Research suggests that fat cells — particularly abdominal fat cells — are biologically active. It's appropriate to think of fat as an endocrine organ or gland, producing hormones and other substances that can profoundly affect our health. Although scientists are still deciphering the roles of individual hormones, it's becoming clear that excess body fat, especially abdominal fat, disrupts the normal balance and functioning of these hormones.
» Solution: First, add some fiber and greens to your diet. Second, learn better technique with core-related exercises. (Oh wait, that's every exercise!) Your pushups, planks, crunches, squats, lifts, jumps and everything in between need to be mastered. You could be putting stress on the lower back or hip flexors instead of actually working the abs, and that will cause a small protrusion of the abdominals. Finally, incorporate short sets of weight training, like supersets.
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.
