Weight loss and breastfeeding

Just curious if anyone else is having trouble losing weight while breastfeeding. All the hype is how much weight falls off while breastfeeding.... not true for me!!! I am now 6 month postpartum and I’m almost my pre pregnancy weight. However, i was over weight when I got pregnant. I have been watching what I eat, low carbs and low sugar. I also walk/run 2-3 miles 6 days a week. I would like to lose 10/20 pounds! Any suggestions for diet and exercise?
