Weight Gain and Aging: An explanation and solution
Good info on this depressing topic.
Aging is characterized by changes in body composition. CT studies demonstrate that as we age, subcutaneous fat (below the skin, SF) decreases and visceral fat (in abdominal cavity, VF) increases. VF is the enemy. Because it causes systemic inflammation, it is an independent risk factor for coronary artery disease, stroke and death. If that’s not enough, VF also provides the Buddha-belly mid-life midriff.
The other most common age-related change in body composition is muscle loss. Because muscle has a high metabolic rate, its loss is associated with a reduction in energy expenditure. This decrease in caloric burn lends itself to weight (fat) gain.
