As so many have already said, in the beginning eat however much you want as long as it’s Keto.
Personally for my first few weeks I didn’t check for any nutrition besides carbs and sugar. I didn’t try to replace the foods I was eliminating and just basicly went Atkins and I are ALOT of it and honestly it was mostly protein to get me thru the transition; 2lb steaks, bacon, eggs, tuna fish, chicken wings, etc…(3000 calories a day easy at first)
Then one day 3 weeks in I decided to start checking all my macros and naturally I was SPOT on with my protein just from listening to my Hunger, low on carbs and I was even lower on fat macro then where I could potentially be for my desired numbers.
Stick to it, it’s seriously worth it. You get to a point where keto food is so much better then the carbage, full disclosure I chose to lightly cheat today on vacation in Asheville for the very first time in 5 months, and honestly I don’t miss anything I sampled today that wasn’t keto and every thing I enoyed and would have again was already keto. Best of luck! KCKO
