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.
First one’s the Adrenal belly or Adrenal shape, caused by increased levels of cortisol. When going through stressful periods, the production of cortisol increases, and this favours the accumulation of fat around the waist, leading to a saggy abdomen. Both men and women are likely to gain weight around the waist if they are constantly exposed to high levels of stress, and besides the excess belly fat, they are also likely to experience fatigue, back pain, nervousness, poor memory and sleep problems.
