Wanting to get back to the old me

Hi I'm Kc and I want to lose my pregnancy weight and slim down back to the old me cause I miss my four pack and everyone asking how I lost so much when I didn't try all I did was work out 5 times a day cause I thought it was fun. I since stopped that because of the questioning saying I was starving myself. Even tho they would watch me eat a Big Mac and a large fri right in front of them. But I got sick of the name calling and rumors that I stopped but now I'm lucky if I can go five times during a month.
