Fats burned fast, turning partly into ketones — fuel for brain and muscle. Small thinking-score gains appear where memory is already slipping, and strength gains in the very frail; midlife is untested. Loose stools fade with slow escalation. Blood fats depend on what the oil replaces: favorable against butter, not olive oil. Added rather than swapped, simply extra calories. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Fasting triglycerides | 50–90 mg/dL | The lipid most consistently raised |
| ApoB | <80 mg/dL, <60 if high cardiovascular risk | Counts atherogenic particles directly |
| LDL cholesterol | 70–100 mg/dL | Rises when these fats displace unsaturated oils |
| HDL cholesterol | ≥50 mg/dL in men, ≥60 mg/dL in women | Rises relative to long-chain saturated fat |
| Fasting insulin and HOMA-IR | Insulin 2–5 μIU/mL; HOMA-IR below 1.5 | Tracks the insulin-sensitivity signal seen in overweight adults |
| HbA1c | 4.8–5.4% | Confirms no glycemic drift from the dietary change |
| Capillary beta-hydroxybutyrate | 0.3–1.0 mmol/L at 60–120 minutes post-dose | Confirms the dose is actually producing ketones |
| ALT | 10–26 U/L in men, 10–19 U/L in women | Screens for hepatic strain at high habitual intake |
| hs-CRP | Below 1.0 mg/L | Baseline for the unproven inflammatory claim |
| Body composition | No established target; track change from the individual's own baseline | Distinguishes fat loss from lean-mass loss |
| Grip strength | ≥35 kg in men, ≥20 kg in women | The function endpoint the frailty trials moved |
Cadence: Capillary ketone check 90 minutes after a dose during the first week; full lipid and metabolic panel at 8–12 weeks, then every 6–12 months while intake continues; body composition and grip strength at 12 weeks, then annually.
