Your abs don't "pop" since you're so light. The more muscle you carry the more fat you can get away with.
Your cals seem way to low as well. When I was 150 I had to eat over 3500 in Oder to see any progress
I would atleast 3000 ~ BWx20
Try that and go by Murrow not scale
The scale lies lol
Accept if you gain some fat but not too much. Cut back if you are.
Go squat. Then eat a steak. -bruteforce
