huskies4ever basically nailed it.
Underrating won't do you any good. You'll probably only lose muscle underreating. You can (and probably should be) eating at least 1500 healthy calories every day (possibly more depending on your TDEE) as well as a good amount of protein (and possibly less carbs). But you can't just eat right to fat sear, you need to be working out to balance out the calories you are consuming and gain muscle. that means you need to do proper amounts of cardio and resistance training--preferably weight-lifting. if you can keep up a healthy diet (oats, chicken breast, almonds, vegetables, etc.) and keep exercising you're gonna make it. Just remember that fat loss and muscle development is a slow process.
We're all gonna make it brah.
