How Lock In grades food

Build every meal on

Eggs — whole, yolks included
Liver and other organs, 100–200 g a week
Wild fish and shellfish

Ripe fruit, honey, maple syrup

Keep out

Seed oils — canola, sunflower, soybean, corn, “vegetable oil”, margarine
Fried and restaurant food cooked in them
Refined sugar and syrups
Ultra-processed food and refined flour
Alcohol and artificial sweeteners

Minimise

Grains, legumes, nuts and seeds — plant defence chemicals that block minerals
Raw leafy greens and soy

Every meal you log gets graded against these rules, with warnings and what to eat next.

Nutrition goals

Macros and micros are goals — going over is fine, no warnings. Seed oils, omega-6, refined sugar and anti-nutrients are limits — the app warns you when a day goes over.

Micronutrient goals

Defaults are the official daily recommendations for your age and sex. Blank = default.

Limits: seed oils, omega-6, sugar & anti-nutrients

Seed oils stay at zero. Omega-6 (linoleic acid) 7 g and refined sugar 15 g a day. Oxalates 40 mg (clinical low-oxalate diet), phytates 400 mg (keeps zinc absorbing well), solanine 0.1 mg/kg and cyanide 0.02 mg/kg bodyweight (EU food-safety thresholds); the rest are set at low everyday intakes. Blank = default.

Gyms

Machines differ between gyms, so weights and progress are tracked per gym. Pick the gym at the top of the Lift tab.
