I had to lose weight and exercise or go on blood pressure lowering tablets. I've seen what long term use of BP tablets has done to my pa (along with the other 8 tablets he takes a day) so I chose the former but don't like fad diets and I'm not one for exercising for the sake of it.
Diet wise, I cut out most but not all carbs. No white rice, fewer spuds, no white pasta, no white bread and less bread in general. Much less beer, more wine! But I still need calories so I upped the protein and fats a bit and I uppded the veggies a lot. Nothing extreme and I haven't had any issue changing my lifestyle accordingly. I don't call it a diet, it is now the way I eat. I still go for the occasional curry with a naan and the odd pizza but my day to day diet has changed.
In terms of exercise, initially I did go on the bike and to the gym because I was unfit and my BP was very high. However now I have bought a dog and walk a lot. I still go to the gym but that's because I can go during my lunch hour at work so doesn't cut into my workshop time
I lost 6kg in a few months, I wasn't massively overweight, down from 81 to 75kg and my BP is about normal unless I have a few beers/wines.
I had high cholestrol before and that has gone down a little but I am not worried about that, Statins as a preventative measure for heart disease is a big con in my researched opinion and "high" cholestrol is no indicator of being unhealthy, all this cholestrol blocking arteries is also largely a big con in my researched opinion. Total mortality of people on statins for preventative reasons and people not is just about the same, you just die of something else!
