In these 2 studies, 6 obese, untrained subjects and 5 highly trained bicycle racers were tested for fitness and endurance at baseline, and then given 1.2 to 1.75 g of
protein per kg of
reference weight for 4 - 6 weeks of a ketogenic diet.
The UK Government recommends a
reference nutrient intake («RNI») of 0.8 g
protein per kg of bodyweight
per day for adults with no special dietary requirements *.
