#1 "could potentially increase" - not does increase or will increase, maybe coulda sometimes increase.
#2 - "could also potentially" - same as above, but even funnier really. If you think just for a moment. accepted amount of max fat loss in a week is say 2lbs for a 200lber. thats 7000 calories worth (this is all ballpark) in 7 days, or 1000 calories worth a day of FFA mobilization. you get maybe 50 calories per hour of FFA mobilization.... so sure, do enough cardio to just burn 50 calories in an hour and even if you double it, 100 calories in an hour. still meaningless. Do an hour worth of even steady state low intensity and at least 200 calories come from elsewhere.
#3 "could lead to" and "this might be true". But doesn't state how. even if you double the fatty acid mobilization (as above) its not enough to make a dent.
then look at the flipside. If you can perform better, faster, longer doing fed cardio and your total calories for the day is the same, guess in which scenario you'll lose more fat?
