It is not medical advice. Extended fasting is not right for everyone, especially if you are pregnant, breastfeeding, under 18, underweight, or have a medical condition such as diabetes or a history of eating disorders. Talk to your doctor before you start. Weight and body composition projections are estimates, not predictions.
