Description
This study employed a mixed-method approach combining interviews and data from the Measuring Energy Expenditure and Dietary Intake at Different Activity Levels (MEDAL) project. A seven-day food record provided detailed insights into participants' food intake, focusing on protein sources and carbon footprint (CO2e). Participants, aged 18-40, were recruited from Gothenburg University and local sports clubs between October 2020 and April 2021. They were divided into two groups based on their physical activity levels, following WHO guidelines.
Data collection included semi-structured interviews and a seven-day food record using the Nutrition Data online tool. Resting energy expenditure was measured using indirect calorimetry. The interviews explored food shopping habits, dietary preferences, and climate impact considerations without directly informing participants of the climate focus to avoid bias.
Quantitative data were analyzed with statistical tests, while qualitative insights were triangulated with food records to assess climate-conscious and sustainable food consumption practices. The anal

Quantitative data were analyzed with statistical tests, while qualitative insights were triangulated with food records to assess climate-conscious and sustainable food consumption practices. The analysis was guided by social practice theory, focusing on the interplay between participants' attitudes and behaviors. Statistical analysis was conducted using SPSS, and significant findings were determined with a p-value of 0.05 or lower. Show less..

Description of study design
Data were collected through semi-structured interviews and a seven-day food record. All participants were interviewed in connection with completing the food record. Compliant with the aim, the interviews focused on elements related to the carbon footprint of food. An interview guide provided structure, but the questions were open-ended, offering flexibility and undirected answers. The interviews were transcribed verbatim.
The interview protocol was designed to explore participants’ food choices, focusing on the coordination of activities, the stability and repetition of behaviors, the influence of contextual factors, and the dynamic nature of their practices.
Each participant performed a seven-day weighed food record using the online tool Nutrition Data (Nutrition Data Sweden AB, Norsjö., Sweden) version 20.11.11. Each participant was offered a portable scale for weighing food. Participants were encouraged to upload pictures in the Nutrition Data app to clarify their intake. The messaging function was used to send standardised encouraging messages on days three and six to increase compliance. To assess the accuracy of the reported energy intake, it was divided by RMR, and values below 1.2 are considered low energy intake (Black 2000).
Further, the RISE climate database (Florén, Amani, and Davis 2017) in DietistNet (Kost och Näringsdata, 2020) version 1.6 was used to assess CO2e. Finally, protein sources were divided into animal- or plant-based by manually evaluating the food records.
Sampling procedure
• Women (50%)and men (50%) 18 – 40 year of age
• The participant has ability to be compliant to the study protocol with regards to general health.
• High active group at least 300 min of VPA
• Low to medium active group no more than 150 min of VPA
• Signed written informed consent
Exclusion criteria :
• Female patients who are pregnant, lactating or have a desire to become pregnant during the study
• Conditions that might affect BMR such as untreated or poorly controlled hypo- or hyperthyroidism
• Other conditions that are hard to control for like poorly controlled diabetes, unstable heart disease, heart failure, recent stroke/TIA or other similar complications.
• Recent Covid-19 infection or suffering from post-covid symtoms
• Artificial joints or metal elements in their body or wearing a pacemaker.
• Not considered suitable if during assessment judged unable to comply to the study protocol.
