BMI (Body Mass Index) is the best way of calculating your extra kilos and setting your ideal weight goal.

BMI is the ratio between your height and weight which is calculated as follows : your weight in kilos is divided by the square root of your height in meters, BMI = KG / M^2. Work out your BMI :

1 Step 1
HeightYour height in cm
WeightYour weight in kilos

Based on your height and weight, here is your BMI :

[ field4 / ((field3/100) * (field3/100)) ]


An acceptable BMI is somewhere between 18.5 and 25. A woman would ideally aim for a BMI of around 18.5, a man one of around 25, the difference being due to muscle weight, which is generally higher in men.

Below are different interpretations of BMI established by the World Health Organisation :

less than 16,5 Malnourished or Anorexic
16,5 to 18,5 Thin
18,5 to 25 Normal
25 to 30 Overweight
30 to 35 Moderately Obese
35 to 40 Severely Obese
more than 40 Morbidly Obese

The Nifty Plate calculates your portion sizes in order to help you reach a BMI of 20 for a woman and 24 for a man. Calculate your ideal weight :

According to the data entered, your weight objective is as follows :

[ field3 * ((field4/100) * (field4/100)) ] kg


Having said that, BMI is just an indication, and there are many reasons why you might want to stop losing weight before getting to your ideal BMI. These could be because you have a lot of muscle weight or are pregnant, or perhaps, by choice, because you think losing too much weight could be ageing.
