In some instances, obesity and genetics are closely related (but not in all of them). If you are wondering whether genetics are to blame when it comes to obesity, this information will help give you an answer.
To become obese, you may have inherited genes which makes you more susceptible for developing obesity (thanks, mom), or you may have a mutation in your obesity gene. Genetic differences between people can affect their appetite, metabolism and eating behaviors; making them more susceptible to develop obesity.
Having inherited genes from your parents may make you more likely to develop obesity, but it doesn’t mean that you will actually get the condition. Outside factors, like exercise and food intake, still determine whether you will contract obesity. If you have obesity genes, but you watch what you eat and you exercise often, the chance of becoming obese is very slim.
Obesity can be a side effect of various medical conditions and syndromes, such as Prader-Willi syndrome, Bardet-Biedl syndrome, Cohen syndrome, leptin disorder and MOMO syndrome. For that reason is it very important to consult with a doctor if you suspect that you may be obese.
Leptin disorders can make you gain significant weight by making you constantly hungry. There was a case of a young boy who had a leptin disorder. His body could not produce any leptin; which made him ravenously hungry every second of the day. At age 4, he ate 1200 calories at a single meal (about half the intake of a normal person), and weighed 90 pounds. Luckily his doctor discovered the condition and treated him with leptin injections. The injections stilled his ravenous hunger and helped maintained a normal weight.
If both of your parents are obese, it significantly increases your risk of becoming obese. Studies have shown that 80% of the offspring of two obese parents were also obese. Science also points to obesity risk being much higher for a person with a family history of obesity.
As you can see, obesity and genetics may be related. In some rare cases, your genetic susceptibility gives you little control over obesity. But in most cases, you control your fate when it comes to being obese; even though you may own obesity genes. A regular exercise program and a calorie controlled diet will limit your obesity risk.
