Answer:
I would say it shouldn't be considered THE reason since there's other things that can cause it
Explanation:
I think there are way more reasons than simply not being able to control yourself. For example, some people can't afford healthy food, some food might simply contain too much calories even if it comes in small portions, lack of exercise can cause obesity, genetics can also play an important role in obesity meaning that genes might increase a person's likelihood of gaining weight, health conditions can also cause it, and lastly, there are other factors such as stress and lack of sleep. I hope this helps.
