Hi Beka,
He weighs about 4.5 lbs (taken the very scientific way of me weighing myself and then weighing myself while holding him). He used to be a bit overweight maybe 2 years ago but lost some weight after a gas/stasis occurence and has maintained since. I don’t think he’s overweight now, my other bun is a bit chubby and just from petting both of them, Peepi is skin and bones compared to Warri. I wonder if he started sitting like that when he was a bit heavier and has just kept it up because he likes the easy access, like bunnymuffin said. 
He went to the vet a couple months ago and got a clean bill of health.
For food, I feed about 8-10 leaves of romaine lettuce, one bushel thingy of parsley, 2 celery stalks, 0.5 to 0.75 cups of bunny basics t pellets, unlimited orchard grass hay, and for treats either half a banana chip or half a baby carrot. And all of that is for both my bunnies, so Peepi eats about half of all that.
