Review: Meal Timing, Circadian Clocks and Healthy Aging
This abstract describes a review of chrononutrition: how meal timing interacts with circadian rhythms and metabolism. It reports that aligning food intake with internal rhythms may improve metabolic markers, often without weight loss, and may affect aging-related processes. Long-term effects remain unclear. [1]

The key findings
The review links rising obesity, type 2 diabetes, cardiovascular disease and age-related disorders to a growing mismatch between modern lifestyles and biological rhythms. [1]
The review gives particular attention to Time-Restricted Eating and related meal-timing interventions. [1]
Current evidence is said to indicate that aligning food intake with circadian rhythms improves several metabolic markers, often independently of weight loss. [1]

Mismatch between modern lifestyles and body rhythms
The review starts from a reported rise in obesity, type 2 diabetes, cardiovascular disease and age-related disorders. The authors link this to a growing mismatch between modern lifestyles and the biological rhythms that regulate human physiology. Chrononutrition is presented as a promising strategy to improve metabolic health and support healthy aging. The abstract does not give numbers or describe specific studies behind these statements.

Light, sleep, activity and time-restricted eating
The review examines the molecular and physiological basis of chrononutrition, including the interplay of central and peripheral circadian clocks, metabolic regulation and aging processes. It discusses environmental and behavioural zeitgebers — cues such as light exposure, feeding schedules, sleep and physical activity — that help keep circadian alignment and metabolic balance. Particular attention goes to Time-Restricted Eating (TRE), a meal-timing approach, and related interventions. The abstract does not report how many studies were included or how they were selected.

Reported metabolic benefits and proposed aging mechanisms
According to the abstract, current evidence indicates that aligning food intake with endogenous circadian rhythms improves insulin sensitivity, metabolic flexibility, lipid metabolism, blood pressure regulation and inflammatory balance, often independently of weight loss. Mechanistically, chrononutrition may also modulate processes associated with aging, including mitochondrial function, autophagy, nutrient sensing, oxidative stress and inflammaging. These are described as possible mechanisms, not proven causes. The authors call for future studies on long-term effects on biological aging, resilience and healthy longevity, and on personalized interventions based on circadian phenotypes.

How to interpret this
This is an abstract only; the full text was not reviewed. The abstract reports no study numbers, sample sizes, follow-up or effect sizes. Statements about metabolic benefits and aging mechanisms are presented as review-level evidence and possibilities, not proven causal effects. Long-term effects on biological aging and longevity are explicitly described as still to be clarified.
