- People with Type 1 diabetes or insulin-dependent Type 2 diabetes
- People taking prescription medications that require food intake

Accuracy of Estimates
FastingCalc uses validated scientific formulas including the Mifflin-St Jeor equation for BMR estimation and established biological research for milestone timings (ketosis onset, autophagy activation). However:
- All results are population-based estimates — individual variation is significant
- Ketosis and autophagy timelines vary by metabolic rate, glycogen stores, activity, and genetics
- Calorie estimates should not be used as the sole basis for medical nutritional planning
