Abstract
People taking part in commercial treks are exposed to high altitude (HA) while eating ad libitum, a situation that has been related to under eating and body weight loss. We investigated this phenomenon in westerners taking part in a typical Himalayan trek. Body weight, energy intake (EI), macronutrient composition of the diet, and acute mountain sickness symptoms (AMS) were measured in seven healthy individuals (aged 45 +/- 12 yr and BMI 24.6 +/- 4.4 kg/m(2)) during a 19-day trek to Makalu Base Camp. Comparisons were made between three periods of the trek: a 5-day climb below 2500 m (low altitude 1: LA1), an 8-day period between 3500 m and 5200 m (high altitude: HA), and a 4-day descent below 2500 m (low altitude 2: LA2). Body weight was significantly reduced at the end of the trek (p < 0.01). A decrease in total EI was observed at HA (p < 0.05). This was followed by an increase in EI upon return to LA2 (p < 0.001). Neither EI nor macronutrient composition of the diet was associated with the presence of AMS. In conclusion, a decrease in EI was observed in HA, which does not seem to be macronutrient specific.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
