A whole-food pattern keeping meat, fish, eggs, vegetables, fruit, roots, and nuts and removing grains, dairy, legumes, refined sugar, and added salt. Short-term gains in body fat, waist size, blood pressure, blood fats, and blood sugar are reliable, largest in the first six months, and fade as people drift from the pattern. Iodine and calcium fall unless replaced. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Apolipoprotein B | Below 80 mg/dL; below 60 mg/dL if cardiovascular risk is already elevated | Counts the particles that drive artery disease |
| Hemoglobin A1c | 4.8–5.4% | Average blood sugar over three months; the primary efficacy marker |
| Fasting insulin | 2–5 µIU/mL | Detects insulin resistance years before blood sugar rises |
| High-sensitivity C-reactive protein | Below 0.8 mg/L | Tracks background inflammation, where the diet's effect is conflicted |
| Spot urinary iodine concentration | 100–199 µg/L | The single deficit this diet reliably produces |
| Thyroid-stimulating hormone | 0.5–2.5 mIU/L | Detects thyroid consequences of falling iodine |
| 25-hydroxyvitamin D | 40–60 ng/mL | Bone and immune status once dairy is removed |
| Serum calcium with intact parathyroid hormone | Calcium 9.0–10.0 mg/dL; parathyroid hormone 15–30 pg/mL | Rising parathyroid hormone is the earliest sign of calcium shortfall |
| Ferritin | Men 50–150 ng/mL; women 40–120 ng/mL | Detects iron loading from red meat or iron loss from grain removal |
| Estimated glomerular filtration rate with blood urea nitrogen | eGFR above 90 mL/min/1.73 m²; blood urea nitrogen 10–18 mg/dL | Watches the kidney load from sustained high protein intake |
| Serum uric acid | 3.5–5.5 mg/dL | Flags the stone and gout risk that accompanies high protein and organ meat |
| Lean body mass by dual-energy X-ray absorptiometry | No established target for change; tracked against own baseline, any fall a signal | Detects muscle loss during rapid fat loss without resistance training |
| Seated blood pressure | Below 120/80 mm Hg | The fastest-moving benefit and the fastest route to over-medication |
Cadence: Blood pressure and home glucose weekly in month one on glucose-lowering or antihypertensive medication; full panel at three and six months, then six- to twelve-monthly; body composition at six and twelve months.
