It's not that Wang Fan is being lazy and doesn't want to do more; it's mainly because snacks are oily and rich in flavor, and eating too much might indeed affect their performance.
So although the coaches didn't ban the athletes from eating them, they did tell Wang Fan to limit their portions.
Moreover, the coaches secretly approached Wang Fan, afraid that the athletes would find out about their sneaky actions.
There's nothing they can do; some of these athletes are stubborn, especially when it comes to defying the coaches.
So Wang Fan had to take the blame for limiting the portions himself.
Fortunately, some team members who love to defy the coaches are very polite to Wang Fan.
Qin Haiyang is 19 this year, and although he's young, it's already his second time competing in the Olympics. Four years ago, at the age of 15, he already won an Olympic silver medal.
He also has a fun nickname—"Rice Eater Bro."
