Gonzalo Quesada, FitGeneration and the lettuce club

Gonzalo Quesada, FitGeneration and the lettuce club

Gonzalo Quesada is not a doctor, dietitian, or biologist. He is a data analyst, as he admits in his own interviews: he started a Mathematics degree but never finished it. From this profile, he leads the nutrition department of FitGeneration, an academy that offers courses promoting veganism as the ideal diet and personal training with university recognition, which reportedly accumulates nearly 700,000 monthly visits. His channel, focused on reading studies, has become one of the most cited voices in official food discourse. And that is where the problem begins.

What is FitGeneration and who is behind it

The structure is typical: a popularizer without formal education in the field selling science with an independent aesthetic. Quesada appears as the pedagogical director of FitGeneration's nutrition area, a platform that processes its vocational training (FP) courses through an accredited center, not with its own degrees. The packaged message is recognizable: meat is bad, saturated fats are bad, anything not from the garden is suspicious.

In the same ecosystem are other names. The channel Impacientes, with doctors Víctor and Delia, and Dr. Miguel López Moreno repeat the same script with different voices. The coincidence of message, format, and conclusions has led many to speak of a coordinated campaign. There is no documentary proof of this in available material, but the suspicion of commercial interest behind it—courses, brands, funding—hangs over the entire matter.

The contradictions attributed to him

The most repeated criticism is not ideological, but methodological. Quesada bases his conclusions on observational studies, and some argue that this type of evidence is insufficient to dictate dietary guidelines. Against this, others maintain that solid evidence on protein quality points in another direction: the FAO's DIAAS system, from 2013, places eggs, milk, and meat near 100% digestibility, while most plant sources remain far below.

The other major accusation is selective bias. The Ancel Keys case is cited as precedent: he obtained data from 23 countries and published only the 7 that supported his view. Later reviews of those same seven found that the variable most correlated with heart attacks was not cholesterol, but sugar. The trap, they say, has been repeating itself for sixty years.

The business of the plant-based diet

The economic background is the argument with the most weight in the criticism. Some claim that the food, pharmaceutical, and other industries employ teams of data analysts to steer study design toward desired results. According to circulating calculations, 95% of studies are funded by commercial companies, and the choice of analysis method conditions the conclusion. Therefore, a data analyst is not a neutral referee: they are just another piece of the chain.

The result, according to this reading, is a discourse sold as rebellion with evidence but which reproduces the official narrative. The paradox is that this narrative changes every decade: eggs were demonized and then recommended. Now it is animal protein's turn.

Physical appearance as an argument

There is a less rigorous but very present chapter: the physical appearance of the popularizers. They are described as excessively thin, with dull skin, dark circles, and low energy. The argument is that if they trinc the optimal diet, they would look better. This is a subjective assessment, not data, and should be read as such. But it works as emotional reinforcement for the rest of the criticism.

What can be concluded

The issue has two layers. One is the legitimate discussion on nutrition, where evidence is not closed and selection bias in studies is a real problem. The other is the suspicion of a business built on that discussion, with courses, brands, and opaque funding. That Quesada lacks a university degree in the subject does not automatically invalidate his analyses, but it does force us to ask why he is presented as an authority.

The prediction, with reservations: as carnivore and keto diets continue to gain ground, more officialist voices with an independent aesthetic will appear. The business of selling premium smoke at master's degree prices is not going to disappear on its own.
