@CalamityJane,
Yes, I suppose that's categorically true but, from my reading, I've gotten less interested over the years in dieting as any kind of weighty salvation. In particular, I think continuous off and on weight gain and weight loss is more destructive than being a constant dozen pounds above the published overweight line. I've read pros and cons on that.
Food - cuisines, yes! but also ordinary old food - is one of my greatest pleasures, hope it is for others, know it isn't for some. An a2k poster who doesn't post anymore said he would like it if all his meals could be in some small package. I'm paraphrasing, but he was without the foodie gene. I believed him. For him and others like him, food = function. It reminded me of an old cartoon that stuck in my memory, some guy at a dinner table staring down at his plate with one compacted pellet on it. But, we are all different, which adds interest.
What I've found myself is that what I think is delicious has changed because of my food adventures, especially asian foods, and it's changed towards much healthier fare that I now think tastes as wonderful as I once thought a Lawry's prime rib at the original restaurant did (which shows how old I am.) Now one of those meals would feed me for a week or two, hyperbole, but I'm sure I couldn't make it all the way through the average prime rib dinner of the sixties now (gross).
So, while I frown about diets for those not much 'overweight', I can see changing food interests - keeping the pleasure and eating better as one process.
We have several a2kers who have lost a lot of weight through differing regimes, and while they have a variety of struggles, they are mostly keeping it off. With that kind of weight loss, I can see the benefits of what-kind-of-carb attention, protein, amounts of different fats, salts, vitamins, minerals, and so on. Counting calories in, calories used, has always seemed non specific to me, while I guess it's useful as a generality.
Jjorge et al, sorry for saying you're nuts (pecans? filberts?)
