Healthy Weight

What is Devine BMI formula?

Females: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet.

Males: IBW = 50 kg + 2.3 kg for each inch over 5 feet.

Robinson

Men: Ideal Body Weight (kg) = 52 kg + 1.9 kg per inch over 5 feet.

Calorie Break-Even  

Break-even calories (BEC) are the number of calories an individual can intake daily without losing or gaining weight. While the FDA points to a general 2,000 calories a day, it can actually vary between 1,300 to 3,500. Having an accurate measure is important for your ideal and healthy weight.

Calorie Break-Even = BMR x Activity Level Coefficient

Activity Level Coefficient

• Not really active = 1.2 

  • Very light activity, almost sedentary and performing only minor activities with a little walking

• Moderately active = 1.375

  • Light activity, including office work and some walking, light exercise 1 to 3 days per week

• Active + some exercise = 1.55

  • Moderate activity, including exercises and sports for 1 to 2 hours per session, 3 to 5 session per week

• Very active + daily exercise = 1.725

  • Heavy activity, including heavy manual labor or intensive sports for 2 to 4 hours per session, every day per week

BMR calculations

Imperial

• Harris-Benedict equation (1919):

  • Males: BMR = 66 + 6.23 x weight (lbs) + 12.7 x height (in) – 6.8 x age

  • Females: BMR = 655 + 4.35 x weight (lbs) + 4.7 x height (in) – 4.7 x age

• Mifflin-St. Jeor equation (prefered):

  • Males: BMR = 4.54 × weight (lbs) + 15.88 × height (in) – 5 × age + 5

  • Females: BMR = 4.54 × weight (lbs) + 15.88 × height (in) – 5 × age – 161

Metric

• Harris-Benedict equation (1919):

  • Males: BMR = 66 + (13.7 x weight (lbs)) + (5 x height (cm)) – (6.8 x age)

  • Females: BMR = 655 + (9.6 x weight (kg)) + (1.8 x height (cm)) – (4.7 x age)

• Mifflin-St. Jeor equation (prefered):

  • Males: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) + 5

  • Females: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) – 161

Calories into fat

9 calories = 1 gr of fat

9,000 calories = 1 kg of fat

255.15 calories (28.3495 gr X 9 calories) = 1 oz of fat

4,082 calories (453.592 gr X 9 calories) = 1 pound of fat

BMR

• M: = (66 + (6.23 x weight) + (12.7 x height) – (6.8 x age));

• F:  = (655 + (4.35 x weight) + (4.7 x height) – (4.7 x age));

——————

All BMR calculations should be multiplied by Activity Level Coefficient, which is defined as:

• BEC is calculated based on lean body weight (LBW) and basal metabolic rate (BMR).

• LBW is the body weight without fat (total body weight (TBW) minus fat weight).

LBW calculations

Metric calculations

• Boer Formula (Boer 1984):

  • Males: LBW (kg) = 0.407 x TBW (kg) + 26.7 x Ht (m) – 19.2

  • Females: LBW (kg) = 0.252 x TBW (kg) + 47.3 x Ht (m) – 48.3

• James Formula (James 1976, Absalom 2009):

  • Males: LBW (kg) = 1.1 x TBW (kg) – 128 x (TBW (kg) / 100 x Ht (m))2

  • Females: LBW (kg) = 1.07 x TBW (kg) – 148 x (TBW (kg)/ 100 x Ht (m))2

• Hume Formula (Hume 1966):

  • Males: LBW (kg) = 0.3281 x TBW (kg) + 33.929 x Ht (m) – 29.5336

  • Females: LBW (kg) = 0.29569 x TBW (kg) + 41.813 x Ht (m) – 43.2933

• Peters Formula for children < 15 years-old (Peters 2011):

  • LBM (kg) = 0.0817 x TBW (kg)0.6469 x Ht (cm)0.7236

• In adults, Boer and James formulas yield more reliable results and are more frequently used.

Imperial calculations

• Boer Formula (Boer 1984):

  • Males: LBW (lbs) = 0.4079 x TBW (lbs) + 1.495 x Ht (in) – 42.3288

  • Females: LBW (lbs) = 0.2513 x TBW (lbs) + 2.6487 x Ht (in) – 106.4833

• James Formula (James 1976, Absalom 2009):

  • Males: LBW (lbs) = 1.1 x TBW (lbs) – 8.9758 x (TBW (lbs) / Ht (in))2

  • Females: LBW (lbs) = 1.0692 x TBW (lbs) – 10.4054 x (TBW (lbs) / Ht (in))2

BEC calculations

• BEC = (21.6 x LBW (kg) + 370) x Activity Level Coefficient

• BEC = (9.78 x LBW (lbs) + 370) x Activity Level Coefficient

  • Activity level coefficient is measured as:

    • 1.2 to 1.3: Very light activity, almost sedentary and performing only minor activities with a little walking.

    • 1.375 to 1.55: Light activity, including office work and some walking, light exercise 1 to 3 days per week.

    • 1.55 to 1.65: Moderate activity, including exercises and sports for 1 to 2 hours per session, 3 to 5 session per week.

    • 1.725 to 1.8: Heavy activity, including heavy manual labor or intensive sports for 2 to 4 hours per session, every day per week.

    • 1.9 to 2: Very heavy, including > 8 hours of moderate and heavy activity and 2 to 4 hours of intensive daily training.
