy. And, with body fat being loaded with calories, the body would look to it as a source for the sustenance of metabolism.
As a result, the body loses fat and you get your desired physique.
A caloric deficit can be achieved in two ways: by eatingfewer calories or by having your body use more calories. But, regardless of how you’d go about to attain a caloric deficit, the body won’t be getting all the energy it needs from your diet – and as a result, it would have to slow down some processes.
Unfortunately, these processes include the production of testosterone, meaning your testosterone levels would eventually decrease. And, with dieting,you’ll have low testosterone levels for a prolonged period, which entails health issues like decreased strength, sexual dysfunction, and low libido.
In addition to having lowered testosterone levels, when the body is experiencing a caloric deficit, it’s actually under stress. This means the adrenal cortex would produce stress hormones like epinephrine, cortisol, and adrenaline.
And, because of these stress hormones, your testosterone levels will continue to drop – and the androgen fails to carry out its most important roles in managing behavior. Yes, hormones drive some of the most common behavioral characteristics associated with being a man.
Another process that’s slowed down by a caloric deficit is the production of hormones in the thyroid gland. Since the T3 and T4 hormones from it aid in the production of testosterone, it would cause T hormone levels to drop even further.
Of course, this does not mean that you should give up on losing weight or improving your physique. After all, men who have leaner physiques have significantly higher testosterone than males who have more body fat.
This just means that you’ll have to be smarter about achieving and maintaining a caloric deficit while, at the same time, making sure testosterone levels do not suffer.
