Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Additionally, aerobic training performed in a fasted state appears to promote physiological adaptations that may improve the metabolic health in individuals with overweight and obesity.
The present study investigates the effects of 8 weeks of TRE associated with aerobic training in a fasted state versus a fed state on body composition and cardiometabolic parameters in women with overweight and grade 1 obesity.

Study Groups

Time-Restricted Eating and Aerobic Exercise Performed in Fasted State
Participants will be prescribed a diet plan to promote weight loss, but no food will be provided to them.
Diets will be formulated to contain 50% energy as carbohydrate, 20% as protein, and 30 % as fat.
Participants will be instructed to divide their daily energy intake between three meals each day (lunch, afternoon snack, and dinner).
Participants will be instructed to eat from 12.00 until 20.00 (8-hour window). Aerobic exercise sessions will be carried out during the morning shift with participants in a fasted state.
Dietary and Exercise Approaches
Intermittent fasting plus energy restriction combined with aerobic exercise performed in a fasted state.
Time-Restricted Eating and Aerobic Exercise Performed in Fed State
Participants will be prescribed a diet plan to promote weight loss, but no food will be provided to them.
Diets will be formulated to contain 50% energy as carbohydrate, 20% as protein, and 30 % as fat.
Participants will be instructed to divide their daily energy intake between three meals each day (lunch, afternoon snack, and dinner).
Participants will be instructed to eat from 12.00 until 20.00 (8-hour window). Aerobic exercise sessions will be carried out during the afternoon shift with participants in a fed state.
Dietary and Exercise Approaches
Intermittent fasting plus energy restriction combined with aerobic exercise performed in a fed state.
Time-Restricted Eating
Participants will be prescribed a diet plan to promote weight loss, but no food will be provided to them.
Diets will be formulated to contain 50% energy as carbohydrate, 20% as protein, and 30 % as fat.
Participants will be instructed to divide their daily energy intake between three meals each day (lunch, afternoon snack, and dinner).
Participants will be instructed to eat from 12.00 until 20.00 (8-hour window). Participants in this arm will not perform aerobic exercise training.
Dietary Approach
Intermittent fasting plus energy restriction without aerobic exercise training.
