Hey jet..I hope you'll get past this soon. I know you can
I peeked at your diet; and assuming it's updated fully, then yes, I agree you're eating too little. I know it seems counterintuitive, but it's true
You'd probably see great results if you up your calories to about 1800 a day. That will stoke your metabolism. Just try to make those calories beneficial, of course - Greek yogurts, peanut butter, etc.
Keep at it, you're doing great!
