How about airfares - as this is really based on weight?
A little while ago, when checking in, I got a roasting over being 0.5kg overweight on the luggage. That combined with my bodyweight was around 65 or so KG.
Guy in front of me was a 'man mountain' probably 150 kg+ So I say to the checkout lady - 'its hardly reasonable being nailed for 0.5 kg of luggage, when the guy in front of me is 2-3 time my weight'? I said it should be combined weight - so if lighter, you get more luggage allowance - I suspect many will not agree with me
We all know if people are unwell and have gained weight because of this, then is understandable - but in the real world the majority of people are obese as they have allowed themselves to be, through being idle, bad eating, lack of exercise etc - this costs the NHS more than any immigrants
As do the legal cigarettes and alcohol.
I think there is fine line to tread, but the fact is if you are a lazy sloth, then you should pay the price as such, and IMO others should not bear that responsibility for increases in their costs/insurance/healthcare and clothing.
Education, food companies, parenting - got to start at the beginning.
What I have struggled to understand in the 'general weight gain' is peoples 'self preservation'. When I have put on a little weight, at some point in time, i've looked in the mirror - or got on the scales, known full well my belly is getting bigger an it's no one else's fault, given myself a kick up the backside, cut down eating bad food, make some effort to do exercise etc. Later on, I fall off & repeat - but the fact I keep myself in check stops me falling too far - I don't understand people who allow themselves to balloon up and just ignore all the obvious health issues.
The amount of people who I see with knee problems and the first issue is they are twice the weight they should be. Strangely enough, if you were half the weight then your knees a would be under less strain - common sense. Not enough of it about....
