🎯 Accuracy Tips
For the most accurate results, measure your weight at the same time each day, preferably in the morning after using the bathroom and before eating.
📏 Body Composition
Including body fat percentage significantly improves accuracy. Consider getting a DEXA scan or using bioelectrical impedance for better measurements.
⏰ Gradual Changes
Aim for gradual weight changes of 1-2 pounds per week. Rapid weight loss can lead to muscle loss and metabolic slowdown.
🔄 Regular Updates
Recalculate your calorie needs every 2-4 weeks or after losing/gaining 5+ pounds, as your metabolism adapts to changes.
