Formula and Logic
This tool uses the Mifflin-St Jeor equation to estimate Basal Metabolic Rate (BMR), which is the calories your body needs at rest. Maintenance calories are calculated by multiplying BMR by an activity factor. The daily deficit is a percentage of maintenance calories, and the target intake is maintenance minus the deficit. Protein intake is suggested based on body weight.
Practical Notes
- Individual variation: Metabolism can differ due to genetics, muscle mass, and health conditions.
- Consult a doctor: Always speak with a healthcare provider before starting a new diet or exercise plan, especially if you have medical conditions.
- Training periodization: Adjust deficits during intense training phases to support performance and recovery.
- Dietary guidelines: Follow balanced nutrition principles; deficits should not lead to nutrient deficiencies.
