Claimed 91% heart-death risk in a 2025 study
The description states that a major 2025 study claimed intermittent fasting raises cardiovascular death risk by 91 percent and that headlines reported this widely. It does not name the study, the population, the comparison or the study design. The video is described as asking what the research actually showed, with a section on a controversial 2024 study and another on what that study actually showed. The description alone cannot confirm the figure or how it was measured.

Controlled trials and fasting protocols in the description
The description lists sections explaining what intermittent fasting is and the different protocols, then what controlled trials say. It also names sections on longevity mechanisms of fasting, a debate between Sinclair and Attia on fasting, a protein problem, and meal timing and circadian biology. No trial results, participant numbers, outcomes or effect sizes appear in the description, so none can be reported here.
