Weight loss might be more than just willpower.
It turns out that Leptin levels might be the key to understanding obesity and the challenge of weight loss.
Leptin is a hormone that controls hunger.
It’s what makes you feel “full” after eating. It is secreted by adipose tissue (fat tissue). If your leptin signaling is working properly, when your fat stores are “full,” this extra fat will cause a surge in your leptin level, which signals your brain to stop feeling hungry, to stop eating, to stop storing fat and to start burning some extra fat off.
Scientists have long recognized the connection between leptin and feelings of hunger. As the master of metabolism, leptin is on the lookout for how many calories—or how much energy—your body is taking in. It’s essential for maintaining energy balance.
Leptin is also tied closely to insulin resistance and metabolic syndrome. Scientists are just starting to understand the connection between leptin levels, type-2 diabetes and other metabolic disorders. One recent study proved for the first time that leptin levels can indicate your risk of heart disease.
Fixing leptin levels might be the hidden health secret that keeps people from developing heart disease, diabetes, or other metabolic disorders.
