Post Op Diet Question

From my research on this site, I've learned about the post of diet. My question is: when we've dieted pre-surgery, our body thinks it is in starvation mode and hangs onto everything it can to protect itself...why doesn't it do that post-surgery?

ok i am not totally 100% about this ...but your body does do this ..It is just that you are putting sooooo little in there that it has to take what you have stored up . Also you have to becare cause you can end up loseing muscle and not fat after your surgery ...that is why they want you to work out as much as possiable post-op. Cause if you are burning muscle then you can not be burning muscle ...This is what they told me anyways ..... Laura

that makes sense....thanks!
