Evaluation of the "Eat Less Meat" One-month Challenge

In a context where meat consumption should be dramatically reduced in western countries to improve both population and planet health, the "Eat Less Meat" one-month challenge is a new behavioural intervention that aims (i) to weaken meat consumption habit and (ii) to enhance intrinsic motivation to eat less meat to trigger long-term reduction in meat consumption. The present study focusses on the quantitative evaluation of the effect of this challenge on French university student's meat consumption. Parallel two-arm randomized controlled trial with repeated measures (online questionnaires) pre-, during- and post-intervention. All the participants will be recruited to take part in the "Eat Less Meat" challenge for one month. Participants in the control group will take part in the challenge 4 months after the participants in the intervention group. Participants in both groups will complete the online questionnaires at the exact same time, i.e., pre-, during- and post-intervention measures will take place before the control group starts the challenge.
