Leptin is a hormone that helps regulate hunger and overeating. Certain foods, such as fructose and refined sugar, can reduce leptin sensitivity and increase the hunger hormone grehlin. While leptin is not the sole cause of obesity, it is an important factor to consider in weight loss.
The problem in society known as obesity has led many researchers and scientists around the world to speculate about the real causes of obesity. Many researchers have studied leptin and obesity, as leptin is a primary hormone that helps keep the body from consuming too much food. Changes in this hormone or a deviation from its proper function can give rise to overeating. Certain compounds and ingredients in common foods have been shown to reduce leptin sensitivity, such as fructose and refined sugar.
Leptin and obesity are an interesting topic of study because it involves a hormone that works to maintain homeostasis within the body at all times. Leptin is a hormone produced by the brain that tells the body that it no longer needs to receive any more food and then sends these signals to the stomach, which the individual interprets as full. Sometimes the brain makes a mistake, leading to overeating because the feeling of fullness never comes. Hormonal imbalances are one of the major theories behind what causes obesity and it has grown to include many studies that focus on certain foods that many reduce leptin productivity.
There has been some research into certain ingredients and foods that can discourage proper leptin signaling in the brain, thus leading an individual to overeat in an attempt to satisfy perceived hunger. When leptin is not present, the hunger hormone grehlin will make the body feel hungry and tell the brain it needs food. Some foods that have been shown to reduce leptin and increase grehlin are fructose and refined sugars. Fructose, a monosaccharide, is very problematic as it will also raise triglycerides and put your body at risk for heart disease later on.
Although leptin and obesity are strongly linked in a number of studies, the hormone is not perceived as the leading cause of uncontrolled weight gain or obesity. Rather, improper leptin signaling is seen as an important factor that may be acting in conjunction with other important factors driving the condition. Studies using large-scale analyzes that combine all known major factors can lead to a conclusion about the actual cause of overweight problems. It’s safe to say, however, that leptin and obesity are strongly related and are important factors to consider when dealing with weight loss or eating issues.
