1 cup instant oatmeal 1 medium sized golden delicious apple 7oz serving of plain Greek yogurt
The oatmeal has 22 carbs The apple has 16 carbs The yogurt has 8 carbs 22 + 16 + 8 = 46 total carbs in the meal.
To figure out the percentage of carbs the oatmeal contributes take 22 (the oatmeal) and divide it by 46 (total carbs in the meal) to get 0. 48. (Rounded to keep the math simple) Then do the same thing with the rest of the items so: Oatmeal - 22 / 46 = 0. 48 Apple - 16 / 46 = 0. 35 Yogurt - 8 / 46 = 0. 17
Oatmeal = 0. 48 Apple = 0. 35 Yogurt = 0. 17 0. 48 + 0. 35 + 0. 17 = 1. 00
Oatmeal: GI of 83 Apple: GI of 39 Yogurt: GI of 12
Oatmeal: 0. 48 * 83 = 39. 84 Apple: 0. 35 * 39 = 13. 65 Yogurt: 0. 17 * 12 = 2. 04
(Oatmeal) 39. 84 + (Apple) 13. 65 + (Yogurt) 2. 04 = 55. 53
The oatmeal has 4 grams of dietary fiber The apple has 3 grams of dietary fiber The yogurt has 0 grams of dietary fiber 4 + 3 + 0 = 7 total amount of dietary fiber in the meal.
46 (carbs) - 7 (fiber) = 39 (net carbs)
55. 53 (GI value) * 39 (net carbs) = 2165. 67 2165. 67 / 100 = 21. 66 (rounded)
