Losing weight while breastfeeding

Has anyone lost a significant amount of weight while breast feeding? I plan to breast feed, because I feel it’s healthier for the baby.. but on a side note I was wondering about losing weight while breast feeding? I’ve heard it’s a thing.. was wondering how true it is?! And how significant the weight loss can be.. I’ve gained a lot of weight during this pregnancy and i was just wondering if weight loss will happen during breast feeding ?

NO I AM NOT BREAST FEEDING SIMPLY TO LOSE WEIGHT, I’ve always wanted to my entire life. Before I even heard about the losing weight part of it..
