No of course not! Hence my mention of 'thought exercise' -- I'm trying to spur discussion, get some other peoples' input, and explore an idea.
My initial instinct was "awesome! health and low body fat for everyone!" I'm a perpetual optimist, but one of the most valuable skills I've learned as I've gotten older is the recognition that there's always _some_ con to the pro, and I think one of the valuable things about a community (and a discussion) is the exercise of looking at all sides of topic.
(Which, btw, you've provided, even if unintentional ;)
