How many calories do I need?
We need to have an energy balance, eating the same calories that we spend every day, so in order not to lose weight or increase is necessary to take account of the energy expended to live our body, ie sleeping, digesting food, moving blood through the arteries, breathe and think, and many more functional activities.
To find out how many calories you need, we must first perform the calculation of basal metabolism which accounts for 60-70 percent of total calories that our body spends every day and therefore should be substituted for healthy living.
There are different formulas for their calculation, including a very easy to apply is:
Men: kg body weight x 24
Women: kg body weight x 24 × 0.9
To be clear, basal energy expenditure spending must add physical activity to get an estimate of total daily calories expended, and therefore the need to consume calories to achieve energy balance.
A slightly more accurate formula for discrim age and height, to calculate the basal metabolism is:
Male: 10 x Body Weight (kg) + 6.25 x height in cm – 5 x Age + 5
Women: 10 x Body Weight (kg) + 6.25 x height in cm – 5 x Age -161
Cover the basal metabolic cost is the least we can eat each day to stay healthy, of course, and explain how to determine total energy expenditure when physical activity is considered.
