I eat 24g twice a day of lactose free whey protein every morning (vanilla flavor). I have gone through many many stages of how to eat it.
First: In tupperware mixer (night before) I mix it with fat free lactose free milk, in the morning it is all appropriately dissolved, pour on cereal, if I have at least 30 mins before swimming.
Second: When swimming first thing, previous night mixture, heat for 1 minute in microwave, and add to 1 mug coffee.
Third: Mixed into my bicycle water bottle with calorie gel for long rides, not the tastiest, but have gotten used to it and only gel is not enough since I am hypoglycemic.
Fourth: After swimming cook oatmeal, THEN add whey powder and mix up, yummy.
Fifth: On Saturdays after 50 mile bike, add two scoops to pancake batter, eat with 2 eggs, and flavored yogurt on pancakes INSTEAD of maple syrup, less sugar. (lemon yogurt especially delish on waffles)
Sixth: Endless variations on smoothies with plain yogurt, usually in the afternoon.
In races, I actually mix the whole 24 in the water bottle with power gel, sometimes though, well, it doesn't go down very well.
