4 Common Factors Contributing to Weight Gain and Obesity

The Centers for Disease Control and Prevention (CDC) states that obesity is a common, severe, and costly disease. Meanwhile, the World Health Organization (WHO) backs the statement by mentioning that the worldwide count for obesity has tripled since 1975.

However, even if medical experts linked obesity to over 60 chronic diseases, it is preventable through proper diet, exercise, and lifestyle changes. But it is also worth taking note of the common factors that contribute to why people gain weight, maintain it, and develop into obesity.

1. Genetics

Genetics contribute to most aspects of the body, not just looks, and personality, but also health, including weight control. According to the National Institute of Health (NIH), genetics account for some weight gain or loss.

As you may have known, some people can eat anything they want and stay slim all their lives while others seem to gain weight anytime they eat a slice of chocolate cake. Whether you have a chubby or skinny family history, you should know the signs to watch out for if you are genetically predisposed to obesity.

For example, if siblings and parents have obesity, the NIH indicates that there is a higher possibility for you to develop weight problems, too. In addition, the genetic link is thought to be more robust when both parents are obese than when only one of them is.

2. Food Choices

While genetics may play a role in preventing weight gain, you can control what you eat. Even if your family history is prone to obesity, you do not have to become another family tree member.

You can learn to choose foods that will help you lose weight. But make sure to stay away from processed food because it may cause weight gain and make you put on more pounds over time. You can check out the information below, including some tips on choosing the suitable types of food.

3. Insulin Levels in the Body

The number one cause of obesity is insulin resistance. Insulin is a hormone released by the pancreas to help the body use glucose or blood sugar. However, as the body becomes resistant to insulin, the insulin level increases in the body, and the resistance becomes worse. It means that the body needs more insulin to use the same amount of glucose.

The insulin-glucose resistance syndrome is linked to obesity because the body uses more insulin than usual. As a result, the pancreas may not keep up with the supply. It can become a vicious cycle and cause weight gain, even if you do not have a family history of obesity.

The NIH recommends exercising and losing weight to cut back on insulin resistance. You can lower the insulin level by improving your diet and adopting a healthier lifestyle.

4. Age

As you age, your metabolism slows down. It means that your body is not able to burn as much fat. So, you may not lose weight as quickly as when you are younger. You may find it hard to lose weight by adjusting your diet or exercising. You may want to consider weight loss surgery.


If you have a family history of obesity, you may want to watch out for these symptoms. Monitoring your weight can help you stay healthy and prevent you from becoming obese.
