Medical Disclaimer: This calculator provides estimates for educational purposes only and does not constitute medical advice. Intermittent fasting is not appropriate for everyone. Do not fast if you are pregnant or breastfeeding, under 18 years of age, have a history of eating disorders, or have been diagnosed with Type 1 diabetes. If you take medications (especially insulin or blood pressure medication), have any chronic health conditions, or are recovering from surgery, consult your physician before beginning any fasting protocol. If you experience chest pain, fainting, persistent dizziness, or heart palpitations during a fast, stop immediately and seek medical attention.
Enter your current weight, goal weight, height, age, sex, and activity level. Then select your fasting protocol (16:8, 18:6, 20:4, or OMAD) and specify whether you plan to combine fasting with a caloric deficit. The calculator estimates your daily energy expenditure, applies the fasting-related caloric reduction, and projects a realistic timeline to reach your goal weight.
For the most accurate results, be honest about your activity level. Overestimating exercise will inflate your calorie burn estimate and produce an overly optimistic timeline.
