I was checking out weight loss products in Clickbank and came across a new one (to me). I opted-in to their affiliate list and they provide a great affiliate guide covering the weight loss niche, talking about the target audience, "hot" article topics with keyword phrases and, on page 21, a link to a spreadsheet with over 5000 dieting related keywords.
You have to opt-in to their list (through Aweber), but, of course, you always have the option of unsubscribing after. (But if they provide such great information, it would be well worth it to stay on the list, IMHO.)
Here's the link to the affiliate page:

Again, I have no relationship to this product, don't know who owns it, etc. (it appears to be a Fat Loss 4 Idiots clone, but I could be wrong). I just want to pass the info along for those in the weight loss niche or thinking of jumping into it.
