If you have 14% body fat and weigh 72kg, you can use the following equation to calculate your lean body mass (body weight if you didn't have any fat):

LBM = body weight - (body weight x body fat %)

With your data, the result is 61.92

So you'd should have at leat 109gr of protein a day.  

 Which is around half a kg of rib eye to get 109gr worth of protein. 

 I'm eating too much already 😆 hopefully I'll get my fat down soon though. Thanks doc 

 Anytime! To be honest, if you're on a carnivore or keto diet, just eat fatty meat until full. There's no need to count calories or grams of anything, your body is perfectly designed to tell you when to stop eating meat.
