Researchers at Universidad Andrés Bello and international partners employ supervised machine learning, notably a tuned random forest classifier, trained on anthropometric indices derived via multifrequency bioelectrical impedance. The model achieves 84% accuracy and 0.947 AUC-ROC in classifying normal, high, and very high fat levels, with SHAP highlighting fat mass and fat-free mass indices as key features.

Key points

  • Random forest on six BIA-derived indices (BMI, FMI, FFMI, SMI, MMI, TBW) achieved 84.2% accuracy and 0.947 AUC-ROC in obesity level classification.
  • SHAP and recursive feature elimination identify FMI, FFMI, and BMI as the top predictive features driving model decisions.
  • Ensemble tree-based models (random forest, gradient boosting) outperform SVM, logistic regression, k-NN, and decision tree in multiclass fat-level classification.

Why it matters: Combining interpretable AI with bioimpedance-derived body composition metrics enhances obesity detection, supports personalized screening, and informs targeted public health strategies.

Q&A

  • What is bioelectrical impedance analysis (BIA)?
  • How does SHAP interpret machine learning models?
  • Why is fat mass index (FMI) a key predictor?
  • Why choose random forest over SVM or logistic regression?

The longevity race: Could we really live to 150?

NOVOS Labs presents four science-based biohacks—multi-ingredient supplementation, structured exercise, optimal hydration, and consistent sleep—designed to address key cellular aging mechanisms. By combining compounds that target inflammation and senescence with practices that promote autophagy, mitochondrial health, and glymphatic clearance, these strategies aim to improve biological age markers and extend healthspan.

Key points

  • Calcium alpha-ketoglutarate extended lifespan and improved healthspan in aged mice by modulating inflammation and mitochondrial energy pathways.
  • High-intensity interval and strength training stimulate autophagy, mitochondrial biogenesis, and myokine release, enhancing VO₂ₘₐₓ and reducing oxidative stress.
  • Combined hydration protocols and a plant-forward, polyphenol-rich diet preserve cellular homeostasis, stabilize insulin signaling, and support gut microbiome diversity.
