I am overweight (40+ lbs over normal healthy) and am 15 weeks pregnant. I have already gained 10 lbs with this pregnancy. To keep my weight gain at the 15-20 lb range for overweight women, I planned to eat healthy meals during the day, from 9 am to 4-5pm but then not eat after 4-5pm (a time when I tend to make bad choices and overeat anyway). Since I have so much extra fat, is it okay for the baby if I go that stretch of 16-17 hours overnight without eating? I am consuming a healthy amount of calories, enough to maintain and not lose weight, during the day.
