I have been lurking around these boards for a little while now, so I thought I'd introduce myself.
Let's see: So, I have been a vegan for approximately 1.5 years, and a vegetarian for several years before that. I found the Dr. McDougall website in an attempt to eat more healthily. I would say I eat a moderately healthy, though high-fat vegan diet---mainly because I consumed large amounts of tofu, nuts, and other high fat vegan foods. I also cook using lots of oil. Honestly, it's never occured to me that this wasn't healthy.
I don't have a weight problem. I am thin, in fact. However, eating high fat leaves me feeling like crap a lot of the time, so I decided to give this a shot, but I wouldn't say I am following a strict eating plan by any stretch of the imagination.
I love to bake, however, and have stoppped using oil. I have stopped sauteeing in oil, and have generally tried to avoid oil, period. I have also cut down on high-fat vegan foods, and have stopped eating altogether the deep fried crap to which I have become accustomed. I ate a lot of whole foods before, so I am not changing so much what I eat as much as how I prepare it. I have been surprised by this foray into no-oil cooking; the results are surprisingly good, and I feel a lot better.
I have been doing this about a month now, with some immediate and obvious results. My skin is much, much less oily, and generally I feel much better. I probably eat too much sugar/flour to get the full benefits, but I have still noticed improvements.
I am a male, in my early 30's, and that's about it. I am sort of doing this whole McDougall thing "in the closet"---that is to say, I haven't really discussed this at all with anyone, and have just made changes without anyone noticing; mainly, I don't want my family and friends to think I am 1. trying to lose weight or 2. become a "health nut." I would definitely not describe myself that way; besides, it's not "nutty" to like feeling good.
Sorry for the exhaustive intro...
