Frequently Asked Questions
What is basal metabolic rate?
Basal metabolic rate (BMR) is the energy your body needs at rest for basic functions like breathing, circulation, and cell renewal. It accounts for about 60-70% of total daily energy expenditure.
How is basal metabolic rate calculated?
The most common formula is Harris-Benedict or Mifflin-St Jeor, using weight, height, age, and gender. Mifflin-St Jeor is considered more accurate for modern populations.
What is the Basal Metabolic Rate Calculator?
The basal metabolic rate calculator computes the energy your body uses at complete rest, i.e. the minimum energy for organ functions.
How does the Basal Metabolic Rate Calculator work?
Enter sex, age, weight and height. The calculator computes the basal rate using the Mifflin-St Jeor or Harris-Benedict formula. The basal rate is the foundation for calculating total energy expenditure.
Key Data and Facts
Basal rate men: approx. 1,500-2,000 kcal/day. Women: approx. 1,200-1,600 kcal/day. The basal rate decreases with age and increases with muscle mass.
Step-by-Step Guide
How to calculate Ihren Grundumsatz step by step: 1. Geschlecht angeben: Die Formeln unterscheiden sich fuer Maenner und Frauen. 2. Alter, Gewicht (kg) und Groesse (cm) enter. 3. Formel nach Mifflin-St-Jeor: Maenner: GU = 10 x Gewicht + 6,25 x Groesse - 5 x Alter + 5. Frauen: GU = 10 x Gewicht + 6,25 x Groesse - 5 x Alter - 161. 4. Ergebnis ablesen: Der Grundumsatz gibt an, wie viele Kalorien Ihr Koerper in voelliger Ruhe verbraucht (Organfunktionen, Atmung, Koerpertemperatur). 5. Gesamtenergiebedarf calculate: Multiplizieren Sie den Grundumsatz mit dem PAL-Faktor (Physical Activity Level): sitzende Taetigkeit PAL 1,2, leichte Aktivitaet 1,4, moderat 1,6, aktiv 1,8, Leistungssport 2,0+. 6. Fuer Gewichtsverlust: Reduzieren Sie die Kalorienzufuhr um 300-500 kcal unter den Gesamtbedarf. Den Grundumsatz sollten Sie niemals unterschreiten.
Calculation Example
Frau, 35 Jahre, 65 kg, 168 cm: GU = 10 x 65 + 6,25 x 168 - 5 x 35 - 161 = 650 + 1.050 - 175 - 161 = 1.364 kcal/day. Gesamtbedarf bei PAL 1,4: 1.910 kcal.
