Ginger slightly raised a hunger hormone called ghrelin after eating, but this wasn’t strong enough to be certain, and it didn’t change the active form of the hormone.

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.

Women with more of the hunger hormone ghrelin tend to burn fewer calories at rest and after eating, even when you account for their body size and insulin levels.

After losing weight, people on very low-carb diets have higher levels of the hunger hormone ghrelin than those on high-carb diets, which might make them feel hungrier.

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.

One dose of ginger didn’t change blood sugar, insulin, fat levels, or inflammation markers after a meal in overweight men.
