Time-restricted eating leads to improved metabolic health outcomes compared to usual dietary patterns.

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

People who ate all their food before 1 p.m. had better blood sugar, insulin, and blood pressure than those who ate later or anytime — even though everyone lost about the same weight. This means when you eat matters, not just how much.

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 only during a narrow window in the morning and early afternoon lost similar weight as others, but they also had better blood sugar, less body fat, lower blood pressure, and a younger 'metabolic age' than those who ate later or just ate less. This suggests eating earlier in the day helps your metabolism work better.

Study: Effects of early, late and self-selected time-restricted eating on visceral adipose tissue and cardiometabolic health in participants with overweight or obesity: a randomized controlled trial

People who ate only during an 8-hour window didn't lose more belly fat or improve their blood sugar any better than people who just ate a healthy Mediterranean diet. So, eating at specific times didn't help more than just eating well.

Study: Calorie Restriction with or without Time-Restricted Eating in Weight Loss.

People who ate only between 8 a.m. and 4 p.m. didn’t lose more weight or improve their metabolism any better than people who ate the same number of calories anytime during the day. So, limiting eating hours didn’t help more than just eating less.
