The Claim
In overweight and obese adults consuming a low saturated fat diet (7% of energy), a 4-week high-protein diet (30% of energy from protein, primarily whey) increases fasting glucose by 0.47 mmol/L compared to a moderate-protein diet (20% of energy), but this effect is not observed when saturated fat intake is high (15% of energy), indicating an interaction between dietary protein and saturated fat content on fasting glycemia.
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.
If you're overweight and eat a lot of protein—especially from whey—for a month, your blood sugar might go up a bit, but only if you're also eating very little saturated fat. If you eat more saturated fat, that same high-protein diet doesn't seem to affect your blood sugar.
See the scientific wording
In overweight and obese adults, a 4-week diet with 30% of energy from protein (primarily whey) compared to 20% increases fasting glucose by 0.47 mmol/L when saturated fat intake is low (7% of energy), but not when saturated fat is high (15% of energy), indicating an interaction between protein and fat content on fasting glycemia.
What the research says
1 studyThe study found that eating more protein raised blood sugar slightly, but only when people also ate less saturated fat — which matches what the claim says.
