How many calories Do you need per day?

Basal Metabolic Rate (BMR)

The BMR is the amount of energy you need to sustain your life. This includes your breathing, organs and everything else you need to keep alive:

Men: BMR = 66 + (13.7 x wt in kg) + (5 x ht in cm) - (6.8 x age in years)

Women: BMR = 655 + (9.6 x wt in kg) + (1.8 x ht in cm) - (4.7 x age in years)

Daily Calorie Requirement (DCR)

Next, we factor in how active the person is, by using the Activity Multiplier:

• Sedentary = BMR x 1.2 (little or no exercise, desk job)
• Lightly active = BMR x 1.375 (light exercise/sports 1-3 days/wk)
• Moderately active = BMR x 1.55 (moderate exercise/sports 3-5 days/wk)
• Very active = BMR x 1.725 (hard exercise/sports 6-7 days/wk)
• Extra active = BMR x 1.9 (hard daily exercise/sports & physical job or 2xday training)

Daily Calorie Requirement (DCR)

You are a 30 year old female, 30 years old, 5' 6 " tall (167.6cm) and weigh 120 lbs (54.5 kg).

• Your BMR = 655 + 523 + 302 - 141 = 1,339 calories/day

Your DCR = 1.55 x 1339 = 2,075 calories/day
