Leptin signals to the brain, in particular to an area called the hypothalamus. Leptin does not affect food intake from meal to meal but, instead, acts to alter food intake and control energy expenditure over the long term. Leptin has a more profound effect when we lose weight and levels of the hormone fall.
Considering this, what foods is leptin in?
High carbohydrate foods that contain simple starches like white flour and potatoes, along with highly processed foods containing sugar and high-fructose corn syrup, all contribute to decreased leptin sensitivity. Eating large meals or eating too frequently can also lead to a decrease in leptin sensitivity.
What stimulates leptin?
Leptin also boosts metabolism to help regulate body weight. The hormone is secreted from your fat cells, and levels are correlated with body fat percentage. When body fat levels fall, leptin levels decrease and appetite is stimulated; when fat mass rises, the opposite occurs.
What role does leptin play in hunger?
Well, let me introduce you to some hormones that do just those things: the "hunger hormones," leptin and ghrelin. Leptin is a hormone, made by fat cells, that decreases your appetite. Ghrelin is a hormone that increases appetite, and also plays a role in body weight.
