Shit genetics. People like to think every human is the same, as if they came off an apple assembly line and the only thing that isn't the same is our conscious minds. They are not, we are all genetically different.
Some people are wired to become addicted to things far easier than others and find it much harder (some impossible) to break from it. Food is an addiction.
If you can lose weight easily, it's not purely because you're some kind of chad but instead because your brain is genetically different and you are not so predisposed to addictive behaviors or have less receptors to the chemicals your brains gives off that cause you to become addicted or crave things.
