A vegan diet takes care of most of what we need to do. But you'll also want to minimize the use of oils generally because while olive oil and other vegetable oils are better for your heart than chicken fat they are as fattening as animal fats.
It's your outlook on life that counts. If you take yourself lightly and don't take yourself too seriously pretty soon you can find the humor in our everyday lives. And sometimes it can be a lifesaver.
