Caloric intake - Caloric expenditure = Fat Gain or Fat Loss or No Change
BMI = Body Mass Index or Body Mass Indicator. BMI is an international measurement of obesity.
BMI = weight (pounds) / [height (inches)]2 x 703
Example: weight = 155 pounds, height = 5 foot 8 inches (68 inches)
BMI example calculation: 155 ÷ (68 x 68) x 703 = 23.6
BMI = weight (kilograms) / [height (meters)]2
Example: weight = 70 kilograms, height = 1.73 meters
BMI example calculation: 70 ÷ (1.73 x 1.73) = 23.4
Standard weight status from the Centers for Disease Control and Prevention is meant for adults. Highly trained athletes with more muscular builds may be classed as overweight by the BMI but are not overfat.
Below BMI 18.5 = Underweight
18.5 to 24.9 = Normal
25.0 to 29.9 = Overweight
30.0 and above = Obese
BMR or Basal Metabolic Rate is your body’s Caloric expenditure when resting. Meaning, it’s the Calories burned when you’re doing nothing. Your bodily organs, such as your liver, brain, heart, kidneys, muscles, and other organs burn lots of calories.
Using the Miffen - St Jeor formula:
Your estimated BMR = (10xWeight in kg + 6.25xHeight in cm - 5xAge in yrs) +5 for males and -161 for females
Muscles burn more Calories than fat. So your weight may affect the calculated BMR. It will be difficult to know exactly what your BMR is.
Note: The BMR calculation looks like a small number relative to your consumption. So, it’s important to move you body and burn more Calories!
