Three simple calculators, three different questions
| computer | Key question |
|---|---|
| BMI calculator | How does my weight roughly compare to my height? |
| Calorie requirement calculator | Roughly how high could my daily energy needs be? |
| Calorie Deficit Calculator | What target value results from a planned deficit? |
BMI is just a rough marker
BMI can provide guidance, but it does not know body composition, training status or individual medical factors. Therefore it should always be read carefully.
Why calorie requirements are just a starting value
Formulas like Mifflin-St-Jeor are useful because they provide a systematic estimate. But you know nothing about your real everyday life in a specific week.
What a deficit can do
A computational deficit is a planning value, not an automatism. If you plan too aggressively, you will achieve mathematically lower target calories, but you will often not get a better everyday life.
Practical use
- BMI calculator for the rough classification
- Calorie requirement calculator for a daily value
- Calorie Deficit Calculator for a moderate goal
Conclusion
The calculators are helpful if they don't promise too much. This is exactly why formulas, hints and limits are visible on ultra computers.
