just started and im feeling SUPER excited (18 yr old)

HI GUYS!!

I started at 85kg 5'4 and I've just started 4 days ago! I'm wondering how fast would it work on someone like my age since I am only 18 and havent seen anyone young on their journey! I've been in a calorie deficit and go on walks regularly Hopefully since I'm younger my metabolism is also faster to get rid of my fat!! Just curious for everyone's input
