Kyz - so there is mixed information out there on the amount per sitting protein you can eat. This guidance comes from the study I am involved mainly. Of course, I mention that each individual is different (we’re all unique snowflakes) and how we handle protein per meal is different. The 2nd place I get this info from is my personal experience. If I have 40-50g of protein in one sitting, it knocks down my ketones vs when I keep it under 40. 3rd - amino acids are typically absorbed by the small intestine at a rate of 5-10 grams per hour which puts us at about 30g per meal guidelines. Of course, this also is effected by what else you eat and how your body handles all the food digestion as a whole.
I think I will need to clean up the writing a little to emphasize the individual differences. I think its very important for those starting a keto diet to keep their proteins around 30g per meal and under 90g a day, 20g or less net carbs and each a bunch of fat. Once they’ve adapted, then that is when they can and should start playing with IF, protein/carb/ and fat numbers and see how they respond. The same goes for artificial sweeteners as we all know.
