I believe jogging is bad - we are not built to move as if we are on a pogo stick. Running is much better, but walking is more practical for most older people.
Pear shape is healthier than apple shape, which means there is fat around your internal organs, but there is not much you can do about your basic body shape, except avoid being very overweight.
We have been told over and over again that diets do not work.....you lose weight for a time then put it all back on again, usually plus a bit more. We all know the way to lose weight and stay at our ideal - eat a little less, move a little more, and don't expect anything to happen very quickly. The weight-loss industry is worth billions and that fact alone would make me sceptical.
As for surgery - well, it very nearly killed my daughter and I have read of many cases where it goes disastrously wrong. It does not address the underlying problem of why the person became obese in the first place. I cannot say it often enough - DON'T.
