The Claim

In adults with type 2 diabetes, reducing dietary carbohydrate intake from a baseline of 32% to 18% of total energy over 3 months is associated with a mean reduction in HbA1c of 1.0 percentage points (95% CI: −1.3 to −0.7), with greater carbohydrate restriction linked to larger reductions in HbA1c, suggesting that lowering carbohydrate intake may improve glycaemic control.

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.

In plain English

If adults with type 2 diabetes eat fewer carbs—dropping from about a third to less than a fifth of their daily calories for three months—they might see their average blood sugar drop by a full point, and the more they cut carbs, the better their blood sugar control tends to get.

See the scientific wording

Adults with type 2 diabetes who reduce their dietary carbohydrate intake to 18% of total energy from a baseline of 32% over 3 months experience a mean reduction in HbA1c of 1.0 percentage points (95% CI: −1.3 to −0.7), with greater carbohydrate restriction associated with larger HbA1c reductions, suggesting that lowering carbohydrate intake may support improved glycaemic control.

  1. Study: mHealth low carbohydrate dietary intervention ameliorates glycaemic profile, blood pressure and weight status in people with type 2 diabetes

    The study looked at people with type 2 diabetes who used an app to eat fewer carbs, and they ended up with much better blood sugar levels after 3 months—just like the claim says.
