Time-restricted eating is a dietary pattern that restricts the time during which a person eats to a specific window, such as a “16:8" pattern, where they fast for 16 hours a day and consume food only during the remaining eight hours. Evidence suggests that time-restricted eating improves cognitive function, supports weight loss, and reduces systemic inflammation. Findings from a recent review and meta-analysis suggest that time-restricted eating also reduces the risk of cardiovascular disease.

Researchers analyzed the findings of 33 studies involving 1,725 participants investigating the effects of time-restricted eating on markers of cardiovascular health. They conducted a sub-group analysis to determine how age, health characteristics, and eating patterns influenced the effects of time-restricted eating.

They found that the effects of time-restricted eating on cardiovascular disease varied according to a person’s risk factors, age, and when they ate. The table below presents their findings for the optimal time-restricted eating for different groups.

This meta-analysis and review identifies the optimal time-restricted eating interventions for blood pressure, obesity, lipids, and glucose. It effectively provides a best-practices guide for people interested in implementing time-restricted eating as a lifestyle modification to improve cardiovascular health.
