Early time-restricted eating, when total caloric intake is matched, results in lower fasting glucose and lower diastolic blood pressure compared to late-time eating.

Study: Early time-restricted eating with energy restriction has a better effect on body fat mass, diastolic blood pressure, metabolic age and fasting glucose compared to late time-restricted eating with energy restriction and/or energy restriction alone: A 3-month randomized clinical trial.

This study found that people who ate all their meals earlier in the day had better blood sugar and lower blood pressure than those who ate the same amount of food later, even when both groups ate the same number of calories.

Study: Randomized controlled trial for time-restricted eating in overweight and obese young adults

When people eat all their food early in the day (like between 7 a.m. and 1 p.m.), their blood sugar drops more than when they eat the same amount of food later. This study shows early eating helps the body manage sugar better, and likely helps blood pressure too.

Study: Early time-restricted eating with energy restriction has a better effect on body fat mass, diastolic blood pressure, metabolic age and fasting glucose compared to late time-restricted eating with energy restriction and/or energy restriction alone: A 3-month randomized clinical trial.

People who ate all their meals earlier in the day, while eating the same total calories as others, ended up with better blood sugar and lower blood pressure than those who ate the same food later in the day.

Study: 1654-P: Effects of Acute Late Isocaloric Eating on 24-h Blood Glycemia in Adults with Overweight and Obesity

When people eat their meals later in the day — even if they eat the same amount of food — their blood sugar stays higher, especially at night. This suggests eating earlier helps keep blood sugar lower, which is good for health.
