My bad there I was just grazing and saw that and was like Wtf. But I' m still curious about the bolded statement, As far as I know its extremely rare for protein to spill over and be stored as fat.
It's not rare...it's only rare for it to happen when you are taking in normal amounts of protein and it spills over - this is a severe medical condition.
HOWEVER - when you are taking in MORE protein than your body will USE...it has two options - 1. store it 2. spill it
An average 200 lb man who doesn't exercise only requires and metabolizes approximately 25g protein / 2 hours. That means that at the end of a 16 hour eating day, that man would have consumed 200g protein total to maintain muscle mass and amino stores.
However, when exercise (especially muscular training) is present, that protein intake requirement goes up AFTER the exercise has been performed, and the time after that.
If that same 200 lb man exercises vigorously for 2 hours, he will require 60g protein immediately after the workout to properly recover and feed the muscles. In addition, the other meals after that will require more protein as well...approximately 35-40g protein instead of 25.
So for the daily routine eating every 2-3 hours. If a 200 lb man is very active (at least 2 hours exercise per day) he will require 320g protein instead of the 200g protein baseline.
Once he starts taking in more than 320g protein, the rest of it is most likely stored as fat, or wasted (either spilled or burned directly as energy). Do not forget that protein = calories as well, and excess calories in rather than burned will equal fat stored.
320g protein = 960 cal
200g carbs = 600 cal
100g fat = 900 cal
total cal for 200 lb man on a maintenance cycle = 2,460 cal (approx 2,500 cal)
If that man wants to cut, he will remove 150-175 of those carbs, to bring himself down to approximately 2,000 cal / day - which will still maintain muscle mass, but destroy fat two-fold (with glycogen depletion and caloric deficit).
If that same 200 lb man wants to bulk, he will increase his carb intake by approximately 100-150g carbs for a total of approx 400-450 more calories than maintenance.
