New and have a knee injury!

misti017

I was on MFP for a year and made all my goals. Then I left the site due to some stuff. Well I'm back now because I was training for mud runs and getting ready for my bikini body then blew my knee out 10 days ago. Just got the results of the MRI and have 2 tears. I go to the ortho this thursday, but I need help! What exercise could i do that won't put stress on my injury. And I'm thinking about going low carb since I'm not going to be very active. Any advise would be greatly appreciated! Thanks
