You're making it way too complicated. You need oils, fats and animal protein in your diet. Vegan diets can be very dangerous unless you don't know exactly what you're doing. Eat what you like to eat but if you want to keep the weight off and avoid sugar (even in fruit/alcohol), white rice. white potatoes and anything with white flour in it as much as possible. Also be physically active as much as possible.
I read that vegetarians live 2-3 years longer than meat eaters.
The only animal products that do NOT have a longevity penalty are eggs and fish. (Frequent) red meat has the highest penalty, due to the by products created by our digestive process.
I eat lots of eggs, lots of fish, and a fair amount of other animal protein. Life's too short to live without a good variety of beef, deer, elk and pork....
I mean, give up bacon for a few weeks more life? Get real......
