How does leptin affect obesity?

When the body is functioning properly, excess fat cells will produce leptin, which will trigger the hypothalamus to lower the appetite, allowing the body to dip into the fat stores to feed itself. Unfortunately, when someone is obese, that individual will have too much leptin in the blood.

How does leptin cause obesity?

The deficiency of leptin or leptin receptor in humans results in extreme obesity and implicates leptinmediated signaling in the regulation of food intake, energy expenditure, reproductive, thyroid and immune functions [2]. Level of leptin is positively correlated with fat mass, being increased in obesity [4,5].

How does leptin affect body weight?

Leptin circulates in blood and acts on the brain to regulate food intake and energy expenditure. When fat mass falls, plasma leptin levels fall, stimulating appetite and suppressing energy expenditure until fat mass is restored. When fat mass increases, leptin levels increase, suppressing appetite until weight is lost.

Could leptin be used to treat obesity?

Leptin therapy is useful in treating obesity related to congenital leptin deficiency. Leptin has been recently approved for lipodystrophy, which is a model for typical obesity. Typical obesity presents with leptin resistance but leptin may still be valuable after weight loss or in conjunction with other therapies.

Is there a supplement for leptin?

Because leptin is a digestible protein that doesn’t enter the bloodstream, it can’t be taken in supplement form, Atkinson says. “If you were to take it as a pill, it’s just like eating chicken or beef. It’s a protein and your body would just break it up, so you wouldn’t absorb it from a pill.”

People with obesity tend to be resistant to the effects of leptin. Consuming anti-inflammatory foods, exercising and getting enough sleep may improve leptin sensitivity.

Does leptin cause weight gain?

Leptin also travels through your nervous system, stimulating fatty tissue to burn off fat and calories. If too much leptin builds up in your blood, you may develop leptin resistance. When this occurs, the leptin in your body may not do its job effectively, resulting in weight gain.
