Does protein turn into carbs during ketosis making it impossible to actually get into ketosis? I have seen a lot of articles saying this is the case floating around the internet lately.
Claim: Eating too much protein while doing a ketogenic diet is going to cause the protein to turn into carbohydrates via gluconeogenesis ruining the ketotic state. You should be eating 70% fat or higher 20% protein and typically 10% carbs or less.
Answer: False
Eating protein is not going to have a major impact on insulin or glucose levels while in ketosis. Research has shown that 8% or less of AA’s from protein would be converted into glucose under gluconeogenesis, and insulin would have minimal to no impact.
“Endogenous glucose production (EGP) did not increase after the meal but remained stable for 6 h and then fell. Of the 50 g glucose produced over the 8-h period, 4 g originated from dietary AAs, indicating that under our experimental conditions, dietary protein-derived AAs contributed to only 8% of EGP.”
