Scientists found that women with more of a hunger hormone called ghrelin tended to burn fewer calories at rest and after eating, and also ate less food.
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.

A daily caloric surplus of 64 kcal from reduced postprandial energy expenditure due to ultraprocessed food consumption results in approximately 1 pound of fat gain per month.
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.
Women with more ghrelin — the hunger hormone — actually eat less each day, which seems surprising but was observed in this group.
The hunger hormone ghrelin doesn’t seem to affect how the body burns fat vs. carbs after eating, how active someone is, how fit they are, or their eating habits like restraint or hunger feelings.
