logic approach. >> the bottom line, if you were drinking diet or regular soda, you had a choice of the two, for you or your patient what would you recommend? >> well, from a health perspective neither say good option. but if we're talking about weight, i would still go with the diet soda unless you find your doing all the right things and very resistant to weight loss or at high risk of stroke or diabetes, i really would discourage you from having any of them. you can even try a diet soda swedened with stevia which may turn out to be a better option. >> and water's always a good option, i know you say as well. >> of course, water would be my first choice, water, green tea, coffee which actually has favorable effects on disease outcomes. >> we'll have you back to talk about that sometime soon. thanks, doc. >> thanks. doctors and patients, they complain all the time about red tape and about insurance
