@J_A-M has some excellent beginners tips
It can take several days just to get to ketosis esp if you are coming from high carbs. The things needed to get to ketosis are, low carb intake(check) reducing blood glucose(probably check) reducing liver glycogen(can take a day or two at first) and low insulin which can be tricky esp if you are T2D or have IR.
Eating too much protein is possible, eat as much fat as you can at first which is often not enough for most people. It takes a little adjustment to get all the fat in the first few days.
Eat to protein to your macro level and if you are still hungry finish off with fat.
I recommend everyone eat to there maintain macros for the first few weeks, your body once ketogenisis starts will need extra energy and its best to not restrict calories. Get it through your head right now that is not the right way to do this WOE eating to satiety or full is really best at first. Calorie restriction will lower BMR and shut down a lot of the functions you really want to be moving at full speed, its a good way to feel like crap, be cold, and get sick.
Weight loss may not happen right of way, take pictures, take measurements, things will start to change, but also healing is happening and that can take some time as well.
It typically takes about 2 weeks for most people to be come keto adapted were they are making enough ketones that your body has spare. Add another 5-7 weeks for fat adaption were you start using the fat directly at most cells and the liver does not have to do all the work anymore.
Keep Calm and keto on
