Weight issues

Right after giving birth, i had issues breastfeeding our daughter. My supply wasn’t building right so we opted for formula feeding. I was around 170lbs before giving birth and through out formula feeding, i went down to 150lbs.

She suddenly ditched her formula after 2 months and started latching full hours and my supply started increasing. She was then exclusively breastfed. I started gaining weight again 😭 recently, we’ve been trying to wean her off by introducing formula once more. She’s 8 months now and she sleeps while breastfeeding and formula in the day. But i’m confused cause my supply keeps increasing along with my weight! I’m almost back to my pre birth weight! I tried eating healthy but nothing seems to work. Not even light exercise!

Any mommies out there lost weight after successfully weaning off?
