Replace weight with smoking, drugs, alcohol, etc.. they are all addictions. It's not as simple as just someone being lazy, though in a lot of cases it is.
From speaking to people I tend to find if it's about somebody else being fat, it's laziness - if it's them, it's a medical or psychological condition.
Humans are bias, I'd want to see data to determine the exact percentage which relate to what - but one thing which is worth noting, psychologists will not speak about laziness, it's an intellectually bankrupt term which doesn't map onto anything in reality.
It's a shame it's used so much, as a short-cut to the complex reality of motivation theory & the host of issues related to problems related to it motivation, ironic that the term 'lazy' is used by people who are too lazy (lack the motivation) to find out it's a void term.
It's not just the lack of exercise. It's the **** diet - English people eat an awful diet compared to so many other parts of the world. Even people who are skinny aren't necessarily healthy.
I'm not skinny by any means but my diet is balanced and fully home cooked from fresh ingredients and I exercise regularly, compare me to the stick insect who lives on red bull and funyuns and who is going to live longer?
I don't think it'll work for two reasons
1. Because slimming classes are for meaty middleaged women and no one ever loses weight as a result of one
2. Because the fat *******s will be too lazy to go, they'll sit at home with their ready meal and pop and get fatter.
Thank you for that useful & insightful contribution.
NHS should pay for my next bike then
Assuming you could lease one/provide bank details in-case it 'goes missing' if it really would cost the NHS less then it should be seriously considered as a worthwhile program.
Regarding the OP.
If they want to run a program to aid obese people to lose weight then run a number of different trails - you don't need to open something up to the UK to get some data to see if it's a worthwhile (economically assuming that's the only motivation - which sadly seems the case for many) scheme, do a few studies & come back with the hard data.
If it stands up to critical scrutiny it should be done, the kind of people who have a problem with obese people getting something for free should be rightly ignored - it's a public health issue.
