In a study by Lemon et. al., they found that 1.8g/kg of bodyweight was required for positive nitrogen balance. However, Forslund et. al. found that if you jumped up the number to 2.5g/kg, you not only had a positive protein balance but you had a negative
fat balance (you burned more
fat as an
energy source).
For those of you that don't know...divide your weight by 2.2, this gives you your kg in weight.
