Here’s what you need to know…
- Leptin is a hormone that decreases the appetite, increases the metabolism, and leads to leanness.
- The human body only responds to leptin if leptin receptors are working properly and telling the brain that leptin is high.
- 30 seconds of intense exercise, like bike sprints, will increase leptin signaling. But it only works in the absence of the hormone insulin, which is produced after meals.
- Fasted sprinting has shown to increase leptin signaling.
