I saw the video last night and now I am very confused.It didn't help to find out that Dr.V.Keys lived to be 100 and his wife 97.I have changed my woe completely to low carb,only struggeling with portion size,but experimenting how to get it right,and now this.These vegan guys look pretty good for their age and I am now over 50,still trying to figure it all out.I don't think I could go vegan,it's all too complicated and time consuming and I love the simplicity of lc.I do feel good on it as well,sleep well etc.but the video and its message gave me a disturbed night sleep.I doubt,all of a sudden.What,if I got it all wrong and they have found the solution....I need this forum more than ever.Thanks for being there.
