I think Michael said that IF does not provide similar benefit as CR unless the eating days in IF is also calorie restricted. Also, I haven't read an article saying the benefits of MR is similar to CR. What I read was that it could be MR that's making CR benefits possible.
Vegan diet is not automatically "good for life extension and health in general" (tofu, vegan cakes, ice cream, ramen noodles, taters, lots of processed food, cooked food, gmo products, etc) and not always "low in methionine". (brazil nuts, grains) So when someone says she's vegan, she could be living off ramen noodles and pepsi.
Raw Vegan diet on the other hand is a truly God-sent to life extensionists as it fixes many of the problems in a regular vegan diet. First, Raw Vegan eliminates all grains which achieves the low-methionine goal, takes off all processed food, yes including tofu, prepacked food, frozen food, cooked food which lowers your AGE intake, baked goods and all other vegan crap in the supermarket. Raw Vegan diet is also all organic, all natural plant based diet.
So my diet is CR, raw vegan. Give it a try, in just 6 months, you'll look 10 years younger.
