Borat.
You seem lost.
To help define some terms and drive you out of this murk, think of Veganism as more religious; the code for which is up for interpretation by your particular bent, and for the individual to assign personal meaning. It pertains to every aspect of everyday life, and is followed by all sorts of people from those humble like monks to those radical like evangelical. It is quite involved.
Vegetarianism on the other hand is far simpler. It is little in the way of a belief system, other than minor conscience (what some may simply call an omnivore guilt complex) and by comparison would be thought of better as purely a simple ethical dietary choice, that pertains to eating first contact animal products (something such as flesh which is normally obtained only through the slaughter of an animal). It sounds like you truly mean the latter.
I'll admit that issue of "morality" has been on mind as a reason as to why I'm contemplating a vegan diet, but I don't plan on taking it to the extremes of the people you mentioned. I just want advantage of the organic side of the diet, which might help not off some fat.
Living by the strict confines of a Vegan lifestyle does not correlate directly into a diet consisting of organic food. In fact, unless you're particularly hardcore you're
more likely to consume overly processed food on a Vegan diet. What you're after, by the sound of it if you want organic food, is something more along the lines of a Paleo diet. If you have morality issues, then Vegetarian Paleo. Good luck with that one.
It can be done, but at that point it's worth looking at your motivation, as best as they can be made out from their vague existence (as portrayed by yourself) in this thread:
1. Easy to Follow
2. Centred around the consumption of organic and unprocessed food
3. Avoid animal flesh if possible
Cutting animal products out of your life is easy. So is living on the nutrient deficient edge of starvation. If you want a balanced diet, and you want to consume enough protein to maintain muscle mass at the very least, it takes just a little bit more thought and a little dedication. If your aim is to reduce body fat % on such a diet while maintaining muscle mass, it's not impossible by any means but living within the strict confines of Vegan beliefs is beginning to make it very unrealistic for someone who lacks motivation and focus. It's not without effort, and requires nutritional planning and forethought on your end (if you want to stay healthy), which is where most come unstuck.
You want results, but you seem to want them to just happen. You need focus. Some diets are much easier to follow, depending on your cultural background and goals. Some prohibit carb rich food as seen in your traditional Asian diet whilst others rely on it. Your success
will depend mostly on two factors: 1) suitability of the chosen diet for reducing body fat (without narrowing the scope of foods that will make up your restricted caloric intake) and 2) Your dedication to following through with learning more about nutrition, tracking your intake and expenditure, researching the values and availability of foods and adapting in general.
Luck in your efforts, Borat. Just remember that if you want to stay committed and lose weight, don't bite off more than you can chew.
