Before You Begin

Just as everything has a start, we’ll begin with the basics.

Losing weight is a process that has shown significance in the most recent decades. Thanks to ease of living and not watching what we eat, most of the times, we find ourselves battling the bulge. It takes sincere and honest effort to lose weight. But, with the help of Quick Weight Loss Tips!, you can accelerate the amount of weight lost.

Before you can determine how to lose weight, you must know if it is healthy/necessary for you to lose weight to begin with. You can know the answer to that by checking your Body Mass Index, commonly referred to as BMI.

Based on the your input of weight and height, the BMI is calculated. The following is how it’s done:

BMI =Weight [in kilograms] / (Height [in meters])²
or

BMI =Weight [in pounds] x 704.5  / (Height [in inches]) ²

Next you need to know what the BMI value  represents. This number can help you determine if you are underweight, normal, overweight or obese.
