No longer rehabbing but I typically try to walk 10,000 steps a day. Sometimes all at once or sometimes broken up into 2-3 walks in the same day.
I also do intermittent fasting which basically means I only eat from noon to 5.
Mostly protein based trying to eliminate fast food, carbs and sugars.
I read quite a bit from Dr Bergs website or videos
