Ok, I admit it...I am addicted to fast food, and I eat McDonalds "enough"...(that is all I'll admit to.)
I have found that the healthiest (ok, my definition of "healthy" not too bad on carbs, not overwhelming on fat.) is a McDonalds Cheeseburger, and a medium fry. If you get a double cheeseburger, you double the fat, the carb stays about the same.
The burger is about 30g of carb, and the fries about 45g. Not enough fat to have much effect on my blood sugar hours later. (Fat results may vary with the user, of course!)
The healthiest breakfast BY FAR and I will argue this with anyone, is the Egg McMuffin...30g of carb, minimal fat, bland as heck, but no worse that slapping an egg on a muffin with a slice of cheese at home.
In the USA, McDonalds has a nutritional guide on the back of the paper they use to line the trays. There is sometimes the Nutrition listed on the box or packaging, and if not there is usually an 1-800 number on the box that contacts very quick, friendly, and informed McDonalds folks who can tell you the Nutrition value of anything else you need.
To find out how any particular meal (anywhere, not just Mickey-D's) affects you, the only way to find out is to try it (yum!) take the right amount of insulin (or as close as you can guess) and Test Test Test to find out!
It is a Good Idea to be responsible with the healthy choices, but no point in being a saint, is my humble opinion. Life without cheeseburgers is no life at all. (once again, my opinion).
Hope that helps, good luck.
