Time-restricted eating, metabolic health and organ-specific biological age indices
In a cross-sectional survey of 4,890 people, metabolic dysfunction and obesity were associated with higher organ-specific biological age indices and poorer cardiovascular health; moderate eating frequency and fasting durations were associated with lower indices. [1]

Survey data on eating timing and organ age indices
This cross-sectional study used National Health and Nutrition Examination Survey data from 2003 to 2018, covering 4,890 participants. Time-restricted eating strategies were assessed from eating frequency and meal timing. The researchers evaluated indices of organ-specific biological age for heart, kidney, liver and overall, plus a frailty index, Life's Essential 8 and a cardiometabolic index. Because the design is cross-sectional, it captures associations at one point rather than changes over time.

Metabolic dysfunction linked to higher organ age indices
Metabolic dysfunction and obesity were associated with elevated indices of organ-specific biological age and impaired cardiovascular health. Metabolic dysfunction status was related to more rapid advancement of cardiovascular biological age indices. Excessively long or short fasting durations were associated with a decline in indices of liver metabolic health and worsened cardiovascular risk markers. Moderate eating frequencies and fasting durations were associated with lower biological age indices and better health metrics across subgroups. The link between better cardiovascular health and healthy metabolism was more pronounced in people who ate breakfast on time.

Abstract-only scope and proposed personalized approach
The authors describe an independent relationship of metabolic dysfunction and obesity with advancement in organ-specific biological age indices and impaired cardiovascular health metrics. They also highlight a potential role for personalized time-restricted eating in relation to modulated biological age indices across different metabolic health and obesity statuses. This is framed as a potential role, not a demonstrated effect. Only the abstract was reviewed; the full text was not reviewed, so details of measurement, adjustment and analysis remain unclear.
