"crap"...the never ending merry go round of what is or isn't good for us,what we should or should not eat...no one has a definite answer.
I was into weights,running etc when I was younger and I've always tried to moderate what I eat
After my hip replacement I resumed a recommended fitness routine to strengthen the muscles and get some mobility back. It worked but after about three years recurring sacrolitis has stopped me. The doctors will give me pills I don't want so I just put up with it.
I work in a factory where I'm occasionally on my feet but can have days seated or more relaxed. Surprisingly we measured our steps with one of those bands once during a machine set up and it amounted to three miles including lots of lifting, carrying and bending .
