When I was on Pritikin, my normal meals were breakfast of some type of hot cereal (oats, malto-meal, etc.), lunch of pasta, dinner of brown rice and beans. Snacks were rice cakes.
Recently, I saw someone do an analysis of how much rice and beans you’d have to eat to get the complete protein in a small amount (3 ounces?) of beef, and it was stunningly large.
I saw someone with a post on Twitter trying to compare eating oats with bacon, in the context of using CGMs. The idea what that “oats”, even though they caused “physiological normal” blood sugar response, were “good”, while bacon (no blood sugar response) was “bad”.
But I can tell you with 100% certainty that I would be STARVING ten minutes after eating oats, and not be hungry for hours after eating bacon. (I ate oats plain. But maybe if I heaped butter and cream on them, I wouldn’t be hungry. But then why eat the oats? Just have a bullet proof coffee.)
Looking back, I’m surprised I made it as long as I did on Pritikin. I was way under eating protein.
Edit: I wish I knew where I saw that info. Unfortunately, searching “rice beans beef comparison” brings up tons of vegan/vegetarian websites where the main argument is based on grams of protein on labels, which Peter Ballerstedt has indicated is misleading.
