The Claim

Fructose-sweetened beverages cause greater increases in visceral adiposity compared to glucose-sweetened beverages in overweight adults over a 10-week period, while glucose-sweetened beverages result in greater increases in subcutaneous fat, despite equivalent total weight gain.

Cause and effect
1 study reviewed
In plain English

Over 10 weeks, drinks sweetened with fructose lead to more fat accumulation around internal organs than drinks sweetened with glucose in overweight adults, while glucose-sweetened drinks lead to more fat under the skin, even when total weight gain is the same.

See the scientific wording

Fructose-sweetened beverages increase visceral adiposity more than glucose-sweetened beverages in overweight adults over 10 weeks, while glucose-sweetened beverages primarily increase subcutaneous fat, despite equal total weight gain.

Why this might work

When fructose is consumed, the liver converts it into fat more efficiently than glucose. This fat is packaged into particles that circulate in the blood and get deposited around internal organs instead of under the skin. At the same time, the body's ability to break down and remove these fat particles from the blood is reduced, so they stay longer and build up in the abdomen.

What the research says

  1. Study: Dietary sugars: a fat difference.

    This study found that when overweight people drink drinks sweetened with fructose (like high-fructose corn syrup), they gain fat around their organs, which is dangerous. But when they drink the same amount of calories from glucose, they gain fat under the skin instead—even though they gain the same total weight.
