Overweight and Obesity

---

Obesity is a medical condition that happens when a person carries excess weight or body fat that have serious health problems.  A person has obesity if they have a high body mass index.

Body mass index (BMI) is a tool that doctors use to determinate if a person is at an appropriate weight for their age, sex, and height. The measurement is a Index between height and weight.

A BMI between 25 and 29.9 indicates that a person is carrying excess weight. A BMI of 30 says that the person has obesity. more than 40 is super-obesity (It may don't apply for bodybuilders)

Other factors, such as the ratio of waist-to-hip size (WHR), waist-to-height ratio (WtHR), and the amount and distribution of fat on the body also play a role in determining how healthy a person's weight and body shape are.

If a person does have obesity and excess weight, this can increase their risk of developing a number of health conditions, including metabolic syndrome, arthritis, and some types of cancer.

Metabolic syndrome involves a collection of issues, such as high blood pressure, type 2 diabetes, and cardiovascular disease.

Maintaining a healthy weight or losing through diet and exercise is one way to prevent or reduce obesity. In some cases, a person may need surgery.

Now read on to find out why obesity happens.

• Consuming too many calories
• Leading a sedentary lifestyle
• Not sleeping enough
• Endocrine disruptors
• Medications and weight gain 

(someantipsychotics, especially olanzapine, quetiapine, and risperidone

anticonvulsants and mood stabilizers, and specifically gabapentin

hypoglycemic medications, such as tolbutamide

glucocorticoids used to treat rheumatoid arthritis

some antidepressants)

• Obesity gene
• is obesity self-perpetuating?:

The longer a person is overweight, the harder it may be for the person to lose weight.

some scientist studies suggested that the more fat a person carries, the less likely the body is to burn fat, because of a protein, or gene, known as sLR11.

It seems that the more fat a person has, the more sLR11 their body will produce. The protein blocks the body's ability to burn fat, making it harder to shed the extra weight.

Take away

Many factors play a role in the development of obesity. Genetic traits can increase the risk in some people.

A healthful diet that contains plenty of fresh food, together with regular exercise, will reduce the risk of obesity in most people.

However, those that have a genetic predisposition may find it harder to maintain a healthy weight.
