Eric I think maybe your concept of low reward was kind of low in fat. I eat low reward, too, but I eat high fat. How many oxtails can a person eat before you're like ew okay, enough with the oxtails already? For me I can eat one big one and one small one and I can get up from the table. Oxtails are full of lots of fat and gelatin and the meat falls off the bone so there's every reason to find them to be high reward if fat and texture is your criteria, but it just ain't there.
Anyway, dense nutrition works great. High volume (low calorie, low fat) doesn't work as well for me as high fat, low volume. Believe me, I've tried doing high volume as a way to stave off hunger. It doesn't work. I can eat a whole wok full of vegetables.
P.S. my boyfriend just served hot dogs with bacon (Trader Joe's bacon ends and pieces), onions, peppers and vegetables. He really thought I could eat an enormous amount of bacon. It was like oh god that's way more fat than anyone can eat, please no more, please, uncle, uncle!
