ELi5: Are calories from alcohol processed differently to calories from carbs/sugar?

626 views

I’m trying to lose weight and occasionally have 1-3 glasses of wine (fitting into my caloric intake of course). Just wanted to know if this would impact my weight any differently than if I ate the same calories of sugar. Don’t worry, I’m getting enough nutrition from the loads of veggies and meats and grains I eat the rest of the time.

Ethanol is transformed into acetaldehyde by the liver and then transformed into acetic acid by the liver too, but in a 2nd independant step. Acetic acid is a short chain fatty acid and it’s processed the same way as any fatty acid, but it circulates directly in the blood rather than being packaged in lipoproteins.

The calories from ethanol have the same effect on your weight than any other calories (and it’s about 7 Cal per gram vs 4 for carbonydrates and 9 for fatty acid). You get to have also the psychoactive effects of alcohol and the highly toxic effects of acetaldehyde though, which you don’t get if you take sugar or fat.
