Effect of long-term changes in diet and exercise on plasma leptin
Leptin is one of the newly discovered hormone that is related to weight control in the body. Adipose tissue produces most of the body’s leptin, and with high levels (as with insulin) it is believed that the body becomes resistant to the leptin, and it loses its ability to bring body weight down. This study shows that leptin levels are reduced by exercise. This is not a surprise, but adds further importance to the recommendation for exercise in any lifestyle improvement.
