Sigh...I basically want to sound off on this physician but I won't, as it's not his fault for being cautious. Anyway, to game the system I'd go ketogenic (low protein and high fat) between now and your next test. Here are just 2 quick reasons why:
-Less cooked meat intake and way less protein overall (since carbohydrate increase would result in a concomitant protein increase, although not higher than previous levels, it would be the opposite way of where you're trying to go)
-decreased water retention= moderately lowered blood pressure ( depending on your individual physiology) which will make your doc happy
I'd be thinking ~100-120g of protein and 200-250g of fat depending on how big you are with <50g of carbs/day. Grassfed beef and bison would be good, especially with the fat.
