Its really simple, eat nothing but chicken and/or turkey (high protein, low fat, no carb). You will not become keto adapted or fat adapted.
Alternatively enter into nutritional (dietary) ketosis with a high fat diet, then switch to chicken and/or turkey only (high protein, low fat, no carb) you will not remain in ketosis.
Do you disagree with that? Have you seen any study that shows fat/protein ratios are immaterial to nutritional ketosis?
