Hello TIRED OLD GAL, and welcome to the Forum
I was diagnosed with D just over 20 years ago; as well as medication for that I was prescribed Atorvastatin
It was OK for several years but then I developed the aches & pains of Statin side effects
I saw my GP; my cholesterol level was just under 5 and agreed that I could come off statins, and try to control things by diet and exercise
I was already on a diabetic diet, reducing carb intake, and applied that more rigorously
For a while I had been reducing the amount of meat that I ate, and similarly I worked on that even more
I stopped eating any kind of processed or cheaper meat. even if they were grilled or had the fat fried off; so mo more burgers, mince, sausages, bacon; also joints or chops with fat. Now and again I'll have a lean steak
Don't be afraid of fat! Opinion has changed, and now you can have fat & oil as long as it's the good stuff like olive oil & oily fish
I used to use sunflower oil or anonymous 'vegetable oil' but now I only use olive oil. I don't do much frying now anyway, so just a small amount for that, plus dressings and in recipes. It doesn't need to be the expensive extra virgin, cold pressed etc. stuff, just cheaper to medium priced is OK
I make vegetable stews from the usual stew veg and beans & lentils. I've never had much success cooking dried beans, but search supermarket shelves, Asian shops & similar and there are a lot of beans & lentils ready to use - canned, in cartons, which look like smaller versions of the cartons of orange juice, and plastic pouches - Merchant Gourmet and other brands. You can also put a can of cheap baked beans into a stew; they are simply haricot beans in a tomato sauce
The only dried lentils I use are the small red ones or soup mix. Yes, there is some carb in the barley, but we're only talking about using a small amount, not huge shovelfuls every day
I've been eating more fish
You can use fresh fish, otherwise have a root round Iceland's freezers. Avoid fish in batter or sauces, but you can find plain fish ready gutted or filleted
Also canned or vac packed. I don't like the tomato sauce, so I get them in brine or oil
These changes in my diet didn't happen overnight. I took a few months to gradually change from meat to veg & fish
Oh, and not forgetting an increase in the amount of salad I was eating; I like chick peas salad
Remember, nothing in the body happens in isolation. You may well find that when you make these changes, including more exercise, several things improve at the same time - weight, sugar control, cholesterol, blood pressure, plus generally feeling more lively
