Does wine make you fat?
Quick answer
A 150 ml glass of wine contains roughly 80 to 130 kcal depending on the type and alcohol level. Wine alone does not make you gain weight — excess overall calories and the snacking that often accompanies drinking are the real culprits.
Detailed answer
Wine is a caloric beverage, but its calories come mainly from alcohol (7 kcal per gram of ethanol) and, to a lesser extent, residual sugar. A standard 150 ml glass of red wine at 13.5% ABV delivers about 120 kcal — roughly half a banana.
The body prioritises metabolising alcohol, which temporarily slows fat burning. A study in the American Journal of Clinical Nutrition (Suter et al., 1992) showed ethanol reduces lipid oxidation by nearly 30% in the hours following consumption.
However, cohort studies paint a nuanced picture. The EPIC study (European Prospective Investigation into Cancer and Nutrition, 2009, over 370,000 participants) found that moderate wine consumption was not significantly linked to long-term weight gain in women, and the association was weak in men.
The real trap is aperitif snacking: cheese, charcuterie, and crisps consumed alongside wine can easily add 300 to 500 extra kcal. That combination, rather than wine alone, drives weight gain.
To minimise caloric impact: choose dry wines (under 4 g/L residual sugar), stick to standard pours (150 ml), and avoid mindless snacking during aperitif hour.
