Health science and nutrition evolves on a constant basis, with latest studies often contradicted by earlier reports. It can be difficult to know what to believe. Although, some of latest independent studies on obesity and weight loss appear to come to a similar conclusion – and that’s the relationship between health risks and excess body fat.

It’s been agreed on that being overweight by a consider margin puts an individual at greater risks of major health problems. Such potential health risks include High Blood Pressure, Diabetes, Heart Condition, Liver Damage, Colon Cancer, and Gallstones.

There isn't such a thing as a ideal, static weight for each individual. Although various factors can be taken into account to predict a healthy range. Body Mass Index (BMI) is one measurement often used. This can be calculated by dividing weight (kg) by height (m) squared.

Here's a general classification table: Under 18.5 [Underweight] - Between 18.5 and 24.99 [Normal Weight] - Between 25 and 29.99 [Overweight] - Between 30 and 34.99 [Class 1 Obese] - Between 35 and 39.99 [Class 2 Obese] - 40 and above [Extreme Obesity]

For an individual at the higher regions of the BMI scale, there's sufficient evidence to indicate greater health risks.

An example, in the case of abdominal obesity (fat deposits around the abdomen and stomach) its related to a higher risk of insulin resistance syndrome and cardiovascular disease. In a women, a waist measurement of 36 inches or over (42 plus in men) is a strong indicator for this type of obesity. Related factors of this condition include high cholesterol, high triglycerides, and high blood pressure.

A rapid weight gain, in the region of 10 to 20lbs for a typical individual, can heighten the chances of developing diabetes (Type 2). Genetic reasons are often fundamental, although weight will also play a role, as indicated in numerous research papers.

Liver disease, except were its been associated to alcohol abuse, can be as a result of insulin resistance. This resistance is more likely to be seen in those individuals that are obese. A high BMI reading often indicates a higher change of live damage at some stage.

If obese, gallstones are more likely to develop, and might be linked to a rapid increase in BMI. Sleep disorders, such as sleep apnea is a condition that's said to be correlated with obesity.

Having a weight issue isn't just related to acceptable appearance, buts can also leads to substantial health risks.
