Welcome back Cofty ! thanks for the recommend, I have ordered Taubes' book, which may spur me to do some "weight watching" again.
I did the same as you, worked out a sensible system of losing weight, without silly cutting out of any foods, combined with exercise, and lost 3 and half stone, by December 2019, then, what with bloody lock-downs etc. I have put over a stone back on !
I need to lose weight, and get fit, sadly my great pleasure of walking in the Countryside is denied me, because of personal circumstances. (No, I am NOT in Prison......... yet!)
