Angel9608's Losing Weight Wish

I wish to lose 20-25 pound this year. I have been a stay at home with my preemie for over a year now. Currently I am bigger than my heaviest pregnancy weight. I am currently 176 lbs. According to my doctor I should be 145 lbs. Personally, I've been that weight and didn't feel good or look to healthy. I'll fee good at 150.
