But here's what a doctor likely won't tell you so I'll tell you what works well for me diet-wise.
Cut the added sugar, processed foods and fast foods. Eat natural stuff all the time (and as much as you want)...fish, meat, yogurt (the whole milk kind with cream on top), nuts, berries, green vegetables, olive oil (instead of other condiments), etc. Drink tons of water. If alcohol, stick to red wine or bourbon. Drink as much water as you comfortably can and shoot for four (16oz) bottles a day. All the black coffee you want to drink (you will learn to appreciate coffee more without the cream and sugar).
After the first week or two, you will feel better and eventually you will actually desire the aforementioned foods and not even crave the other stuff.
Today I had two eggs for breakfast with a 4% milkfat yogurt with blueberries swirled in. Tin of sardine and handful of raw almonds for lunch. Tonight, I'll likely have a steak with asparagus and a garden salad with raw sunflower seeds, more raw almonds and olive oil.
It will be about 1900 calories when all is said and done and I'll not have been hungry all day. I'll finish the day with a couple glasses red wine.
Some call it keto, some call it low-carb. I just call it healthy eating.
All Type 2 diabetes is out of my system and my blood work is fantastic.
Doctors won't tell you about the above however. Like global warming fanatics, they will keep preaching that long discredited "low-fat" balanced diet and tell you to do nutty stuff like remove skin from chicken, subsitute butter for margarine and to eat egg whites. Don't listen to them...on that part.
