=== (key actives commonly include isomaltulose (low-GI carb), resistant maltodextrin (resistant dextrin), allulose, MCT oil, plant protein) ===
* Post-prandial glucose & insulin excursions ↓ (lower peak and iAUC vs sucrose/high-GI carbs) Measure: CGM metrics around shakes; standardized meal tests Why: isomaltulose has a slower digestion rate (low GI), allulose attenuates glycemic response, and viscous/resistant fibers slow absorption.

* Visceral fat ↓ small but measurable over ~12 weeks with resistant dextrin in some studies Measure: CT/DEXA visceral fat estimates; waist circumference Why: increased fermentation/SCFAs and improved satiety/glycemia.

* Ketones (β-hydroxybutyrate) ↑ transiently after doses with MCT Measure: finger-prick/urine breath ketone meters 1–3 h post-intake Why: MCTs rapidly convert to ketones in the liver (acute effect; not a 90-d chronic change). (General physiology; no single citation.)
