I have been thinking about this recently, I am overweight but live a normal life (ie not bed bound and on an oxygen machine).
I tend to be in the cycle of lose it all, gain it back BUT get to a certain weight and start losing again.
Some people obviously don't hit that certain weight and keep gaining, this ruins their chances of a normal healthy life and I can well imagine they get to a point where food is the only thing they look forward to in a day.
Throughout their weight gain journey they will undoubtedly have seen many medical professionals that tell them how simple it is to 'eat less and move more' without taking into account the changes that have already happened to their bodies making the weight far harder to lose and keep off, not to mention the psychology behind it (no one willingly gets to the point they are bed bound by something preventable if they are fully mentally well).
Can you imagine the justifiable uproar if an anorexic sought medical help and was told to 'move less and eat more' before being sent on their way?
I think we will see more and more people becoming seriously overweight and unless we have adequate medical care to prevent them from spiralling into constantly gaining weight it will become an American style issue where we end up removing windows to get them out of their houses and into bariatric ambulances.
Just wondered what other people thought about this issue.
