The Claim

Among adults with a mean baseline BMI of 33.2 kg/m², low-carbohydrate diets are associated with small but persistent reductions in blood pressure, with mean differences of -1.7 mmHg in systolic and -1.0 mmHg in diastolic blood pressure at 12 months or longer.

What the research says

Supports is higher

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

Supports

Challenges

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

Eating fewer carbs might help lower blood pressure a little bit over time, especially in people who are overweight.

What the research says

1 study

  1. Study: Low carbohydrate diet and effects on weight, lipids and blood pressure: A systematic review and meta-analysis of randomized controlled trials

    The study looked at low-carb diets and found they led to small but lasting drops in blood pressure, just like the claim says.
