7 Facts You Need To Know About Causes Of Obesity
Obesity means having too much body fat which increases your risk of diabetes, heart disease, stroke, arthritis, and some cancers. It can be caused by several reasons
1. Eating too much food in general, and too much of the wrong kind in particular. There has been an increase in the consumption of sweetened drinks over the last three decades and the consumption of fast-foods has tripled over the same period.
2. With the increasing amount of electronic convenience devices, people are leading a much more sedentary lifestyle. Shopping, which used to done at the grocers, bakers, banks etc, is now done at large supermarkets, shopping malls and on-line. Most households have several televisions and computers and children spend more time in front of them.
3. If you do not sleep enough your risk of becoming obese increases. Professor Francesco Cappuccio and his team at the University of Warwick, reviewed evidence in over 28,000 children and 15,000 adults which clearly showed that sleep deprivation significantly increased obesity risk in both groups. He explained that if you do not sleep enough you produce Ghrelin, a hormone that stimulates appetite. It also results in your body producing less Leptin which suppresses appetite.
4. It is thought that too much fructose in drinks can cause lipid accumulation, fatty liver, and eventually lead to hypertension, resistance to insulin, diabetes and obesity. Researchers have compared the effects of fructose and glucose on the brain with MRI scans and found that the areas of the brain that regulate appetite become active and release hormones which tell you to stop eating when glucose is consumed but not when fructose was consumed.
5. It is thought that some medications cause weight gain. If you believe this is the case discuss an alternative medication with your doctor.
6. The longer a person is overweight, the harder it becomes for them to lose weight and obesity seems to become a self-perpetuating state. It has been found that the “normal” body weight of a person who becomes obese starts going up because the body’s’ expectation of normal weight increases, regardless of whether they go on diets. It is important therefore to take action early to try to prevent a lifetime of obesity.
7. Variants of a gene, called IRX3, have been reported to make carriers of the gene overeat. Researchers say that people who carry this gene tend to eat too much, prefer high-energy, fatty foods, and are usually obese but it is still not proven.
