Participants in this arm engage in an 8-week program that integrates mindful eating and mindful movement practices into their regular physical education classes. Each class includes a 10-minute mindful eating practice focused on enhancing awareness of hunger and fullness cues, sensory experiences of food, and emotional responses to eating. Following this, the final 10 minutes of each class are dedicated to mindful movement exercises, which combine physical postures and movement with mindfulness techniques to promote food literacy, physical literacy and social emotional competencies.

Standard Physical Education Participants in this arm continue with their regular physical education classes as usual, without the integration of any mindfulness practices. This control arm involves the standard activities and curriculum designed for physical education classes at the university, which may include a variety of physical exercises, sports, and theoretical instruction related to health and fitness.

This intervention integrates mindful eating practices and mindful movement into physical education classes for a duration of 8 weeks.

Each session begins with a 10-minute mindful eating practice designed to enhance participants; awareness of hunger and fullness cues, the sensory experience of eating, and their emotional responses to food. The program is to address food literacy, physical literacy, and social-emotional learning. It applied the principles of various established mindfulness and cognitive behavioral therapies and the book "The Joy of Half a Cookie: Using Mindfulness to Lose Weight and End the Struggle with Food" . It is grounded in the components of Mindfulness-Based Eating Awareness Training. The movement practices include basic poses in pairs and groups, and breath awareness techniques to facilitate a mindful connection with physical sensations and mental states.

Improvement in food literacy knowledge will be assessed using the Food Literacy Evaluation Questionnaire (FLEQ-Ch). This 15-item questionnaire is structured into three main dimensions: Planning and Management, Selection, and Preparation. It evaluates participants' knowledge related to making informed food choices. Participants respond to each item using a 4-point Likert scale ranging from 0 (Never) to 3 (Always). The total score ranges from 0 to 45, with higher scores indicating higher levels of food literacy.

Improvement in mindful eating behaviors will be assessed using the Mindful Eating Questionnaire (MEQ), designed by Framson et al. (2009). This 28-item questionnaire evaluates eating behavior across five subscales: Awareness, Distraction, Disinhibition, Emotional Response, and External Cues. Participants rate a 4-point Likert scale from 1 (never/rarely) to 4 (usually/always). The total MEQ score is calculated as the average of all subscale scores, ranging from 28 to 112. The higher the score, the higher degree of mindful eating behavior.

Improvement in food literacy will be assessed through 24-hour dietary intake records. This metric evaluates participants' ability to maintain balanced eating habits. The 24-hour dietary intake will be measured each time on the day of the mindfulness session and on the days when participants complete the questionnaires.

Enhancement in physical literacy will be assessed using the Perceived Physical Literacy Instrument (PPLI). This instrument consists of 9 items across three subscales: Knowledge and Understanding, Self-Expression and Communication with Others, and Sense of Self and Self-Confidence. The Knowledge and Understanding subscale evaluates participants' attitudes and awareness of the health benefits of sports. The Self-Expression and Communication with Others subscale evaluates participants' social skills and confidence in natural environments. The Sense of Self and Self-Confidence subscale evaluates participants' physical fitness and self-management skills. The instrument consists of 9 items that are rated on a 5-point Likert scale, ranging from 1 (strongly disagree) to 5 (strongly agree). The total score for the PPLI ranges from 9 to 45, with higher scores indicating higher levels of perceived physical literacy.

Improvement in emotional regulation will be assessed using the Difficulties in Emotion Regulation Scale Short Form (DERS-SF). This metric evaluates participants' abilities to regulate their emotions effectively. Participants rate each item on a 5-point Likert scale, indicating how often the items apply to them, from 1 (almost never) to 5 (almost always). Each subscale score is computed as the sum of its corresponding items, with the total DERS-SF score calculated by summing all 18 items. This results in a range from 18 to 90, with higher scores indicating greater difficulties in emotion regulation.
