Human effect (acute, controlled). In a lab study (n = 15), 25 min of 3G handset exposure led to a ~27% increase in ad‑libitum energy intake, weighted toward carbohydrates, versus sham. The authors interpreted the behavior as the brain acting “as if low on energy” despite unchanged whole‑body status. This is a rapid, functional outcome consistent with altered neural energy‑sensing and autonomic tone under sub‑thermal RF exposure.

Mechanistic link to S4 timing fidelity.

Pulsed RF‑EMF → ion forced oscillation (IFO) at the membrane imposes periodic electrostatic forces on S4 voltage sensors in VGICs, reducing timing fidelity of channel gating without heating. (Mechanistic kernel.)

Hypothalamic nutrient‑sensing neurons (glucose‑excited/inhibited) rely on L‑type Ca²⁺ channels and precise Vm dynamics. Small S4‑driven shifts in open probability and activation kinetics bias firing rates and neuropeptide output, moving appetite and food‑choice set‑points toward “energy‑deficit.”

Mitochondrial coupling. Recurrent Ca²⁺ waveform distortion raises respiratory workload and ROS signaling; in vivo, repeated head‑only sub‑thermal 5G‑NR exposure up‑regulated 10/13 mtDNA‑encoded OXPHOS genes in mouse cortex—molecular evidence of elevated oxidative phosphorylation demand under realistic signaling structure.

Why this integrates with the broader storyline.
-
The same upstream S4 timing‑fidelity loss that explains nerve/heart vulnerability (high VGIC/S4 and mitochondrial density; animal convergence on gliomas and cardiac schwannomas) also explains metabolic drift: altered hypothalamic set‑points, autonomic balance, and reward valuation for carbohydrate‑dense foods.

This is a pattern‑of‑exposure phenomenon. Duty cycle, burst structure, and low‑frequency components in the near field govern the biological effect more than the carrier generation label.
Where EHS fits. Individuals labeled “EHS” can be understood as a sensitivity phenotype with lower thresholds for detecting signaling error—transient Vm/Ca²⁺ irregularities and their autonomic/metabolic correlates. That awareness can be protective: it prompts exposure control before redox and inflammatory programs harden into persistent load. In this framing, EHS is an early‑warning capacity, not a defect.
Testable predictions (useful for readers and reviewers).
-
Short RF exposures that increase carbohydrate‑weighted intake should co‑vary with shifts in heart‑rate variability, pupil dynamics, or EEG spectral power indices of hypothalamic/brainstem autonomic output—without thermal rise.
-
Protocols that flatten pulse structure or reduce duty cycle/peak‑to‑average ratio should attenuate the feeding effect at the same average power.
-
Individuals who self‑identify as EHS should show larger effect sizes at lower incident fields, consistent with a left‑shifted channel/mitochondrial threshold.
One‑sentence takeaway. The metabolic finding—more carbohydrate intake after brief RF exposure—fits the S4 timing‑fidelity mechanism: pulsed fields perturb VGIC gating, bias neural energy‑sensing and autonomic tone, increase mitochondrial drive, and manifest as rapid, sub‑thermal changes in appetite and fuel selection.
