You are already in ketosis. It generally takes about a day after you cut your carb intake. What you are not is fat-adapted, and all those things you expect to feel are signs of fat-adaptation. Give it another five to seven weeks before even beginning to worry that you’re “doing it wrong.”
Net or total carbohydrate is up to you. An informal survey showed that about 60% of us here count net; the other 40% of us count total. Either is likely to work for you, unless you are profoundly insulin-resistant.
Weighing 165 pounds at six feet tall is a bit under weight, though not by much at all. You therefore want to be sure to get enough energy to cover your daily expenditure, and the most effective way to do that, in my opinion, is to eat to satiety. This means not eating unless hungry, stopping eating when no longer hungry, and not eating again until hungry again.
In the absence of carbohydrate, protein tends to take care of itself, and the rest should be calories from fat. Three things you appear not to be taking into account are that (1) fat has twice as many calories per gram as protein and carbohydrate (9 cal/g, as opposed to 4 cal/g), (2) meat is only about a quarter protein (in general, you can figure 7 g protein/ounce of meat), and (3) macro percentages are all calculated as percentages of total calories. This means that your ratio of fat to protein could well be higher than you realize.
