time-restricted eating 10h window improves cardiometabolic risk markers in shift workers firefighters
In plain terms: Does a 10-hour eating window help shift workers heart and metabolic health?
Promising in one decent randomized trial, but it is Panda's own lab, both arms were also nudged toward a Mediterranean diet, benefits were modest/subgroup-limited, and it has not been independently replicated.
Evidence ladder
How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."
Top evidence so far: Human trials (RCT / n-of-1)

| Source | Grade | Stance | Quality | Finding |
|---|---|---|---|---|
| Manoogian 2022 · Cell Metab | RCT | mixed | moderate | Panda-lab Healthy Heroes RCT (n=137 firefighters): TRE feasible, decreased VLDL size; HbA1c/diastolic-BP improvements only in the elevated-baseline-risk subgroup; both arms coached toward Mediterranean diet (confound). |
| Manoogian 2021 · BMJ Open | RCT | supports | low | Panda-lab protocol paper — design/rationale only, not outcome evidence; underscores single-lab origin of the claim. |
Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
