Let me sprinkle you with some game. There is something called essential amino acids(EAA). Your body needs them thus the essential. Shit goes right to the tissue, unlike protein you eat which has to be digested.
I could reference you to all the studies that show high protein intake spares LBM during calorie deficits. EAAs allow you to get all that protein to your muscles in a extremely low calorie environment. You must activate your muscles and the need for muscle protein synthesis by lifting weights. And not high reps, go for lower reps. If you don't, you risk losing LBM
At your weight, try 40 grams of EAA split into 2 servings and then get another 100 or so grams of protein from food. EAAs will blunt hunger, so keep that in mind.
If you have trouble hitting your goals, might be low test. Go to the doc and get your T levels checked. And if you take TRT while following what I said you'll probably want to throw all your shirts away just to show off.
Oh, and don't worry about water weight and glycogen. Your muscles will soak that shit up when you reintroduce carbs(especially if you do a workout on the day you set to go hard on carbs), but after the 2nd day just chill and try to eat sensible.
