Krieger says there's some truth to the saying "nine months on, nine months off." But if you gained more than the recommended 25-35 pounds, it could take a bit longer to look like "you" again. Hang in there!
"The bottom line is that each woman loses postpartum weight at her own pace," Krieger says. "ChooseMyPlate.gov has a great section on keeping track of how much and what foods you want to eat the most of (whole grains, lean protein, lots of water, fruits and veggies) so weight loss will come."
Krieger also warns against fad diets, which will not promote long-term weight loss. Even worse: crash dieting can deny your body of nutrients and delay healing after birth, and deprive your baby of critical calories and nutrients if you're breastfeeding, ACOG says.
"As long as the mom is eating enough calories from the above-mentioned food groups to ensure she consumes the vitamins and minerals necessary to promote healthy skin and weight loss/maintenance and includes a little fitness each day, she is not only being the healthiest mom, but she is role-modeling a healthy lifestyle for her children," Krieger says. And she'll look good doing it, too!
