The Claim

In adults with atherogenic dyslipidemia, a 12-week hypocaloric carbohydrate-restricted diet (12% carbohydrate, 59% fat, 28% protein) results in greater reductions in fasting insulin (−50%) and glucose (−12%) and greater improvement in insulin sensitivity (−55%) compared to a hypocaloric low-fat diet (56% carbohydrate, 24% fat, 20% protein), indicating that carbohydrate restriction may be more effective for improving glycemic control in this population.

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

For adults with a certain type of unhealthy cholesterol and blood sugar issues, cutting carbs way down for 12 weeks might lower insulin and blood sugar more than a low-fat diet — meaning it could help control blood sugar better.

  1. Study: Carbohydrate Restriction has a More Favorable Impact on the Metabolic Syndrome than a Low Fat Diet

    The study found that people with a certain type of cholesterol problem who ate fewer carbs had bigger drops in blood sugar and insulin than those who ate less fat, just like the claim says.
