This section of the forum tends to be very quiet, so you will find some poor soul who's eating 1000 calories a day and still not losing wondering if they're "doing it right", yet getting no response. Clearly the answer is "NO!", but very often the person's post goes unanswered. That's when I may chime in. No, I'm not an "expert" (meaning I don't practice fitness and diet as my profession), however, I am an intelligent and well-read individual who has worked hard to maintain my weight and lose weight at times over the years. So I have my own experiences, and frankly, just like the "experts", I can also read articles about the science.
Some questions (such as the 1000 calorie diets or the cabbage patch starvation soup diet) simply do not require any specific expertise to respond appropriately, just a bit of basic nutritional knowledge and some common sense to help the poster (usually a desperate teenager) avoid a frustrating future of yo yo dieting. Sometimes the problems posed are less clearly resolved, and that's when I would step off and hope the "experts" will respond.
I also believe that, despite the comment that any wrong answer (such as "go on the cabbage soup diet") is a waste of time, that these wrong answers are always debated by others and actually give the readers a chance to see why that's the wrong way to go. Wrong answers, if debated, can be very educational.
Note that sometimes the experts' grammar and spelling is poor/wrong, and it makes you wonder how educated they really are.
To sum it up, my vote would be to (a) either open the forum up to everyone, the so-called experts and the lay person or (b) limit this forum to only the self-described experts AND open a new forum that is for general support and allows everyone to respond. Why waste the knowledge of so many people who really want to help just because they may not do nutrition/fitness for a living?
Hope this quick response is coherent.
