Arm && Interventions

Group	Intervention	Description
High fiber	High fiber diet	Women in high fiber group will receive education on consuming a high fiber diet, including weekly lessons and daily snacks.

Primary Outcome Measures

Name	Time	Method
Maternal Weight Changes	Baseline through 2-mounths postpartum	Assess weight change between groups
Maternal Fat Accretion Changes	Baseline through 2-mounths postpartum	Assess fat accretion change between groups using the Selinger four-compartment model
Identify Changes in Fiber Intake	Baseline through 2-months postpartum	Compare fiber intake between groups by using 24-hour dietary recalls
Identify Changes in Dietary Quality	Baseline through 2-months postpartum	Compare dietary quality between groups using the Alternative Healthy Eating Index (AHEI) scoring ranges from 0 to 100 (higher score means a better diet quality).

Secondary Outcome Measures

Name	Time	Method
Maternal Weight	2-months through 12-months postpartum	Assess weight change
Infant Fat Accrual	Birth to 12-month old	Identify differences in early infant fat accrual between group by completing body composition measurements including but not limited to Dual energy x-ray absorptiometry (DXA) and PeaPod
Maternal Fat Accretion	2-months through 12-months postpartum	Assess fat accretion change between groups using the Selinger four-compartment model
Dietary Fiber Intake	2-months through 12-months postpartum	Assess differences using 24h recalls
Dietary Quality	2-months through 12-months postpartum	Compare dietary quality between groups using the Alternative Healthy Eating Index (AHEI) scoring ranges from 0 to 100 (higher score means a better diet quality).
