You can reduce protein later on if you stall. For now, it is more important you keep your carbs under 20 g to get fat-adapted and eat enough protein and fats at your meals that you aren’t hungry in between and before bedtime.
Like Daisy said - some people feel more full and stave off the hunger longer with more protein… some with more fat… Whatever works for you until the hunger tapers off and then you can start looking at protein and fat macros.
FWIW, I have only tracked carbs and never cared what my fat or protein intake was but some people have to track it or they overeat. Not taking the first month - EAT! Don’t get on the “lying liar who lies” (scale) for a while. Get your body adapted into burning ketones for fuel and tweak macros later.
This may not work for someone only trying to lose 20 lbs, but in your case the main goal will be to reduce insulin response so you can unlock your fat stores. This is done by eating low carb, no snacking and reducing the number of times you eat per day and extending the time between meals. You can almost do these in that order - first lower the carbs to < 20g (check), then stop snacking (couple of weeks later) then reduce your eating windows (after fat adaption - 6-8 weeks or longer).
