I recently injured my knee and was restricted to just weight lifting. After about a month, I was allowed to incorporate cardio back into my routine. I am trying to lose weight. Due to just lifting weights my body demanded more food. Once i incorporated cardio, the number began to come down. My BMR is 1700. However, the amount of food my body is requiring (even on days i don't work out) is 1900. I was told that i need to do the same amount of cardio i was doing before i got injured. I did and that's were it came to 1900. I did a little more but it still stayed at 1900. How do i get it down to 1700?
