the diet is working good for me. My parents decided to try it out. this worries me a little, i must admit. they are 58, and 59. they are both in decent health except they could both loose about 75 pounds. My dad has smoked all his life, and my mom has high blood pressure. Is this a safe thing for them to just jump into like I did at 25 years old? I would hate for them to try the new program , and getted screwed up. anybody have any good advice for me?
