Calculating my recipe: One quarter cup (US) contains 4 tablespoons (US). So 1/4 cup of chia seeds contains 20 grams of carbs with 16 grams of dietary fiber. 85 grams of raspberries contain 10.1 grams of carbs with 5.5 grams of fiber. I use about two ounces of walnuts, that’s 8 grams of carbs with 4 grams of fiber. The butter has no carbs but 11.5 grams of fat. 1 teaspoon of vanilla extract has 0.5 grams of carbs.
I subtract out carb fiber to dose insulin. Here are the net carbs for this recipe:
Chia seeds 1/4 cup: 4 grams
Raspberries 85 grams: 4.6 grams
Walnuts 2 ounces: 4 grams
Vanilla extract 1 tsp: 0.5 grams
Total = 13.1 grams of carbs
Under my old dosing method, I would also count 50% of protein grams and 10% of fat grams as equivalent carbs, but I now let my Loop variable temp basal pick up this dosing.
My morning insulin to carb ratio is 1:4, so for this recipe I should dose 3.275 units of insulin. I’ve been swagging this at 4 units of insulin so I wasn’t that far off. I’ll use this new calculation so that my Loop system doesn’t have to clean up my slight overdose of insulin.
