Abstract
The study focuses on the eating habits and nutrition of the pupils aged 11-15 years. It provides a detailed analysis of children's daily routines, including eating patterns, hydration, physical activity, sleep duration, and screen time. Particular emphasis is placed on the potential impact of school meals on the regularity, variety and quality of children's diets and its possible role in the prevention of overweight and obesity. The main objective was to investigate the extent to which school meals influence children's lifestyles and whether there are differences between those who eat at the school canteen and those who do not. The research was conducted through a questionnaire survey among six primary schools and students from five multi-year grammar schools in the Olomouc Region. The results showed that school meals contribute positively to the regularity of children's eating habits. Children attending the school canteen usually eat five times a day, compared to their peers who do not eat school meals, with a quarter of them eating only 1-2 times a day. When average weight was measured, it was confirmed that children who eat in the school canteen weigh on average 2.23 kg lower body weight than children who do not eat the school canteen. Two-thirds of respondents were found to have lack of...

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
