You say I don't care about people who have problems I don't have. You know what? My not having them wasn't an accident. I've put on a bit of weight at some times in my life, usually when I wasn't doing my normal level of physical activity for one reason or another. I enjoy a burger or kebab now and then too. And yet somehow I never wound up obese, because like most adults I know how to eat salad for lunch instead of a burger and I understand that sugary drinks are bad for me.
Let's be clear about this. Being clinically obese isn't just a slight loss of control over your weight, it's a serious condition that develops over an extended period with obvious symptoms. If you really can't control your junk food cravings, you should be seeking proper medical help as soon as possible, because being severely overweight is a condition that can severely harm or even kill you. If you really do have a clinical eating disorder, treatment at work is the least of your worries. But of course there won't be any doubt that you have a genuine medical condition in this case, because obviously you'll be seeing your healthcare providers and undergoing treatment.
With the possibility of genuine medical problems acknowledged, let us be equally clear about reality. Almost everyone who is obese could control their cravings. Most obese people do not have an addiction in the sense of a dependency where cutting down on the junk will cause serious harm or medical complications. They could choose not get that 500 calorie drink from Starbucks on the way to work, not to go to McDonalds for lunch, and not to live off microwave ready meals at home. They could get off a stop or two earlier and walk the last quarter mile to work or the shops. Their problem is not addiction, it is simply a lack of willingness to look after themselves properly if it means giving up something they like or doing something they don't enjoy.
I don't see why anyone else should lose out because of those people, just because they can't find the time or the willpower to cook a decent meal or eat a salad for lunch like the rest of us. You want inhuman and cowardly? That would be the guy who refuses to take the most basic responsibility for their own health and then expects the entire world to adapt to the inevitable consequences.
IMNSHO, by arguing that these people are somehow the victims here, you are the one doing a disservice to the unfortunate few who really do have medical conditions that cause similar symptoms and really do struggle to overcome their unlucky disadvantages.
