Primary |
Change from Baseline Meat consumption at 1 month (during intervention) |
Meat daily intake (in grams) will be calculated by summing daily intake for all the items of the food frequency questionnaire that fall into the meat category. |
20 minutes, repeated measures (online food frequency questionnaire): baseline and month 1 |
|
Primary |
Change from Baseline Meat consumption at 4 months (3 months after intervention) |
Meat daily intake (in grams) will be calculated by summing daily intake for all the items of the food frequency questionnaire that fall into the meat category. |
20 minutes, repeated measures (online food frequency questionnaire): baseline and month 4 |

Secondary |
Change from Baseline Adherence to the French dietary guidelines at 1 month (during intervention) |
Adherence to the French dietary guidelines will be evaluated using the simplified PNNS-GS2. The sPNNS-GS2 builds on the distinction between malus components (less healthy food groups which consumption should be limited, carrying a negative score, i.e., red meat, processed meat, sugary foods, sweet-tasting beverages, alcoholic beverages, salt) and bonus components (healthier food groups carrying a positive score, i.e., fruits and vegetables, nuts, legumes, whole-grain food, milk and dairy products, fish and seafood) reflecting established knowledge on the relationship between food groups consumption and non-communicable disease risk factors. sPNNS-GS2 will computed for each participant (range: -17 to 11.5, with higher scores indicating better adherence to the French dietary guidelines). |

Change from Baseline Greenhouse gas emissions at 1 month (during intervention) |
Greenhouse gas emissions (GHGEs) will be calculated by multiplying the daily intake of each food item by its associated GHGEs per kg |

Secondary |
Change from Baseline Meat consumption habit at 1 month (during intervention) |
The Self-Report Habit Index will be computed by averaging ratings for all the 12 individual items from the Self-Report Habit questionnaire. Responses will be reported on a 6-point scale anchored by 'strongly disagree' and 'strongly agree' from 1 to 6. The scores will be coded such that high values indicated strong habits. |

Secondary |
Change from Baseline Food choice motives at 1 month (during intervention) |
The food choice questionnaire (FCQ) includes 30 items and 10 subscales: health, mood, convenience, sensory appeal, natural content, price, weight control, familiarity, ethical concern and animal welfare. Answers to each item will range from 1 to 4: 1 = Not at all important; 2 = A little important; 3 = Moderately important; 4 = Very important. A score for each motive will be computed by averaging ratings for the three individual items in each of the ten subscales, higher scores indicating higher importance. |
