Weight loss after baby

I was wondering if anyone who lost all their baby weight (or more) had any tips, or followed anyone for inspiration? I struggled with an eating disorder for years, i got healthy and I was comfortable with my body now I'm 4 months pregnant, I'm very exited about being pregnant but the weight gain is a little bit hard to except. I want to have a plan for after the baby is born, I am planning on breastfeeding I know some say that helps.
