HOW TO DETERMINE EXCESS WEIGHT

 

 

To determine your weight level, you need to know your BMI, which is the body mass index.

 

BMI 30 or more is obesity.

 

 

BMI 25 to 30 is defined as pre-obesity.

 

 

25 or more is described as overweight or obese.

 

 

There are several ways to measure a person's fat level or the level of adiposity based on weight and other bodily observatory functions.

 

DUAL-ENERGY X-RAY ABSORPTIOMETRY (DEXA)

 

 

DEXA was first invented to measure bone density, but the imaging function of this x-ray can determine the content of fat in the human body. This method involves using the different mass of body fat, tissues and also identifying which part of the body contains more fat and the ones with a minimum amount of fats. It is one of the modern tests for fat considered accurate and perfect since the actual amount of fat will be sighted through the imaging found through x-ray. DEXA requires much medical equipment which tends to be expensive, and also professionals are needed to operate the machine for accurate results.

 

HYDROSTATIC WEIGHING

The second method for determining body fat is the hydrostatic weighing, and it involves dipping the body into the water completely. In the submersion, a material is provided which will function in determining the body weight of the individual in the water. The submerged weight is compared with the dry weight to determine the actual and definite overall body density of the individual. The muscle and fat level is also considered, through which the estimate of the body fat is made. This assessment tends to be close to perfect in most circumstances. Also, the hydrostatic weighing requires trained professionals to administer for proper result.

 

BIOELECTRICAL IMPEDANCE ANALYSIS

 

 

Using this method, the body's electrical resistance is measured using an electric current passed through the body. It is important to know that muscle and fat conduct electricity differently, so it is easier to determine the body fat percentage content. Unlike the above methods of determining fat, this process requires little to no training and could be used at home by amateurs to assess their body fat percentage. However, factors such as body temperature and hydration can affect the body mass index. So, care might need to be taken while performing this experiment.

 

SKIN FOLDS CALIPERS OR PINCH TEST

 

 

This method consists of pinching the skin on some point on the body and

measuring the thickness of the field obtained. This pattern of measurement is focused on the amount of fat directly under the skin. So, after the analysis, the actual body weight can be determined without further test or measurement. The measure is also aimed at determining the surface fat distribution of the body. Even though fats not directly deposited under the skin may not be measured, a further calculation will still establish a close estimate of the amount of body fat available.

 

SIMPLE WEIGHING

 

 

In this case, your weight will be measured with a simple weighing scale and computed with the optimal required weight to determine whether your weight is optimal or not. Although this method is the least accurate, it is almost the most widely used throughout the world. For precise measurement in determining overweight or obesity, factors such as muscle mass, body type and height must be put into consideration. For a start, you could use the scale, but if you doubt the result, you may need to apply more advanced methods.

 

BODY VOLUME INDEX

 

 

This technique is the use of 3D software to determine the actual image of a person. It functions and gives results based on BVI rating, in which the differences in individual's body mass index are put into consideration. This method  overcomes  the  obstacle  of  shape  and  other  different  functions  or

features of the body that is particular to individuals. The software measure mainly where fats are located and do not have to calculate the total weight. The abdomen is not the only position weight is determined, so the BVI system considered more body parts.
