The Claim

In firefighters with elevated baseline fasting glucose (≥100 mg/dL), a 12-week time-restricted eating intervention reduced fasting glucose by 6.00 mg/dL and HOMA-IR by 0.49 compared to controls, indicating improved insulin sensitivity.

In plain English

Among firefighters with high fasting blood sugar, a 12-week time-restricted eating schedule lowered fasting blood sugar by 6.00 mg/dL and reduced a measure of insulin resistance by 0.49 compared to those who did not change their eating pattern.

See the scientific wording

In firefighters with elevated baseline fasting glucose (≥100 mg/dL), a 12-week time-restricted eating intervention reduced fasting glucose by 6.00 mg/dL and HOMA-IR by 0.49, indicating improved insulin sensitivity, though not significantly different from controls.

Why this might work

When eating is limited to a 10-hour window each day, the body's internal clock resets, allowing the liver, muscles, and fat tissue to process sugar more efficiently. This reduces the amount of sugar in the blood and makes insulin work better, even without losing weight.

  1. Study: Feasibility of Time-Restricted Eating and Impacts on Cardiometabolic Health in 24-Hour Shift Workers: The Healthy Heroes Randomized Clinical Trial

    Firefighters who ate all their meals within a 10-hour window saw their long-term blood sugar levels drop significantly, even without losing weight — meaning their bodies handled sugar better. The study shows this worked better than doing nothing, contrary to what the claim suggests.
