Reach gym 5 and do 45 to 60 min workout
Drink protein

What is your goal OP? You can't lose weight and build muscle at the same time, unless you're starting in the gym for the first time ever (which I doubt you are).

Based on what you told us you are very likely undereating.

What are your specific goals?

What is your average weekly bodyweight change over say the last two months?

How many grams of protein are you consuming per day?

What routine are you following and what progress have you made over the past say two months?
