You have probably heard
old myth, that you should not eat before bed, because all
food you eat will be stored as fat. That is simply not true. People burn quite a number of calories while sleeping or resting in bed. If you know how many calories you are going to burn while sleeping, you can eat
same number of calories without getting fatter. For bodybuilders and athletes, it is important to eat before bed. Doing so will bathe
muscles with complete amino acids for
whole night. I am going to develop a mathematical formula, so that you will know how many calories you can eat before bed, without getting fatter.
First, we need to calculate your Resting Metabolic Rate(RMR). There are many formulas, and for
sake of simplicity, let's use Owen's equation.
Owen's equation(kilograms):
RMR (male) = 879 + (10.2 * (body weight in kilograms))
RMR (female) = 795 + (7.18 * (body weight in kilograms))
Owen's equation(pounds):
RMR (male) = 879 + (4.64 * (body weight in pounds))
RMR (female) = 795 + (3.26 * (body weight in pounds))
One day has 1440 minutes. If we divide RMR by 1440, we will calculate how many calories per minute does a person burn at rest. Now, that we know this number, it is time to calculate how many calories a person will burn while sleeping. Sleeping has a MET value of 0.9, which means a calorie burn rate of 0.9 * (RMR/1440) calories per minute.
Finally we have to multiply
calorie burn rate per minute by
number of minutes that a person sleeps. We arrive at
formula: 0.9 * (RMR/1440) * number of minutes sleeping
