Excess body fat: Do I have it?
Determining if one is overweight is not easy. Health experts use various ratios to determine if one is overweight. Most popular ratio used for this purpose is BMI or Body Mass Index.
Here is how it is calculated.
Multiply your bodyweight in Pounds with 705 and then divide the number with square of your height in inches. The resultant number is your Body Mass Index.
If your BMI is with 20 to 25 then you are having normal weight. You do not need to worry about losing weight. Less than 20 will mean you are underweight and should try to gain weight. More than 25 but less than 30 will mean you are somewhat over weight but BMI over 30 will mean you are obese and need to put sincere effort to lose weight.

So if you not satisfied your BMI number you should take help of professionals to determine if you have excess fat in your body.
