My situation is this: I am two and a half weeks post op. I am back to doing crossfit for my work outs 3 days a week and walking twice a day for thirty mins. Within a day I am getting in 15-20 grams of protein, no more than 400 calories and 64 oz of water. My question is this: Am I being counterproductive in my workouts because of my lack of protein? I am afraid that the weight I am loosing is muscle mass along with all this fat. I know that I need to increase my protein intake, and I am working on that. But can anyone guide me to some information on how to know you are getting enough nutrition to sustain a workout routine. Or if anyone would like to provide some of their insight I would greatly appreciate it.

So the bigger question is whether you are trying to do too much too soon. Has your doctor cleared you for this kind of workout schedule? On your question specifically, I'm no doctor but you are going to lose muscle mass for a time period anyway because you can't consume the protein you need. Eventually you will become depleted and your body chemistry will force you to stop anyway. My personal feeling is that if the doctor says its ok, go ahead. Just keep in mind what is happening with your body and stop sooner than too late.

I spoke to my doctor at length before I did this. Two months pre op I had started to do crossfit, so it helped with my recovery. I am not working out at the intensity that I was before, mostly because I don't have the energy. My surgeon has blessed off on everything as long as I can keep up with staying properly hydrated. My main goal in doing this is to ensure I am toned up as I start to drop this weight. I am just concerned that my lack of protein intake is counter productive.
