In men, adequate levels of testosterone are necessary to maintain a healthy fat distribution. However, research has shown that the presence of visceral fat can interfere with testosterone production, further exacerbating the storage of fat in the belly. Excess abdominal fat not only reduces testosterone production, but is also associated with a rise in the female hormone estradiol in men. It is unclear if testosterone decline associated with aging disrupts the production of testosterone, or if the accumulation of fat via weight gain leads to lower levels of testosterone. Either way, the reduction of visceral fat via lifestyle changes is beneficial for overall health in men.
Does the body type theory work in these cases? Well, knowing that you’re a pear or an apple is useful for identifying those exercises that can help you achieve a more proportionate appearance, but focusing more on the upper body or on the legs might not be effective in reducing the belly fat. So today we’ll talk about the Belly type theory, launched by chiropractor Eric Berg, author of a book called The 7 Principles of Fat Burning.
