This looks like an ambitious project to create an extensive database of health and lifestyle info on 1,000,000+ subjects.
I expect it could be used to help researchers answer pressing complex questions like:
What advice is most effective to counter obesity, diabetes and heart disease?
A. restrict saturated fat
B. restrict red meat
C. eat vegan
And with good representation from our community they might discover the answer is
D. none of the above
The sign up process is a little tedious but hopefully enough keto’ers can spare the time to create a signal able to be seen by the most myopic of researchers.
