Going Vegan

After a lifetime of the basic North American diet i'm left at 66yrs old fat sick and nearly dead.100lbs overweight,diabetic,mobility issues and a couple of cheese burgers away from a heart attack, As with most people i know breakfast ,lunch and dinner consisted basically of some form of meat smothered in cheese wrapped in white bread usually accompanied with deep fried potatoes and a mug of fizzy sugar water,
About a month ago i tripped over a PBS infomercial by a Dr Joel Fuhrman espousing the benefits of a plant based dietary lifestyle,i figured i got nothing to lose so i bought the book and have now become a vegan,
To date i've lost 15lbs,cut my diabetic medications in half and generally have much more energy.
Any one else derived improved health by going to a more vegetable based dietary lifestyle?
