By the way, my theory is that it is not really obesity or high BMI that does us in. It's the lack of physical exercise, the driving everywhere instead of walking, the couch potato lifestyle that shortens our lives.
A neighbor of mine is a short and slightly heavy woman, also in her 50s. However, it is just her built and I will readily concede that she has more physical exercise than I have, is more fit in the cardiovascular sense, can outrun me, and outwork me in physical labor. But generally speaking, if one has to walk a few miles to catch a bus, or walk those stairs through the London Underground, plus as expensive as their food is, one has no choice but to have a low BMI and be fairly fit. It's by necessity more than personal resolute, I firmly believe.
I've been living in the UK for 5 weeks now, feeding ourselves, no car, hills everywhere, lots of hikes as well as having to walk everywhere and I'm putting on weight
While food, I'm sure, is more expensive than in the USA it is not overly so. Quality cheeses and "artisan" breads that we love and eat in USA are actually much cheaper here. e.g. a large whole grain extremely tasty fresh baked, still warm loaf from our local supermarkets costs £1 ($1.60) and we pay well over $3 for that in the USA.
We usually put down our incresed weight when we visit here to eating out, drinking beer and using a car. But we are having difficulty controlling our weight even when fully in control. It is quite frustrating, but still have a few more months to change things.
btw, my brother and 2 sisters are obese, as are DW's younger sister and brother. Both our mothers were obese, and my parents never had a car so being forced to walk and catch the bus certainly didn't help.
The local gym we attend here has a time every day where the NHS sponsored obese members come to work out on the treadmills and bikes etc. I've seen this before with one of my sisters and also with her neighbor where NHS prevention programs worked well. With my sister it was was to quit smoking, about 7 years ago. To ensure she was sticking to the program she had to go in each week and have a CO test to be sure she wasn't cheating, and they provided the nicotine patches she needed to kick the habit.
I commented on how much weight her long time neigbor had lost and how great she looked. Sis told me that the NHS paid her Weight Watcher fees as long as she continued to lose weight. She lost a LOT of weight, and kept it off for 12 months and was provided a free tummy tuck paid for by the NHS.
Not saying that prevention programs are the answer to lower long term costs but it must help. Many companies in the USA have fitness programs and incentives to keep their health costs down, and I assume they continue to do so because they believe it works somewhat. (could just be a gimmick of course).
