The Claim

A 12-week low-carbohydrate energy-restricted diet in adults with type 2 diabetes and obesity reduces circulating fibroblast growth factor 21 (FGF21) by -161.2 pg/mL (p=0.035), suggesting normalization of hepatokine secretion patterns associated with improved metabolic health.

What the research says

Supports is higher

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

Challenges
0score

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

When people with type 2 diabetes and obesity follow a low-carb diet for 12 weeks, it lowers a specific protein in their blood that's linked to better health.

What the research says

1 study
  1. Study: A secondary analysis of indices of hepatic and beta cell function following 12 weeks of carbohydrate and energy restriction vs. free-living control in adults with type 2 diabetes

    The study tested the exact same diet as the claim and found that it lowered a specific hormone (FGF21) in people with diabetes and obesity, which matches what the claim says and suggests better health.
