The pre-pregnancy weight management program (Phases 2A, 2B and 2C) is designed to facilitate personalized weight loss goals using lifestyle behaviors that include, exercise, diet and behavioral modification. The intervention includes a "toolbox" concept to help meet weight loss goals. The Lifestyle Coaches will provide personalized instruction on physical activity/exercise. Participants randomized to the Control group will receive information on post-pregnancy diet/weight loss from the nutritionist as distinct from the LIPP nutritionist to decrease cross contamination between groups.
