First thought:A diet that calls for HOT DOGS? What's next, the SPAM diet?
Second thought: That is a VERY low calorie plan that is lacking many essential nutrients. I sure would worry about my metabolism slowing down eating that way. Coffee and artificial sweetener as part of a plan worries me too.
Best of luck and if this works for you and meets your personal needs, more power to you!
Personally, I would never do a 'diet' like this, even if I ate those kinds of foods! Have you checked out the Whole Foods/Superfoods section of this board? It's a GREAT, natural and healthy approach to eating!
