Brief Summary

A randomized controlled trial to determine the effectiveness of early time-restricted eating on muscle performance and body composition in active, resistance trained adults. Two parallel groups will be randomly assigned to either the early time-restricted eating or a control group. All participants will be asked to maintain their usual exercise routines during the 6 week intervention period. Muscle strength and endurance are the primary outcomes. Body composition (body weight, fat mass, fat-free mass and percent body fat), hunger and satiety ratings, sleep quality, energy intake, diet quality, macronutrient composition and adherence are secondary outcome measures.

Study Arms (2)

early time-restricted eating

EXPERIMENTAL

The Early Time Restricted Eating (eTRE) group will be asked to consume calorie containing food or drinks only between 9am to 5pm, daily. At other times they are to avoid consuming any calorie containing food or drinks.

Behavioral: early time restricted eating

Control

NO INTERVENTION

The Control group will follow their usual eating routine.

Interventions

early time restricted eating BEHAVIORAL

The intervention group will eat in a prescribed daily feeding window (9am-5pm) and follow their normal exercise and resistance training routines. We will allow up till +/-1 hour for the eating window start and end times while aiming for an 8 hour eating window.
