I think this is a very debatable opinion, many would say since your doing a post insulin spike anyway it would be useful especially with insulin. not to mention, as long as your not doing a show, and you quit creatine about 2 weeks out, creatine wouldnt affect your fat loss.
The original studies looking showing that exercise increases creatine loading used a aerobic exercise model ("cardio").
Taking creatine after exercise will increase creatine uptake, helping to rehydrate and even further hydrate the muscle cells.
Carbs + creatine is not as good as carbs alone for replenishing the glycogen you've used during cardio. Carbs will also potentiate the creatine uptake.
There is a study showing that creatine supplementation alone (no exercise training) can increase metabolic rate when not dieting, but another study showed that creatine supplementation alone inhibits fat loss resulting from a resistance training protocol. Diet was not controlled in either study, but if you diet and create a caloric deficit, you will lose fat.
95-99% of the creatine in your body is stored within skeletal muscle cells. Creatine does make you "hold water," but the water is held within the muscle fibers, not in the interstitial spaces like under the skin, when you take it in reasonable doses. But, if you were to take in a shitload of creatine after you were already loaded, the creatine would be absorbed but not taken up into the muscle cells, so you could hold water.
I take creatine right up until the day before a show: keep the creatine and creatine phosphate levels high and give any creatine that might draw water under the skin a few hours to be pissed out (a 5g dose is in and out of the system in roughly 5 hours).
