Total energy expenditure |
This is a very precise metabolic calculator. It calculates your resting metabolic rate and your total energy consumption in calories or kilojoules. This can be a helpful tool for weight loss as it allows you to estimate the amount of calories that represents your energy balance. If you eat less than this, you will lose weight. |
Instructions:
1. Use the dials until you have entered time spend on sleeping and other activities on a typical day (24 hours).
2. The calculator assumes that all unaccounted time is spend sitting.

Ponderal index |
The ponderal index is somewhat comparable to Body mass index, but gives a more fair comparison between individuals of different stature.
Instructions:
1. Measure weight and height and enter values. |
Weight loss calculator |
The weight loss calculator allows you to estimate your weekly and monthly weight loss. Just enter your daily energy expenditure and the caloric content of your diet.
Instructions:
1. Enter your daily energy expenditure. You can use this calculatorto get the value. 2. Set the "Daily intake" dial at the value you plan to aim for in your diet. 3. If the evaluation says you weight loss will be "High" or "Extreme" you should reconsider your plan.
Background:
Short term weight loss is primarily determined by the difference between caloric intake and caloric expenditure. As one lb of human body fat has a caloric content of approx. 3.400 kcal the average weight loss in fat can be reasonably estimated.
This calculation is however based on certain assumptions. First of all one assumption is that all your weight loss is fat. In the beginning of a diet most people will typically also lose body water and the weight loss will therefore initially be higher.
If the daily caloric deficit is too high (i.e. >1.000 kcal/ day), most people will typically also lose muscle mass. In short term this will increase the weight loss, but in the long run this will be an unwise strategy as your resting metabolic rate and your physical capacity goes down, which will make it more difficult to maintain the weight loss.
For a healthy weight loss, you should generally aim for a daily caloric deficit between 300 and 1.000 kcal. Some of this deficit should ideally come from an increase in physical activity.
