Hi, @loaks I too welcome you to Connect. I have type 2 diabetes, diet controlled. @dorisena has some great advice there, she deals with this more than I do, my diabetes seems to be pretty mild. It really improved with a weight loss, which is pretty typical. Did you find that helped with you?
As dorisena commented, exercise is important too and I try hard to get a good amount in daily which has been harder now that we are self-isolating, but there are many excellent exercise videos on Youtube. If you are over 50 there are really good ones by
Jenny McClendon - https://www.youtube.com/results?search_query=jenny+mcclendon+exercise and also
Schellea Fowler https://www.youtube.com/channel/UCiWPU83VmOXjQ6xY0gIrhIQ plus if you are on Facebook there are exercises by Silver Sneakers.
I generally alternate my breakfasts between plain yogurt with granola and berries added to it - there are some low carb granolas out there but you do need to check the nutrition info which I always do. The other breakfasts I have are oatmeal, with some chopped walnuts and berries added to it, and a couple of times a week I have an egg with cheese and a low-carb English muffin. Fiberone makes some decent ones. There is another brand also but they get very hard in the toaster.
I almost always have a salad for lunch and for dinner meat or fish and vegetables or salad.
I do manage to squeeze in some treats like dark chocolate but I try to keep most of the treats low carb.
Fruit is great but it does tend to be high in carbs so you do need to keep an eye on the amount of it that you eat.
I hope some of this will be helpful to you. Please feel free always to ask questions.
