Why do some people seem to gain weight easily while others stay slim no matter what they eat? It may seem unfair, but genetics play a major role in many aspects of our health.
Take a look at your parents, siblings, and extended family members. More often than not, you will notice more similarities than differences in your height, body composition, and even appearance. Genetics even influence the medical conditions we develop which, unlike appearances, cannot easily be changed with a bit of makeup.
Genetics are determined by our DNA, which come from our parents. Our genes encode every detail of our bodies and can serve as a predictor for diseases such as hypertension, diabetes, Alzheimer dementia, and even obesity.
If genetics determine our appearance and health risks, does that mean we are stuck with the cards we are dealt? Not necessarily. While genetics can provide a roadmap to our bodies, our choices navigate the journey.
There is not enough evidence to show that there is a single gene responsible for obesity. However, there are genes that make people more likely to overeat, store fat, and develop insulin resistance, all of which can contribute to unwanted weight gain. You may need to work harder to overcome these obstacles but it is not impossible with help from your doctor.
Being obese puts you at risk of developing other diseases and vice versa. Preexisting conditions that can increase the risk of obesity include:
