You are right Bleemster, it is what a lot of us find out about DAFNE, might look good on paper and it is good to have a guide , but you really need to test a lot to see how you react to foods.
I mean they tell you that your Basal will cover you for a pure protein meal of say bacon and egg, not to Bolus for it, but I need 4 units for said meal...More than I do for my fruit breakfast, again trial and testing! Protein will break down to around 60% Glucose, so if you do not produce insulin you will need to Bolus for it...they say you must include carbs with each meal, I do fine without them
Well, you know that the foods you love and what you deem as "normal" are doing you no good at all, so you can either carry on upping the meds and eating them or change, the NHS don't seem to care either way. But you will further along the line as complications set in, hopefully you can sort things out before this happens.
IMO, there is no more over processed food than boxed cereals, (Grain, over processed Eekk!)
A Dietician said to me years ago that Nutrition wise you may as well eat the box for the good it does you. You can buy Mixed berries in a bag frozen from Farmfoods for 99p, it's pretty decent. Tesco do the sliced frozen strawberries and blueberries for £2, and whole frozen strawberries for the same. I mix them in with the Farmfoods ones to keep costs down. You could have them with Greek Yoghurt, or cream, warm or cold. Does not work out too expensive, if you aren't spending it on a load of processed food aswell.
Almond flour pancakes are another good one for breakfast, there are a couple of Recipes in the low carb section. Also Bacon and Egg if you have the time. i do melted cheese in baby Gem lettuce with chopped peppers for lunch...Teas can be cheap if you batch cook the cheaper cuts of meat and have them with lots of veg, frozen and fresh to keeps costs down again...The combinations of food choices are endless. Just eat whole foods cooked from scratch so you know what goes in them...Lot's of veg. You will lose weight, which will help with insulin sensitivity.
As I said look in the low carb section on here, research low carb on line ,there are loads of ideas out there..Good luck with it all.
