In 2005, Harry Lemmens came up with a different formula that sought to address flaws that characterized previous indices. In the formula, Lemmens introduces new factors to make ideal body weight more realistic and within the acceptable levels.

### Required equipment

Because you only measure height, the equipment required is only a stadiometer.

### Procedure for calculating ideal body weight

To calculate the ideal body weight using Lemmens formula, you have to get the right body height and apply the formula.

The formula does not have variations for both men and women.

For example, what is the ideal body weight of a man with a height of 1.83 meters?

Note that [I kilogram = 2.20462 pounds], 1 meter = 3.28084 feet

### The targeted population

The Lemmens formula is applicable for the general population. While some medical practitioners still prefer using the old methods that only used height, the Lemmens appears to have gotten a breakthrough to a solution for all.

### The pros of the Lemmens formula

- The formula is relatively easy to use because everything has been worked out. You only substitute the value for height in meters.
- It can be applied fast even in strenuous situations when correct ideal body weight is required.

### Cons of the Lemmens formula

- While Lemmens indicate that the formula caters for other factors in the formula, they are still unclear.
- The greatest factor in determining the ideal body weight using the formula is still height which has resulted to major flaws in other formulae.

### Other comments

The Lemmens formula presents a new way to look at ideal body weight because of major inefficiencies depicted by other formulae. However, Lemmens fails to demonstrate how other factors included in his formula work to generate results.
