Basal Metabolic Rate (BMR) is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions.

What BMR measures:

• Breathing
• Circulation
• Cell production
• Nutrient processing
• Protein synthesis
• Ion transport

Activity Levels:

• Sedentary: Little or no exercise, desk job
• Light Exercise: Sports 1-3 days/week
• Moderate Exercise: Sports 3-5 days/week
