Calculate your required daily TRIM’S TRIVIA
Being overweight can
change your stature
It’s probably just common sense,
You can estimate the amount of food you need daily to stay at the same weight but researchers in Brazil (Clinical by detailed and complicated laboratory analyses, or it can be estimated through Biomechanics, July 62005) have found formulae, such as those below for males and females. that being overweight is likely to lead to stature changes that can cause a Resting Metabolic Rate (RMR):
Males: 66 + (6.22 x wt(lbs)) + (12.7x ht(inches)) - (6.8 x age) Females: 655 + (4.36 x wt(lbs)) + (4.32 x ht(inches)) - (4.7 x age) From the estimated metabolic rate, you can see that even a 50kg woman requires around 1200kcals per day to balance metabolism in the resting state. So In measuring intervertebral disc height, any diet of less than 1200kcals is likely to lead to weight loss.
Special calculations are then needed to estimate the extra requirements for carrying the load, but the obese men’s physical activity carried out throughout the day. Again, the general consensus is that for even a sedentary person, the RMR should be multiplied by about 1.2, when they weren’t carry an extra load. whereas an extremely vigorous person may require a multiplier of more.
