“And, it is fair to say, sugar is its own appetite so what I notice is that if you cut the sugar down then you just don’t want to eat as much.

“Plus, there are little incidentals, it sounds silly but it’s suddenly gotten a lot easier to go up the stairs again or lift myself out of the bath because the knees aren’t having to do as much work.”
