Thanks for the link to the editorial press release VDOT. Full of facts it's not, it's an editorial Your further link to the Guardian, is based on the same editorial press release - convenient.
All studies are targeted at a specific point, and few if none are open (i.e. have no point to prove or axe to grind) or altruistic - they need to be funded which means they will be paid for by someone with a point of view to prove. I know at least one researcher whose 2 year project was never published because the facts could not be skewed to suit the sponsors point.
How do you know this information is correct, after all by your own admission you believed what 'they' told you before about low fat and carbs. Will you not appear stupid at some future date when this line of thought is perceived as flawed?
Maybe you should start your own thread, instead of highjacking others (load of smileys and stuff)
The problem with keeping things simple is that really they aren't. If, as you posit the only way to lose weight is to eat less, why bother changing your diet? A little over-simplified maybe?
For every publicised study, there are a hundred less hyped, less headline worthy studies that cover the same ground but from a different bias point/sponsor. and produce very different results. Unfortunately, these studies is they don't fit a good sound bite, or are simply too complex for the layperson to comprehend.
If you're looking for the traditional diet, shouldn't you be persistence hunting animals with your social group, instead of hanging around on 't interwebs
Perhaps this thread also informs on your 80/20 failure thread. If you were calorie restricting, then as asitis suggests your body *may* be holding onto your reserves, and lowering your metabolism, and available energy. Quick google of 'starvation mode' should give you some pointers
While calorie deficit is the *only* way to lose weight, how your body, and indeed brain react to this loss is also worth considering. I think VDOT is presenting a simplified version of Maffetone/Noakes, but without other considerations.
Try more higher intensity stuff to shift the remaining weight, but be careful to fuel for the muscle repair.
