not every diet is for everyone and low carbing is certainl only as unhealthy as the person doing it wants it to be
rather like being on weight watchers and using all your points for cake 
every person needs an eating plan that will suit them and their lifestyle and i find it singularly unhelpful to say that one way of doing this is wrong becuase it didn't suit you personally.
we all know that the best way to maintain a healthy weight is to eat healthy foodstuff in the right amount of potion sizes - smaller regularly. and excersise regularly
the maths is quite simple
food is fuel - you must burn this fuel - if you eat a lot of fuel and dont burn it - you will get fat.
so seeing as you must be completely dense not to absolutley know this equation - why is it that we have a million pound diet industry?
its becuase its not as bloody easy as that - that's why. some people need group support and different strategies to control their eating and eating patterns
this is one way that works for some people. not all people, but i think its just bad manners to say that low carbing is wrong becuase it didn't work for you
just as it would be insane for me to say that low carbing is the only way to weight utopia becuase it worked for me
