The coach won't invent the science. Every calorie and nutrient it quotes comes from a named, published database — and every exercise burn from the standard scientific reference. Here is each source, its licence, and the credit it asks for.

Some dishes (like feijoada or bibimbap) aren't measured in any database. Rather than guess, the coach computes them from their real ingredients — each drawn from the sources above — and always shows you the ingredient breakdown and labels the result an estimate, never a measured value. Calorie burn is likewise shown as a range with a ±20% band, because individual energy expenditure genuinely varies that much.
