Weightloss and breastfeeding

Hey everyone! My baby girl is 8 weeks old tomorrow and I’m wondering if anyone has tried to lose weight at this time while breastfeeding and if it lowered milk supply?

I have 2 other children and I am the biggest size I have been. Family keep telling me to be patient as it’s still early postpartum but I think the sooner I start to try lose weight the better.

I’m thinking of being in a slight calorie deficit to lose weight slowly and healthily. Not sure whether this will impact my milk supply negatively. Any advice will be greatly appreciated❤️

Thanks in advance x
