Mostly True

A natural compound in grapes may reduce fat storage and increase fat cell breakdown.

Infact verdict: Mostly True (61/100).

The claims about a natural compound in grapes affecting fat storage and breakdown are supported by research on pterostilbene, a compound found in grapes and other berries. Multiple sources, including WebMD and research from Japan, suggest that pterostilbene may help reduce fat storage and increase fat breakdown in cells. However, these findings are primarily based on studies involving mouse cells, which may not directly translate to humans. The evidence is promising but not conclusive for human health benefits.
