We both had medical screenings in January and were told our cholesterol was well over normal although our weight was only a bit above normal. I think it was Christmas after effects really.
We looked at our diet and decided to buy no more chocolate, biscuit or cakes. Also we cut out foods with high fat content, especially saturated fat. Helped by the lockdown we walked a lot and couldn't go for a coffee and pastry.
We both lost a stone in 4 months. It seemed like hardly trying at the time. We were still eating 3 meals a day and desserts. We started to eat more as you can't keep losing weight but it didn't seem to stop us losing weight. Now we can go in coffee shops and have bought a few cakes and have stabilised. Just recently I've added an extra nights alcohol which seems to have tilted the balance, that's a Tier 3 effect I think.
We don't eat much meat, hardly any all.
I've always done some jogging and some weights. I think what you eat makes more difference than what you do. Both exercise and maintaining food regime is hard work. As soon as you lapse you've lost it so it needs to be what you enjoy. You might think it better not to try to hard as you need to enjoy yourself.
