Thanks Björn! Really interested in the diet change interventions. Veganuary has probably also had quite a nice spillover effect through corporate engagement with the challenge (wether solicited by veganuary or not). During the month of January, supermarkets and brands tend to allocate more resources on marketing, product development and deals for plant based products.
To me, this write-up would have been a lot more useful if it ended with a rough cost-effectiveness analysis and any takes on what funders should be excited to fund.
Some other thoughts: I’m sceptical that every 6 extra sign ups to a challenge will get someone from an average diet to an almost plant based diet for a duration of more than 2 years. Is that what the 15% suggests? How were the RCT’s performed? Were random people selected and given an incentive to participate?
Hi Martijn! I completely agree about cost-effectiveness analysis. This wasn’t part of the original research question, but I am hoping to look into that in a Stage II analysis later this year or early next year, pending funding. That would give even more helpful data to the community.
Regarding the RCT, here is a link to the original resource: Impact of 10 Weeks to Vegan. Something to keep in mind is that the sample was people who were already thinking about veganism somewhat (analogous to the contemplating stage of the TTM: Social & Psychological Barriers to Veganism—Bryant Research). Therefore, we need to keep in mind that certain interventions are more likely to work on individuals at different stages in the pipeline (another research study I’m interested in conducting).
