No wonder the NHS is in a mess.
There is a limited number of doctors nurses and money to fund medicine.
Personally, I'd rather than money and resource to be put towards, say... a child involved in a traffic accident, then some middle aged lazy fit, with every excuse under the sun.
Eat less, move more. You don't need to go to a gym and be running 10k's and benching 240lbs, just go for a walk, walking is great for weight loss, it's free and you don't need any equipment. I love walking usually an hour a day, occasionally go for longer walks on weekends etc it's the ONLY exercise I do, I can't run, I can't lift any weights really, can't do one chin up lol, but it's just about enough imo.
Saying that I'm going for a swim in the sea today, but that'll be one of the few occasions a year.
But your attitude of its harder for me, is just an excuse to justify it to yourself. Guess what buddy, it's hard for most people. Either just get really fat and enjoy that, or do something, but trying to get some drug at the expense of the tax payer is just disgraceful.
