Alba Diaz posted a video saying she put on six kilos over the summer and finds it hard to walk into a gym. "My head spins when I have to go to the gym," she says. This is not a statement from someone who happened to walk past a camera - she is the daughter of designer Vicky Martin Berrocal and bullfighter Manuel Diaz, and has lived her whole life in front of a lens.

The sentence that says the most is not the one about the kilos. It is this one: "They will see that I have put on six kilos, that they will be watching me." So the fear is not of the mirror, but of the audience. That is the point where influencer work stops being work and becomes a contract in which the body is the product and the comments under a post are a quarterly report.

What she describes about the summer will sound familiar to anyone who ever came back from a holiday feeling they had left something unfinished. "We enjoyed ourselves a lot, we want to be more present. I was very happy with my friends and family, and at the same time it gave me anxiety." Happiness and anxiety in the same sentence, with no contradiction. Which of us does not know that one?

The industry that pays Alba Diaz is the same one that manufactures the fear she is now defending herself against. First it sells you an image of a body, then it sells you a fitness subscription to reach it, and finally it sells you self-acceptance content for when you give up. Three products, one customer, the same till.

Her conclusion is sharper than everything before it: "The only person you owe an explanation to is yourself." That is easy to write in a caption and hard to live by when your income depends on how many people are watching. Whether she really believes it will show in what she posts in three months.

Still, it counts for something that someone on that side of the screen says it out loud. Balkan social media runs on an economy identical to Spain's - only the budgets are smaller, and the pressure is the same. Six kilos are not news. That six kilos are enough to become news, that is the news.
