Research has shown that energy balance a dysregulation, which is central to obesity, is closely linked to the aging process. Studies have repeatedly shown that the factors that most often correlate with telomere length in humans are metabolic parameters, including BMI (body mass index), fasting blood glucose and insulin levels. Just as important, many of the molecular signaling pathways that are known to be involved in cellular aging, including insulin, mTor, and estrogen, are also involved in mainting a healthy metabolism.

Aging and obesity are closely linked, and “brown fat” may be the connection between the two.
