To determine the body's energy needs, you need more than just a calorie table. Because energy demand is understood to be the combination of basal metabolic rate and output metabolic rate. Both depend on various factors.

The daily energy requirement of a body depends on various factors. The daily output metabolism is added to the basal metabolic rate, which you would also need if you overslept all day. In short, the service turnover is understood to mean all that has been consumed energy of the day.

What is meant by the basal metabolic rate

  • The basal metabolic rate is different for every person. In general, it is understood as the amount of energy that you or your body need in complete rest in order to maintain all vital body functions.
  • The basal metabolic rate is not only different in men and women. Factors such as the ratio of muscle mass to fat percentage also influence it, since muscles consume significantly more energy.
  • Of course, your physical requirements such as age, height and weight also play a major role. In women, the hormonal balance is also often an issue.
  • If you struggle with a fever or are exposed to special climatic conditions, your basal metabolic rate increases as well. You can roughly calculate your basal metabolic rate (in kilocalories) using the formula body weight in kilograms times 24.

The performance turnover as an additional factor

  • Your performance is the energy that you consume through your activities within 24 hours. The work turnover is also widely spoken of.
  • To calculate the power turnover, one uses the PAL factorwhich is different for each activity. If you usually sit all day, you have a different performance expenditure than if you do gardening all day.
  • In addition to the work you do, climatic factors also play a role here. Window cleaning is significantly more labor-intensive and sweaty at an outside temperature of 35 degrees Celsius than at 15 degrees Celsius.
  • In women, pregnancy and breastfeeding also play a role. Breastfeeding up to the fourth month of life consumes an additional 635 kilocalories per day on average.

If you take into account all the factors that are part of the basic and power turnover, then you can calculate your entire energy requirement per day.
