How does healthy weight loss work?
If you want to lose weight healthily, the first step should be to deal with your calorie requirements and your diet. It often quickly becomes apparent that more calories are consumed than consumed every day. As a result, we gain fat and weight. In order to lose weight, however, we need to expend more calories than we take in. But how does that work?
In order to break down a kilo of fat, a total of around 7000 kcal must be saved. That’s quite a lot when you consider that the average daily human requirement is 2000 kcal. So one thing in advance: losing weight is a marathon, not a sprint!
Calculate calorie needs
There are numerous calorie calculators on the Internet, but they all give different results. To arrive at a value, calculate your requirements with several calculators and take the average of the results. It is important that you calculate your basal metabolic rate and your total turnover . If you want to save calories, you should always subtract the deficit from the total turnover! Another method to calculate consumption is the Harris-Benedict formula.
What is the basal metabolic rate?
The basal metabolic rate describes the calorie consumption that the body uses in complete rest. This includes all bodily functions such as heartbeat and breathing.
What is the total sales?
The total turnover consists of the basal turnover and the performance turnover. All physical activities such as sports, going for walks, tidying up, shopping or tapping your feet count towards performance turnover.
Women : Basal Metabolic Rate= 655.1 + (9.6 x weight in kg) + (1.8 x height in cm) – (4.7 x age)
Men : Basal Metabolic Rate = 66.47 + (13.7 x weight in kg) + (5 x height in cm) – (6.8 x age)
The result is the basal metabolic rate. To calculate the metabolic rate, multiply the basal metabolic rate by the PAL value (physical activity level) from the table:
Physical activity | PAL value |
Sleep | 0,95 |
sitting, lying | 1,2 |
Seated activity, eg office work | 1,4 – 1,5 |
Walking and standing activity eg assembly line workers | 1,6 – 1,7 |
Predominantly walking or standing activity, e.g. salesperson | 1,8 – 1,9 |
Physically demanding job | 2,0 – 2,4 |
