بنیادی توانائی جلائی گئی (Resting Energy)
تعریف
Estimated calories burned at rest to maintain basic physiological functions—breathing, circulation, cell production, and organ function.
یہ کیوں اہم ہے
Basal/resting energy typically accounts for 60-75% of total daily energy expenditure: - Total energy context - Understanding where calories go - Weight management - Baseline for energy balance calculations - Metabolic health - Extremely low values may indicate issues - غذائیت planning - Base for dietary recommendations
How It's Measured
Calculated from your profile data using standard equations (similar to Harris-Benedict or Mifflin-St Jeor formulas): - Age - Biological sex - Height - Weight
Important: This is a calculated estimate, not a direct measurement.
Reference Ranges
Varies significantly by body size:
| Factor | Effect on BMR |
|---|---|
| More muscle mass | Higher BMR |
| Larger body size | Higher BMR |
| Male sex | Typically higher BMR |
| Older age | Lower BMR |
Typical adult ranges: - Women: 1,200-1,600 kcal/day - Men: 1,400-1,800 kcal/day
Wide individual variation exists.
Confounders & حدود
- Estimate only - Not measured directly
- Standard formulas - May not fit all body types
- Doesn't adapt - Metabolic adaptations not captured
- Body composition - Formulas use weight, not muscle/fat ratio
استعمال کے مواقع
- Total daily energy - Basal + Active = Total expenditure
