#21 Sí, eso lo he oído muchas veces. Y he oído gente que dice que más de 2g/kg te revienta los riñones, etc. pero ¿de dónde sacáis esa cantidad?
El caso es que The Protein Book me parece un libro bastante completo sobre todo este tema con total fundamento científico. Y la conclusión de McDonald es que el rango ideal para desarrollo muscular está en 2,4 y 3 gr/kg dependiendo de otros factores.
De hecho, te cito este extracto de un artículo suyo donde sitúa el mínimo absoluto en 1.5 g/kg para las personas obesas que no entrenan nada:
So basically we have an intake continuum ranging from about 1.5 g/kg (0.68 g/lb) as a minimum for the obese non-training individual up to a high of around 3.3 g/kg (1.5 g/lb) of protein per pound of lean body mass for very lean heavily training athletes or bodybuilders with middle ground values being found in between those two extremes. You’ll note that I didn’t put any of those values in terms of percentages for reasons discussed in Diet Percentages: Part 1 and Diet Percentages: Part 2.
So that’s what I mean by ‘adequate protein on a diet’ when I use that phrase. It’s context dependent with the primary variables being body fat percentage (as this goes up, protein requirements go down), caloric intake (as caloric intake goes down, protein requirements go up and vice versa), and activity (with regular activity generally increasing protein requirements).
