This can work incredibly well if correct conditions are met but also are far more likely to go wrong as the efficiency of the diet changes massively if the principle it is based upon is not accommodated correctly.
Well, I dunno what she wasn't accomodating - Her doctors recommended the fad one, based on 30 years of success (does that mean it's not a fad any more?), along with other people she knew who'd found it worked.
(or over a sample of bigger people

)
So it's you who's said if someone claims they're fat because of a medical problem it means that they're lying (unless they're female or male but have ovaries).
No, I said the vast majority of males who claim it are lying, since women tend to have more susceptibility to conditions and medications that contribute toward making them fat.
It hasn't been the default response in this thread.
The general response has basically been that it's '100% to do with eating too much and being lazy, nothing else'.
It does seem almost certain that only a tiny percentage of people who are fat are fat due to medical problems, but you're the only person I've seen talk about lying so bluntly.
I've had discussions like this at length before and with numerous medical professionals.
maybe they're skinnyfat and you live in a chavvy area? (note I said 'fit and active people' that doesn't imply all skinny people) Regular exercise tends to reduce stress btw..
I actually live in a pricey area (got a good deal on the rent) where rich people get fat on rich food... which is probably why they're so happy.
Skinny rather than fat - This is GD, after all. But as far as regular exercise goes, in our office it is indeed those who go to our gym or out running at lunchtimes and so on that are always so stressy. Do they need to run more, you think?
maybe your own personal bias and perception is way off tangent...
Maybe the reason fat people are more miserable is simply because the skinnies are always having a go at them?
BigDannyO has already demonstrated that you're way off base with your 500 calories argument above
We discussed the theory. The reality doesn't match up and far more qualified people than me still couldn't sort it, so that's that one...
