Which type of food unleashes leptin in the body?

Oral glutamine: Digestive tract cannot absorb leptin, so even if you could find a food rich in leptin it wouldn't help - forget about finding foods rich in leptin. The body has to create it's own leptin. You want is for your body to respond to leptin more efficiently (ultimately resulting in lower leptin levels!). As you lose weight, leptin levels drop, because fat itself causes the body to produce more leptin.

Fat: Fat causes body to produce more leptin. Fish and pulses make body more efficient at processing leptin.
