Someone I know has just lost 6 stone in weight! He said it was just giving up bread and keeping off obvious foods that are bad for you and eating sensibly. He had severe back problems and was in great pain and was supposed to have an operation on his back - this was why he lost weight, but now the back pain is minimal and controlled with drugs and he has now been told that he probably would not need an operation now because of his weight loss. He is a type 2 diabetic.
I have lost half a stone during lock-down. I eat lots of nice things but use sweetners instead of sugar, never have take-aways - except perhaps bought fish and chips about once every six weeks and have lots of home made smoothies ie I have just had one today - ie blend two tangerines plus a ripe banana, a dessertspoolful of low fat creme fraiche plus a little milk to make it up to a glass full. Delicious and very good for you. Obviously, one needs to be careful with bananas as very ripe ones contain a certain amount of sugar, but you can just use half of one if worried on this score. I make homemade stews in my pressure cooker and freeze them down in individual portions but I use some root vegetables - something people on low carbohydrate diets might not want to do - my bloods are, fortunately, always under control. My very best wishes to everyone wanting to lose weight.
