Why Do We Eat When We’re Not Hungry?

Obesity is at an all-time high in the United States. Part of the reason why so many people are overweight and obese is that we tend to overeat, even when we aren’t hungry. In the last blog, we told you about grehlin, which is a hunger stimulating hormone.

Another hormone that regulates food intake is leptin, which tells your brain when you have had enough to eat.. For more than 50,000 years, humans relied on leptin to send signals to the brain to regulate what we ate. If the brain isn’t able to accurately read the messages that leptin sends it, you continue to feel hungry.

Eating too much sugar hinders our brain’s ability to read l¬¬eptin messages. Excess sugar calories are stored as fat, which releases leptin. The chronic elevation in leptin levels eventually leads to leptin resistance. As a result, the brain continues to send you hunger signals, even when you have had enough food.

Additionally, eating sugar triggers the production of your brain’s natural opioids, a key initiator of addiction. Essentially your brain becomes addicted to the sugar-induced opioid release. The abnormally high stimulation of your brain’s pleasure receptors by a sugar-rich diet generates excessive reward signals and overrides normal self-control mechanisms.

Limiting sugar intake is the one of the most effective way to stop overeating.
