Like you said, you could have gotten more than 12 people from this very thread who would be interested in being part of a study, that is another thing that makes me very skeptical as well. A 12 person study is as good as anecdotal.
According to google roughly 10% of the US population are doing intermittent fasting(which is much higher than I would have thought(good job people)). That is roughly 33 million people. Imagine how much money in sales that is costing the food industry.
