Well, I have to disagree with you Jim.
I discovered long ago that there is no one - absolutely no one who is an expert in me and my endocrinologolically challenged - except myself, of course. I now live in a happy zone building a wall to keep out the Expert stuff that doesn’t work for me.
If only I had discovered this earlier, then I wouldn’t be in the physical condition I now am.
All those expert pearls of wisdom that turned out to be corrosive stink bombs... eat less, move more, CICO, all you need is willpower, if I can do it then anyone can, go for the burn...
Nowadays I require a great deal more from an Expert than numerous repetitions of ‘I am an Expert. I am right and you are wrong - so stop arguing and do what I tell you!’
