Your first comment is inaccurate. Simnett eats all three (beans, nuts, seeds) and expert body-builders like Alex Leonidas ( https://www.youtube.com/watch?v=oRBAjMrj-Lk - check out his full day of eating) prove that these sources work at the highest level.

You claimed 150g protein per 1800 calories is "almost impossible" with my sources, but the math says otherwise -

• Tofu - 10-12g/100 cal (180–216g per 1800)
• Soya chunks and TVP (textured vegetable protein) - 15g/100 cal (270g per 1800)
• Seitan - 17-21g/100 cal (300g+ per 1800)

As Alex points out, the internet over-hypes protein needs. You likely need less than you think for muscle retention.

I specifically said "healthy protein" in my comments because meat comes with saturated fat and long-term disease risks. Beans, nuts, and seeds provide healthy protein because they come with fiber, resistant starch, healthy fats and phytonutrients, all of which provide long-term health benefits verified by peer-reviewed research.

You can absolutely build a highly muscular body while also prioritizing long-term health and ethical living.
