Bella's leptin was 10.89 back in 2011. Insulin 79.66, glucose 88 and ACTH 24. All done at Cornell. Fat and blubbery like a walrus, over 200lbs overweight. She was ~20 years old at the time. She's a large pony, most likely a Welsh Cob/Arab cross.
3 years later and massive diet and lifestyle modifications have gotten that 200lbs off her, but she does have those residual fat pads. Any time she's stressed, they puff up again.
Her most recent glucose came back at 70, and I'm waiting on her insulin results.
