Obesity has become a major health problem today. However, it cannot be explained by genetics alone. Factors in our environment also play a significant role in weight gain. While research shows that some people are genetically more prone to gaining weight, it also reveals that chemicals in the environment and processed foods can trick our bodies and lead to weight gain.
Obesity And Genetics
Scientists have proven that genetic factors influence weight gain. According to a study conducted at Boston University:
Those who are genetically prone to gaining weight begin experiencing weight gain from the age of 4, and this difference grows as they get older.
Exercise can balance genetic effects. People who are genetically prone to gaining weight need to take 10,000 more steps per day compared to others in order to maintain their weight.
Thanks to genetic tests, not only a person’s tendency to gain weight but also their predisposition to diabetes and heart disease can be identified.
Although genetic factors are important, adopting a healthy lifestyle can help prevent obesity. Therefore, individuals who are prone to gaining weight need more support.

Environmental Factors That Lead To Obesity
Another study conducted at Boston University revealed that certain chemicals in our environment (obesogens) can trick our bodies by increasing hunger and promoting fat storage.
According to Dr. Barbara E. Corkey’s research:
Some additives in processed foods mislead the pancreas, causing unnecessary insulin release and fat storage.
Environmental factors such as pesticides, plastics, and air pollution disrupt metabolism and lead to weight gain.
These chemicals that create oxidative stress in the body send false hunger signals, creating an unnecessary urge to eat.
Identifying and eliminating these chemicals could be a major step in the fight against obesity.
Solution Suggestions
Genetic Tests And Personalized Health Programs
By learning our weight gain risk through genetic testing, personalized nutrition and exercise plans can be created.
Including genetic tests in healthcare systems may be beneficial for early diagnosis and preventive measures.
Avoiding Harmful Chemicals
Stricter monitoring of food additives and pesticides may reduce the use of harmful chemicals.
Reducing plastic consumption and combating air pollution can lessen the negative effects of environmental factors.
Adopting A Healthy Lifestyle
Exercising regularly can prevent weight gain despite genetic factors.
By avoiding ultra-processed foods and eating a natural, balanced diet, the risk of obesity can be reduced.
Conclusion
It is not accurate to view obesity only as a genetic inheritance. Environmental factors also greatly affect weight gain. Harmful chemicals can trick our bodies, leading to unnecessary hunger and fat storage. However, by adopting a healthy lifestyle, it is possible to minimize these effects.
In the future, with the widespread use of genetic tests and stronger environmental regulations, it will become easier to prevent obesity by developing personalized health solutions. The fight against obesity should be carried out not only through individual efforts but also through a broader strategy that addresses genetic and environmental factors together.
