So I've been running for two years now and the past 3-4 months I've been unable to afford protein shakes, I've never had a great diet but prior to being unable to afford protein shakes I never had any lasting injuries but now that I've stopped taking protein I've gone from one shin splint to another and now I am getting bad ankle pain. It feels as if I am falling apart and after reading how important protein is I've found my culprit. (It isn't because I've changed my training, I am running the least amount of mileage per week in a long time)
I know that protein powders aren't as beneficial as a healthy meal (don't bore me with the details this isn't what I am here for) What I am asking is how long should it take for protein to repair my injury once I get protein into my diet again?
I've already started, I had one shake last night and I've had one this morning, I am aiming to have two a day. Is two a day enough for an injury to heal for someone that has a low protein in-take when it comes to solid foods?
