According to Bilsborough and Mann in 2006, protein intake is mainly restricted by the urea cycle, but deriving more than 35% of energy needs from protein leads to health problems. They suggested an upper limit of 25% or 2-2.5 g/kg, "corresponding to 176 g protein per day for an 80 kg individual", but stated that humans can theoretically use much larger amounts than this for energy. For arctic hunter-gatherers, the amount can seasonally increase to 45%.
