Lifestyle Tips
Salt everything generously — you need 3-5g sodium daily on keto
Fat adaptation takes 2-6 weeks — electrolytes manage symptoms during transition
Track net carbs (not total) — fibre doesn't count
Include organ meats or a quality multivitamin to prevent micronutrient gaps
Test ketone levels initially to ensure you're actually in ketosis
