My body definitely has a set weight that it wants to maintain. If I consciously diet I can lose 2-3 kg pretty easily (in 4-5 weeks) but going below that takes a real significant effort and if I return to eating 'normally' then I put the weight back on over a few months.
But, on the other hand, even if I consciously try to eat more for months on end (to put on weight), I only end up 2-3 kg heavier than my 'set weight' . And when I stop over eating....I lose the weight (even though the overeating is supposed to be to increase muscle!)
If I just eat 'normally', neither trying to gain or lose weight, I stay pretty much within a kg either side of my 'normal' weight.
I'm sure its feasible to re-set your body weight but I dont know how much effort is involved because I've never managed to do it.
The major drop in metabolism in that NY Times article is a reason why the 5:2 diet seems to work so well - you cut calories but no metabolism change.

Most people don't experience this kind of withdrawal because they never make it past the first three days of restricted carbs. The sugar withdrawals are too powerful. It's difficult when you first wean yourself off of carbs and get most of them from veggies. There are huge benefits to it once you learn to sustain that type of eating though.
Dont confuse the impact on your body of carb withdrawals as showing that carbs are 'bad'. Your body has to adjust from using its preferred/easiest means of energy and, until it does, it doesnt know what to do and you feel bad and your body will seek out what it knows and likes.
But that doesnt mean its going from a 'bad' situation to a 'good' situation - its going from feeding your body with one form of energy to not giving it that form of energy at all. There
might be a benefit in reducing carbs, in particular simple carbs, depending on your actual diet. But that is an individual issue, not a general proposition.
eg: for me (just me): cutting out unnecessary carbs, like dessert, doesnt change my weight on its own - I have to cut out more than just dessert - so I may as well have dessert!
(that said, for sure low carbs will reduce weight, if that is what you are aiming for. And whether there is an impact outside of weight - who knows).
