The Effect of Time-Restricted Feeding on Anthropometry, Biochemical Parameters, Diet Quality and Eating Behavior

The goal of this randomized controlled trial is to to determine the effects of time-restricted feeding intervention on body weight, body composition, biochemical parameters and eating behaviors in overweight female individuals.The main questions it aims to answer are:Does time-restricted feeding intervention reduce daily energy intake?Does time-restricted dietary intervention result in body weight and body fat loss?Does time-limited nutritional intervention lead to improvements in biochemical parameters?Does time-restricted feeding intervention improve eating behavior and eating awareness?Does time-restricted feeding intervention adversely affect diet quality?The participants in the intervention group will receive a time restricted feeding intervention (first meal at 10:00, last meal at 18:00) for 6 weeks. Meals of the participants are planned as 8 hours of eating and 16 hours of fasting.Participants in the control group will not receive any dietary intervention.
