Mobilize, Capture, Do Not Spill. A fasted interval-primed low-intensity aerobic protocol for targeting visceral and ectopic lipid flux in insulin-resistant phenotypes

This record contains a hypothesis-generating exercise-nutrition protocol manuscript titled **“Mobilize, Capture, Do Not Spill: A fasted interval-primed low-intensity aerobic protocol for targeting visceral and ectopic lipid flux in insulin-resistant phenotypes.”**

The manuscript proposes a mechanistic training strategy for insulin-resistant phenotypes, type 2 diabetes risk states, metabolic syndrome, visceral adiposity, and ectopic lipid burden. The central principle is:

**Do not optimize lipolysis alone. Optimize the temporal coupling between fatty-acid release and skeletal-muscle oxidative disposal.**

The proposed protocol combines:

1. an overnight fasted state,
2. a short high-intensity interval primer,
3. a prolonged very-low-intensity FatMax-oriented aerobic capture block,
4. and a post-exercise low-insulin window without carbohydrate or rapidly absorbed protein.

The paper frames this sequence as a falsifiable “mobilize-capture-do-not-spill” model: liberated fatty acids are therapeutically useful only if they are captured and oxidized rather than re-esterified or redistributed into ectopic lipid pools.

The manuscript is explicitly presented as a hypothesis and protocol paper, not as an established clinical recommendation. Its evidence base is modular: exercise interventions can reduce visceral and hepatic fat in type 2 diabetes; fasted aerobic exercise increases acute fat oxidation relative to fed exercise; carbohydrate ingestion can suppress lipolysis and fat oxidation during exercise; FatMax can identify individualized intensities for maximal fat oxidation; and post-exercise protein timing creates a trade-off between anabolic recovery and the proposed low-insulin lipid-flux window.

The unproven claim is that the exact temporal sequence described here outperforms matched conventional aerobic exercise, interval-only exercise, or low-intensity exercise alone for reducing visceral and ectopic lipid burden. Therefore, the manuscript proposes an 8–12 week randomized pilot trial with imaging, metabolic, and exercise-physiology endpoints.

The protocol is conceptually linked to the **War Map Framework**, where impaired adipose expandability and lipid-buffering failure are treated as candidate sub-regressors: observable, modifiable, causally material biological state variables that may need to be directly measured, perturbed, and verified during attempts at mechanistic disease reversal.
