The Cost of Muscle Loss: €15 Daily Steaks or Cheaper Alternatives?
For an 85 kg man aiming to maintain muscle mass, recommended protein intake is around 120 grams daily, based on guidelines of 1.5 g/kg. The most direct source is meat: with an average of 20 g of protein per 100 g, 400 g of steak would be needed daily. At €30/kg, that’s €12 just for meat, plus €3-5 for eggs and dairy. However, whether this figure is realistic or necessary has sparked intense debate.
The Reality Check: What Does Protein Really Cost?
The original calculation rests on a debatable premise. A requirement of 1.5 g/kg is an upper limit; many experts set the minimum at 0.8 g/kg for sedentary individuals and 1.2 g/kg for active ones. Moreover, protein doesn’t have to come solely from meat. Eggs offer about 6 g each, sheep’s milk provides 55 g per liter (at €2.65), and legumes combined with cereals deliver complete protein. Offal, such as beef liver (€11/kg) or sweetbreads (€4/kg), offers high-quality protein at lower prices. Even chicken, with about 23 g of protein per 100 g, is cheaper than veal steak.
Quality Wars: Animal vs. Plant Protein
One sector argues animal protein is irreplaceable due to its complete amino acid profile and bioavailability. Others contend that combining plant sources (textured soy, lentils, quinoa) achieves similar results at lower cost. ChatGPT analyses cited in the debate indicate textured soy has comparable protein quality to meat, though with lower digestibility. Consensus suggests both are valid, but choice depends on budget and preferences.
Verdict on the €15 Figure
With proper planning, daily protein needs can be met for under €10 using a mix of eggs, dairy, offal, and legumes. Spending €15 daily on steaks is an option, not a necessity. The real question is whether declining purchasing power is pushing people toward suboptimal diets, as suggested by initial observations of obesity and "muscle wasting."
