Welcome. I too when starting wanted to not fumble. I did and still do. Even so I made progress and I would hazard a strong educated guess that the mistakes actually helped more than hurt because as I refined and tweaked according to my needs, I kept “switching it up” which solved some issues and created new challenges as I continue to learn about how my body reacts.
Overall I tracked everything and still do. I am an engineer and find that to be synchronous to my nature. Basically it was this: Eat a lot the first three months. Let the body heal. Eat 20 G total of carbs, at least twice as many fat g as protein. If your sedentary try to keep the protein to .7 per LBM. Test BHB and BG. watch for patterns. Use a tape measure and a shirt that fits tight now. in three months it should be far loosser. The keto WOL uses fat and builds LBM. That shirt will prove your NSV.
After 3-4 months things change. You might limit calories or fast in order to break a stall. You might increase or decrease fat. As said elsewhere, because none of us enter exactly at the same place it is impossible to know what you will need to do later.
Again welcome. Hope you stay long enough for your transformation.
