New guidelines have been created, or new advise to be dispensed.
Of course, if a doctor disagrees, and provides his best experience, and does not follow the guidelines, then he is negligent.... and we all know where that leads.... Statins anyone.
The ideal diet is one that we can stay on and lose weight or maintain weight on, and all those other bloody markers. That is physically stay on the diet, psychologically stay on the diet, philosophical stay on the diet, socially stay on the diet, environmentally stay on the diet, economically stay on the diet, ..... and all those other things, not just food. It is the continual advice to try this or that, Paleo, primal, Atkins, Dunkin, Mediterranean, Low-carb Paleo, 19th Century Peasant, Real Food Plan, PHD, Mediterranean, or whatever. No processed foods, sugars, flours, seed oils. No hyperpalatable... Yada, yada, yada.
And everybody has a opinion today, and another tomorrow. Yet only the scales knows for sure, and it does not known anything, for it is a scales.
I know I am not in control of my weight, but some days, I do have control of what is available to eat, and some days not. Such is life.
But what do I know? Breath, smile, and enjoy the circus that life is. Dao.
