Cold-Induced Gene Mutations & Obesity

Leptin is the most important hormone in the human body that controls metabolism and hence the risk for obesity.  Early evolution occurred primarily in warmer climates, which meant that metabolism was set to rapidly disperse heat to keep internal temperature within range.  This created a metabolic type that was used to having little food yet was very good at burning oxygen and calories to dispose of heat – a fast metabolizer.

As humans migrated to Northern climates genetic change was likely over time as it was more important to retain heat, a natural adaptation.  New genetic research shows that this indeed was the case.  Numerous genes are different in those whose ancestors came from more Northern climates, especially changes in the leptin receptors that increase the risk for obesity and heart disease.

While these changes were needed for survival in a colder climate, they are extremely irrelevant to living with central heat and having an over-abundance of food.  This clearly means the stronger your ancestry is linked to colder climates the more you are genetically predisposed to obesity, high blood pressure, high cholesterol, and heart disease.

Genetic predisposition is not written in stone.  However, it is a weak spot that is likely to manifest as a problem when tested by such abuse as over-consumption of food.  For such individuals following the Leptin Diet to the letter is vital, as there is no margin for error once problems start.  Dietary supplements to support healthy leptin function are also helpful.
