  • Obesity is a multi-factorial illness,

  • what this means is that there are several causes of obesity.

  • Let's first talk about genetics, there is a genetic component to being obese.

  • Unfortunately, there's nothing we can do about that though.

  • The good news is that there are other causes of obesity which we can control.

  • One of them might be other health conditions.

  • For example, if you have an underactive thyroid that's not properly treated, you can gain weight

  • and eventually become obese.

  • Other medications may also lead to obesity.

  • These can be medications such as insulin, steroids, and even some antidepressants.

  • Most of the time however, obesity is not caused by a medical illness that you have.

  • Obesity occurs when you have excess fat storage.

  • When you eat food, it's digested and then the nutrients are absorbed into your bloodstream.

  • You burn calories throughout the day,

  • the excess calories that you don't burn eventually become stored as fat.

  • So if you're eating more than you're burning off, you're going to become obese.

  • A sedentary lifestyle can also lead to obesity.

  • If you have a job where you're sitting at a desk for most of the day

  • and you don't really get up and walk around, that can also cause obesity

  • because you're not burning those calories that you're eating throughout the day.

  • So you want to make sure that you eat and you make good choices with your foods and

  • also that you try to maintain some level of activity in your life.

  • So those are some of the causes that can contribute to obesity.
