She said she mostly survived on a few pieces of pasta because it was "impossible" to eat the rest, "but today I ate all the fat they serve instead of meat because I was very hungry." She added she lost a lot of weight and "my bones are already sticking out".
The quarantine hotels are increasingly the target of criticism from athletes and their teams, who are lobbying organisers for improvements. There's a lack of transparency, too: only some virus-positive athletes are forced into quarantine hotels where their teams don't have access, while teammates in similar situations are allowed to isolate within the Olympic village.
The rules for athletes who test positive say those without symptoms go to a dedicated hotel for isolation. Anyone who has Covid-19 with symptoms will go to a hospital. In both cases, they'll be unable to compete until cleared for discharge.
Teams have started going public with criticism.
After Eric Frenzel, a three-time gold medalist in Nordic combined, tested positive, German delegation head Dirk Schimmelpfennig lambasted the "unreasonable" living conditions. Germany wants larger, more hygienic rooms, and more regular food deliveries so athletes who are eventually released are still fit to compete, Schimmelpfennig said in comments reported by the FAZ newspaper.
The pressure can pay off. Belgian skeleton racer Kim Meylemans was brought back from a quarantine hotel to isolation in the athletes' village after she made a tearful post on social media. Her main gripe was the lack of information. She was loaded into an ambulance and transported from one quarantine facility to another on a day she thought she was being released.
Vasnetsova passed her time in quarantine with a little detective work. When fetching the food left outside her door, she took a glance at the boxes left outside other rooms in her corridor, whose doors were labelled with signs to distinguish Olympians from other people working at the Games who tested positive, such as team staff.
She concluded the athletes were getting worse food, and underlined it with a picture of food served to her team doctor, who had also tested positive and was living two floors below. He had fresh fruit, a salad and prawns with broccoli.
"I honestly don't understand, why is there this attitude to us, the athletes?!" she wrote.
Two days on from her criticism, Vasnetsova is still in quarantine but things are looking up.
Russian biathlon team spokesperson Sergei Averyanov posted a picture of what he said was an improved meal delivered to Vasnetsova's room including salmon, cucumbers, sausages and yogurt. A stationary bike will be delivered soon, he added.
Vasnetsova, he wrote, "is already smiling, and that's the main thing".
