The Claim

In overweight and obese adults consuming a weight-maintenance diet for 4 weeks, increasing protein intake from 20% to 30% of total energy or increasing saturated fat intake from 7% to 15% of total energy does not impair insulin sensitivity, plasma insulin levels, or lipid and lipoprotein concentrations, suggesting that short-term consumption of higher dairy-based protein or saturated fat does not adversely affect metabolic health in this population.

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.

Challenges

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
1 study reviewed
In plain English

If you're overweight or obese and eat the same number of calories, boosting protein or saturated fat from dairy for a month doesn't seem to hurt your blood sugar control or cholesterol levels.

  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 what happens when overweight adults eat more protein or saturated fat for a month, and found it didn’t harm their blood sugar or cholesterol levels.
