Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking open label
Primary purpose treatment
Arm
(Experimental)
Participants in this condition will be instructed to limit their number of eating frequency to three meals per day.
eating frequency
Thirty adults will be provided an 8-week standard lifestyle intervention, that includes a 1200-1500 kcal/day, < 30% energy from fat dietary prescription, and a physical activity goal of 200 minutes/week. Participants will be randomized to one of two conditions differing in EF using a prescription we have tested previously. One condition will limit the number of eating bouts/day to three (Three Meal), while the second condition will consume at least 100 kcal every 2 to 3 hours which should lead to approximately 6 eating bouts/day (Grazing).
(Experimental)
Participants in the increased eating frequency condition will be instructed to eat > 100 kcals every 2-3 hours.

Additional Information

Official title Healthy Eating Patterns During a Lifestyle Intervention
Principal investigator Hollie A Raynor, PhD, RD
Description Little intervention research has been conducted to examine the influence of eating frequency (EF) on weight loss. It has been hypothesized an increased EF improves appetite control, assisting with better regulation of energy intake, thus decreasing body mass index. Unfortunately, outcomes have not shown greater appetite control with increased EF. Instead, trends favor a lower EF reducing energy intake thereby producing greater weight loss than a higher eating frequency. Thus, a lower eating frequency may lower energy intake via behavioral mechanisms. At thit time no research has examined the behavioral mechanisms that may mediate the relationship between a lower eating frequency and superior adherence to an energy-restricted diet.
