For low carb, omit sugar and pineapple. Replace rice with Shirataki/Konjac rice.
To serve recipe in a real coconut, choose unmarked fresh coconuts and shake them to ensure there is liquid inside (the more liquid the fresher they are). In a safe area, use an axe to split the coconut in two - aiming for the center, so you end up with 2 equal sizes pieces. Drain of liquid, gently rinse out (keep coconut meat intact), then fill with coconut shrimp. Place coconut in a smaller bowl on a plate, to stabilize it.
