Metabolic rate | BMR | RMR
What is BMR and RMR? For it we first have to understand the Metabolic rate.
Metabolic rate:
So, not moving around or being active.
- 1) BMR: basal metabolic rate:
- 2) RMR: resting metabolic rate:
RMR is taken under fewer restrictions and has been shown to be statistically more accurate
let’s look at a couple of examples,
Here we have A (Male) and B (Female) and their metrics are shown here,
A (Male) = 44 years old, 5 foot 8 inches, and weighs 160 pounds.
The RMR equation,
Males = (4.55 x Weight in pounds) + (15.88 x Height in inches) – (5 x Age) + 5
Females = (4.55 x Weight in pounds) + (15.88 x Height in inches) – (5 x Age) – 161
when we plug in A and B’s numbers,
A= [ (4.55 x 160) + (15.88 x 68) – (5 x 44) +5 = 1592.84 Calories/Day ]
B= [ (4.55 x 126) + (15.88 x 64) – (5 x 33) – 161 = 1263.62 Calories/Day ]
We see that A’s RMR is 1592.84 calories per day.
And B’s is 1263.62 calories per day.
So after rounding up this tells us that,
It’s based on each of their lifestyles.
1.200 – Sedentary Lifestyle (Little to no Exercise) |
1.375 – Lightly Active (Light Exercise 1-3 Days/Week) |
1.550 – Moderately Active (Moderate Exercise 3-5 Days/Week) |
1.725 – Very Active (Hard Exercise 6-7 Days/Week) |
1.900 – Extra Active (Very Active Very Hard Exercise/Physical Job) |
Now, Samantha’s in the very active category so,
“A” can consume 1912 per day to maintain his current weight.
Drawbacks:
However, Jack has much more muscle mass than Kyle.
