egg whites are alot lighter i find egg yolk really heavy going to eat and it can make me feel like i've eaten alot more than i have.
the reason you don't feel hungry is because you are in effect eating yourself so when the body feels pekish it just stripps off a few grams of fat here and there.
i'm not a big veg fan never have been so i force the leave salad down. usually i melt some creme frachie in a pot and mix in quaterof a teaspoon of mustard and drizzel it over the salad.
To infinity and beyond!
