The underlying theory of blood type diets is that people with different blood types digest lectins differently, and that if people eat food that is not compatible with their blood type, they will experience many health problems.
Leptin is a potent stimulator of the immune system. Leptin receptors on monocytes cause the release intracellularly of STAT3 which cause the monocytes to release IL-6, IL-12 and TNF alpha. The IL-6 goes to the liver and increases production of CRP.
Research on leptin describes it as a hormone that plays a pivotal role in regulating food intake and energy output. Some researchers suggest leptin is our starvation hormone - rather than our obesity hormone.Leptin is a protein that's made in the fat cells, circulates in the bloodstream and goes to the brain.eptin resistance occurs when your leptin is high and you are overweight, but your brain cannot see it. In other words, your brain is starved while your body is obese. Some researchers have referred to this as brain starvation.
