Energy balance

Flexible time-restricted eating leads to a spontaneous reduction in total energy intake without altering macronutrient composition.

If you use an 8-hour eating window, you will likely eat fewer calories without needing to count them or change your food choices. This spontaneous reduction in energy intake is a key driver of the fat loss seen with flexible TRE.

The flexTRE group and combined group (flexTRE+EX) exhibited a larger reduction compared to the control group... at post-intervention... No significant group-by-time interaction effects were found in the macronutrient composition, including carbohydrates, protein, and fat percentage
