How many meals a day does Wai advocate anyway? I've seen some wild claims of up to 9 meals a day. I believe it likely that diets that advocate eating many small meals a day do so because they advocate excessive amounts of carby foods like fruit juices, sugary fruits, starches, etc. Some people tend to get hungry pretty quickly after eating carby foods. I think that anything over 3 meals and 1 snack a day is excessive, and less is probably better for people trying to lose or maintain weight.
I agree with Tyler that one can make at least a partial judgment about a diet if one follows it mostly (unless the one or two differences are major). It seems kind of nit-picky to claim that not eating the prescribed # of times means one can't make any judgment.
I really only know from my own experiences. Whatever I read, well, I don't fully know it till I try it.
When I was vegan I had to eat many times per day, or feel like I couldn't be. Switching to pd, I fully cultured cream and butter (with a drop of unheated honey mixed in), drank celery juice and all in all only ate one fruit per day. Of course I ate raw meat and lots of raw eggs. I ate three moderate size meals per day altogether, and never felt like I needed more, but felt satisfied. Actually, I'll go back to the vegan here for a second, after too long on that I still never felt satisfied but I couldn't eat more than like a bite in a day either.
I write this all past tense; because my diet is mixed now. All I ate since this morning is (all raw) 1 two oz fisheggs, 2 three oz bisonshoulder, 3oz unsalted grassfed hardish cheese, 4 four local eggs, 5 one oz cultured unsalted butter, 6 no water, that's it. I'm not really sticking with one diet. I am hoping to see if I can stay away from carbs healthfully. So far so good I guess, but I might change my mind tomorrow as to what to eat. I can't tell you. I've been varying a lot.
