The Claim

In overweight and obese adults, consuming a 4-week diet with 15% of energy from saturated fat primarily derived from dairy does not impair insulin sensitivity and does not alter plasma lipid and lipoprotein concentrations compared to a diet with 7% saturated fat, suggesting that moderate increases in dairy-based saturated fat do not negatively affect metabolic health in the short term.

Source: Diets high in protein or saturated fat do not affect insulin sensitivity or plasma concentrations of lipids and lipoproteins in overweight and obese adults.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

If you're overweight, eating more saturated fat from dairy — like cheese or butter — for a month probably won't hurt your blood sugar control or cholesterol levels compared to eating less of it.

In overweight and obese adults, a 4-week diet with 15% of energy from saturated fat (primarily from dairy) does not impair insulin sensitivity or alter plasma lipid and lipoprotein concentrations compared to 7% saturated fat, indicating that moderate increases in dairy-based saturated fat do not negatively affect metabolic health in the short term.

What the research says

1 study
  1. Study: Diets high in protein or saturated fat do not affect insulin sensitivity or plasma concentrations of lipids and lipoproteins in overweight and obese adults.

    The study looked at whether eating more saturated fat for a month affects health markers in overweight people, and found no negative effects—just like the claim says.
