The Weight-Calorie Connection
Maintaining a Healthy Weight
Calories are units used to measure:
• Energy in food.
• Energy your body uses for life processes and physical
activities.
Maintaining a healthy weight is a matter of energy balance. The
calories you consume must equal the calories your body burns.

Calculate Your Needs
•
Women:
65 + (4.3 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years)
•
Men:
66 + (6.3 x weight in pounds) + (12.9 x height in inches) - (6.8 x age in years)
• Mr. Peifer
•
66+(6.3x205)+12.9 x 70) – (6.8 x 23)= 2259.22 Calories
