The document discusses calculating a person's basal metabolic rate (BMR), which is the number of calories burned at rest. It explains that the BMR decreases with age but can be increased through cardiovascular exercise. It also presents the Harris Benedict formula for determining total daily calorie needs based on BMR and exercise level, multiplying BMR by 1.2 for little exercise up to 1.9 for high amounts of exercise.

2. You use energy no matter what are you doing
and when are you sleeping.

4. The BMR will calculate your Basal
Metabolic Rate, the number of calories that
you burn if you stay all day in the bed.
If it becomes harder to eat but you want and
stay thin, you learnt that your BMR
decreases as you age. However a regular
routine of cardiovascular exercise can
increases your BMR.

5. • The BMR formula uses the variables of
height, weight, age and gender to
calculate de Basal Metabolic Rate. This is
more to calculate calories that you need
on body weight in a day.

6. • Harris Benedict formula: to determine your total
daily caloric needs.
- if you don´t do much exercise: BMR x 1,2
- if you do exercise (1-3days): BMR x 1,375
- if you do exercise (3-5 days): BMR x 1,55
- if you do much exercise (6-7 days): BMR x 1,7
- if you do a lot of exercise: BMR x 1,9

daily caloric needs.

- if you do much exercise (6-7 days): BMR x 1,7
- if you do a lot of exercise: BMR x 1,9
