1.6 Grams of Protein a Day Per Kilogram of Weight

To answer the simplest question of whether taking in more protein during weight training led to larger increases in muscle size and strength, the researchers added all of the results together. [...] But those who did ramp up their protein gained an extra 10 percent or so in strength and about 25 percent in muscle mass compared to the control groups. The researchers also looked for the sweet spot for protein intake, which turned out to be about 1.6 grams of protein per kilogram of body weig...

The material factors which ultimately limit the expansion of a technically advanced species are the supply of matter and the supply of energy. At present the material resources being exploited by the human species are roughly limited to the biosphere of the earth, a mass of the order of 5 X 10^19 grams. Our present energy supply may be generously estimated at 10^20 ergs per second. The quantities of matter and energy which might conceivably become accessible to us within the solar system are ...
