im not a doctor...i guess u shud hav a adequate supply of
protein/carbs/fats for a individual that is injured &works out (if ur still wrkinout) to heal @a appropriate rate. For both injury &wrkout routine.
if u feel that ur takin in too much carbs u can still do cardio to burn off the excess carbs (treadmill, jogging, ect). ur injury shudnt interfere w/ur legs. i dun think it wud, if the appropriate excerise is being implemented.
Speak to ur doctor and
see what s/he has to say.
