Technically that article and the science behind it seems to be saying that calorie restriction is a bad idea and strengthening the argument for low carbing (just skimmed the mail argument but have read lots on this study).
When you restrict calories, even if it's not hugely - you create a calorie deficit that makes your body think there isn't enough food around. Your body gradually rewrites itself the more you lose into being more hungry and more obsessed with food - reasoning that when supplies are plentiful again you'll need to build up fat reserves for the next period of famine.
Low carb isn't about calorie restriction. Technically on low carb you should lose even at maintenance level calories because you'll have changed the type of fuel your body burns. So your body doesn't assume it's starving and shouldn't trigger you to overeat in the way it might after giving up a low calorie diet. At 'the very least the effect shouldn't be -as bad- if you lose weight low carbing.
I suspect the problem is most of us did low calorie first.
Still I don't really like the suggestion that dieters are 'doomed' to regain or that we can't help ourselves when it comes to giving in to cravings. It makes it harder and it can feel like the odds are against us but people can and do lose weight and keep it off. We can all do it, it would just be nice if people appreciated what a fight it is instead of saying it's laziness, greediness or just a case of eating less/ moving more.
Being overweight, I feel more and more, is not an issue of how intelligent, how disciplined, how good we are as human beings - though that seems to be how the world judges us. It's a question of luck.
For me, I was a thin child, got my period and have been obese ever since. I found out in my 20s after going through a premature menopause that I had severe hormone imbalances which - as well as ultimately causing me to gave osteoporosis and a raft of other serious health conditions aged 30 - was a primary factor in my weight gain.
But by then I'd been conditioned by miserable years of bullying to believe I was stupid, lazy, worthless, a bad human being, because of my size.
I can't shake that. I can know better than to judge anyone else on the same principles but I can't not judge myself. And I contributed. I learned to comfort eat. I wanted crisps and chocolate because all my other friends were allowed them and the fact I wasn't felt like a punishment when I couldn't understand what I'd done wrong. Eating 'bad food' became a way of telling myself I was okay and a way of punishing myself at the same time.
It's a complex business, this weight thing. I don't believe it's ever quite as simple as 'eat less, move more'.
