ObesityKills

Waist/Height Ratio (WHtR) is a far more accurate way of measuring healthy weight than the traditional Body Mass Index (BMI). BMI is calculated as a person's weight in kilograms divided by the square of their height in meters, but a study found that the simpler measurement of waistline against height produced a more accurate prediction of lifespan.

The summary of the study is discussed in these major news websites:

This app gives the years of life lost due to obesity for non smokers. The exact research study from which the data is derived from can be accessed at the following website:

The three main features of the app are:
1>After inputting the waist, height, age and gender, loss of life-span due to obesity is calculated for people who are not smokers.
2>An option is given to install the calculated result as a short cut to your main screen, which can be then used for motivation.
3>Information and links to useful resources regarding weight loss.

This app does not store, collect or transmit any of the information entered. This free app(no ads) is only for purposes of education, information and motivation. For example, a non-smoking male aged 30 with a waist-to-height ratio of 0.8 stands to lose 20.2 years of life due to their size. When a person discovers the years lost because of obesity, this information provides an immense added
motivation to lose weight.
