Effects of Age and Sex on Weight-Loss Dynamics in Obese Patients Undergoing Very Low Calorie Treatment
Bibliographic record
Abstract
Background and Significance: Although known to effectively provoke large scaled weight-loss, less is known regarding age- and sex-related influences on treatment outcomes of bariatric patients treated with a very-low calorie diet (VLCD) program. Purpose: This study retrospectively examined body composition and metabolic changes induced by a 12-wk proprietary VLCD treatment in obese patients while assessing age and sex differences. Methods: Male (n=16) and female (n=16) patients underwent 12 weeks of VLCD under standard medical care. Results: Older patients exhibited a greater relative loss of FFM compared to younger patients (p=0.004). Older patients also lost a greater proportion of total weight-loss as FFM (p=0.003) and lower proportion as FM (p=0.003) compared to the young group. This age-specific difference in weight-loss composition was driven by the older males. Conclusion: The results demonstrate the need for special clinical considerations for VLCD treated patients, such as older adults and perhaps older males specifically, who demonstrate a reduced quality of weight-loss compared to their younger counterpart.

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.
