The bars aren't science, it's basic nutrition and she's pretty much making another "version" of the power bar among others that are already out there (no I never said the exact same bar).
The difference is she can market them easier with her position in running and that's not rocket science at all. If you boneheads don't think that her sudden blog, asklaurenfleshman was just a coincidence, then I've got dozens of islands to sell you in the Caribbean!!!!!!!!!
They did NOT start making and selling these overnight. The blog is part of the marketing and anyone in marketing and a little common sense knows what I'm saying. Get followers and then BINGO, you just happen to have a product and a certain percentage of people will buy because you are so great and took the time to answer their beginning runner questions. These bars were in the making for awhile, trust me.
I may be wrong, but I swear I read where she was asked to remove her self-promotion advertisement last year before the NYC Marathon and I recall one of the brothers writing about it on the home page.
