““Dose response studies indicate a linear increase in skeletal muscle protein synthesis with ingestion of high quality protein up to about 20-25 grams per meal[127]. With protein intakes twice this amount, there is a marked increase in protein oxidation with no further increase in protein synthesis. When looked at over the course of a day, there is no credible evidence that protein intakes above 2.5 g/kg body weight lead to greater nitrogen balance or accumulation of lean tissue. Another reason to avoid eating too much protein is that it has a modest insulin stimulating effect that reduces ketone production. While this effect is much less gram-for-gram than carbohydrates, higher protein intakes reduce one’s keto-adaptation and thus the metabolic benefits of the diet.””
