Profile

Nutrition goals

Macros and micros are goals — going over is fine, no warnings. 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.

Anti-nutrient limits

Strict defaults: 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.
