yeah you would fall under moderate activity. at your height and weight, you are able to eat 1.5-1.7k cals to maintain your weight bc of ur activity level. anyways, 1.2k is what your body needs to perform its daily functions/what you would need while comatose.
if you want to lean out and make sure you don't lose both muscle and fat, i recommend you keep eating 1k-1.2k daily and aim for 1.5-2 grams of protein per kg in ur body daily (ie 67.5 g - 90 g). lower ur fat and carb intake (i'd say low fat, mod carb, high protein). it's not very fast, but you will fs lean out. u should also aim for at least 2 days of resistance training a week for optimal results. adaptive thermogenesis is a thing, so take a week each month to eat 1.5k-1.7k daily to avoid a plateau.
16:8 fasting is 16 hours fasting (your body begins to burn fat as an energy source at the 11 hour mark), 8 hours eating. i like to sleep thru the majority of it.
also, remember that muscle weighs more than fat. the number on the scale might go up, but u will still slim down.
saying all of this as a MPA native lol i know a thing or two abt this shit.
