You can make shakes & smoothies using protein powder that are far better & healthier than Carnation Instant Breakfast.
There are many types of protein powder. Whey isolate protein powder has the highest protein content. You want the isolate form, not hydrolyzed. Unflavored, unsweetened whey isolate is very low carb. It has a sightly milky flavor & dissolves easily.
Pea protein is another, but it does taste like peas. Good for adding to things like soup. Hemp protein is a vegan source. It has a bit of a nutty flavor & lots of good omega fats. I don’t use soy, but there are soy protein & egg protein powders also. I tried egg & it was nasty,
You can mix protein powder with unsweetened almond milk, add whatever flavoring & sweetener you like for a yummy, filling shake that is low carb. I use unsweetened cocoa powder, cold espresso, banana extract, vanilla (not all together).
Smoothies typically use fruit &/or fruit juice. You can add protein powder to these also. Just put whatever you like in a blender. If you want it thick, throw in some ice cubes.
When I was a kid & didn’t want to eat breakfast, my mother made me raw eggs, wheat germ, milk & flavoring mixed in a blender. I couldn’t taste the egg in it. Was her version of Carnation Instant Breakfast:)
