Paleo Diet for Health & Longevity

Created on 10/25/2026 – Quick Reference based on Evidence Review created using AI4L / Opus 5.5 – Audit

The paleo diet, an eating pattern of meat, fish, eggs, vegetables, fruit and nuts without grains, beans and lentils, dairy, added sugar, salt or processed foods, has possible relevance to weight, heart health and blood sugar. Short studies, clearest with excess weight or early blood-sugar problems, show more weight loss, lower blood fats and somewhat lower blood pressure, gains shrinking over two years. Strict versions risk iodine and calcium shortfalls. (Full Review)

Protocol

Core template (Cordain)
Lean meat, fish, eggs, vegetables, fruit, nuts
Excludes grains, legumes, dairy, added sugar, salt and refined oils
Research macronutrient regimen (Umeå)
30% protein, 40% fat, 30% carbohydrate
Share of energy, unrestricted quantity; dairy, cereals, added salt and refined fats excluded
Flexible template (Kresser)
Adjustable template, not fixed rules
Leaves room for individually tolerated foods such as some dairy
Time to effect
Blood pressure, triglycerides, cholesterol
Within 2 weeks
Netherlands trial by Boers et al., 2014
Liver fat
By 6 months
Advantage over a low-fat diet gone by 24 months
Glucose tolerance
Within 12 weeks
Improved more than on a Mediterranean-like diet in people with heart disease

Benefits

Contraindications
  • People with non-dialysis chronic kidney disease stages G3–G5 (eGFR below 60 mL/min/1.73 m²)
  • Pregnant or breastfeeding women not taking an iodine supplement
  • People with a current or past eating disorder
  • People with osteoporosis who cannot replace dairy calcium from other foods or supplements
Key Interactions
  • Warfarin, other vitamin K antagonists (acenocoumarol): weaker clot prevention
  • Lithium: rising lithium levels and toxicity
  • Insulin and sulfonylureas (glimepiride, glipizide) (theoretical): low blood sugar
  • Antihypertensives (amlodipine, hydrochlorothiazide) (theoretical): low blood pressure and dizziness
  • Potassium-raising drugs: ACE inhibitors (lisinopril), ARBs (losartan), spironolactone (theoretical): high blood potassium
  • Over-the-counter NSAIDs (ibuprofen, naproxen) and potassium-chloride salt substitutes (theoretical): high blood potassium
  • Multi-supplement regimens: nutrient toxicity
  • Additive supplements (theoretical): low blood sugar (berberine, chromium), low blood pressure (garlic extract, potassium) or high blood potassium
  • GLP-1 receptor agonists (semaglutide, tirzepatide) (theoretical): accelerated lean-mass loss
  • Exercise: complementary effects

Risk & Side Effects

  • High:
  • Medium: Iodine deficiency
  • Low: Lean mass loss without resistance training; low calcium intake and potential bone loss; ketoacidosis during breastfeeding on very-low-carbohydrate versions; colorectal cancer risk from red meat
  • Speculative: Less resistant starch and higher TMAO; kidney stone formation

Monitoring

Marker Target Why
Body weight and waist circumference No established target: track change from own baseline Expected to fall
Blood pressure Not specified in the ER Expected to fall
Fasting triglycerides No established target: track change from own baseline Expected to fall
LDL cholesterol No established target: track change from own baseline Safety check: a rise prompts a change in fat sources
HbA1c and fasting glucose HbA1c 4.0–5.6%; fasting glucose 70–99 mg/dL (standard reference range) Expected to change in insulin resistance
Thyroid-stimulating hormone (TSH) 0.4–4.0 mIU/L (standard reference range) Safety check for iodine deficiency
Urinary iodine concentration No established target: track results against WHO's population adequacy cutoff of 100 µg/L Safety check for iodine deficiency
Serum potassium 3.5–5.0 mmol/L (standard reference range) Safety check for high blood potassium
eGFR No established target: track change from own baseline Safety check for protein load
Bone mineral density (DXA) No established target: track change from own baseline Safety check for calcium shortfall
INR No established target: track stability against own prior values Safety check for vitamin K interaction

Cadence: Baseline before starting; a check at 6–12 weeks, then every 6–12 months while the diet continues; bone density every 2 years where measured; closer checks in the first 2 weeks are common practice for people on insulin, sulfonylureas, lithium or warfarin.

Qualitative Assessment

  • Satiety between meals and absence of cravings
  • Energy levels across the day and during training
  • Digestive comfort and stool regularity after removing and reintroducing foods
  • Training performance, particularly in high-intensity sessions
  • Sustainability: ability to follow the pattern socially and while traveling
