How diet changes hunger hormone and health in people with belly fat
Diet-induced fasting ghrelin elevation reflects the recovery of insulin sensitivity and visceral adiposity regression.

This study looked at how different diets affect a hunger hormone called ghrelin in people with belly fat. After 18 months, the green-MED diet (with green tea and a plant shake) led to the biggest rise in ghrelin, and higher ghrelin was linked to better blood sugar control and less belly fat in men....
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Visceral fat is metabolically active tissue that releases cytokines, which impair insulin sensitivity and disrupt metabolic signaling in the liver, muscles, and brain, leading to systemic metabolic dysfunction.
People with more belly fat and metabolic issues tend to have lower levels of a hunger hormone called ghrelin, which is linked to higher fat in the liver, more leptin (a fullness hormone), and higher blood pressure.
After following different diets for 18 months, people who ate a green-MED diet (with extra plant-based shakes and green tea) had a bigger increase in their hunger hormone levels compared to those on standard healthy eating guidelines.
In men with excess belly fat and metabolic issues, a rise in hunger hormone levels was linked to better blood sugar control, higher 'good' cholesterol, and reduced belly fat, even after accounting for how much weight they lost.
After following diets for 18 months, men's hunger hormone levels went up slightly while women's went down, showing a clear gender difference in how the body responds to dieting.
