P1) If a higher proportion of amino acids are spent on gluconeogenesis while on ketogenic diets compared to non-ketogenic diets, then a lower proportion of amino acids are available for hypertrophy on ketogenic diets compared to non-ketogenic diets.
(P→Q)
P2) A higher proportion of amino acids are spent on gluconeogenesis while on ketogenic diets compared to non-ketogenic diets.
(P)
P3) If a lower proportion of amino acids are available for hypertrophy on ketogenic diets compared to non-ketogenic diets, then ketogenic diets are likely to cost anabolic potential compared to non-ketogenic diets.
(Q→R)
C) Therefore, ketogenic diets are likely to cost anabolic potential compared to non-ketogenic diets.
