The Claim
Body mass index (BMI) mediates approximately 30–36% of the association between shift work and metabolic dysfunction-associated steatotic liver disease (MASLD), indicating that weight gain is a significant but incomplete pathway through which shift work contributes to liver fat accumulation.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who work irregular shifts tend to gain weight, and that extra weight explains about a third of why they’re more likely to have fat in their liver—but other factors also play a role.

What the research says
1 studyThe study says shift work might lead to more liver fat partly because people gain weight, but it doesn’t say how much of that effect is due to weight gain — so it can’t confirm the claim that it’s exactly 30–36%.
