Study Arms (2)

Three Meal

Behavioral: Eating Frequency

Grazing

EXPERIMENTAL

Participants in the increased eating frequency condition will be instructed to eat \> 100 kcals every 2-3 hours.

Behavioral: Eating Frequency

Interventions

Eating Frequency BEHAVIORAL

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).

Grazing; Three Meal
