One thing I miss is milk. I LOVED milk (especially with cereal...sigh...).
I found this product and it has been a great substitute. The one I drink is the 50 calorie (green carton). It has 50 calories, 5 grams of fat and 1 carb for a 1 cup serving. I use this as a base for my protein drink in the morning.
It's in a milk carton and can be found where the milk and soy milk is. You may have to ask the store to carry the 50 cal version because some stores carry the other two version which are as follows: 80 cal/5g fat/7 carbs and the vanilla flavored: 90 cal/5g fat/9 carbs.
I did drink the 80 cal version when I was weaning myself off milk products earlier this year and it was a good substitute for me then because it was 7 carbs vs. 12 carbs and it feels like you are drinking milk.
I don't care for canned coconut milk. This product is thin, like milk, and keeps my morning carb count low.
