The study I posted below indicates that creatine may cause inhibition of fat loss. ..
There's not much info about diet of men who participated in the study,though.
I've seen another one performed on men who were eating a hypocaloric diet - (18 kcal) x kg(-1) ED...
In that study there was no significant difference in fat loss between the two groups, but their caloric intake was very low and the study lasted only 4 days.
I would drop the creatine. ...

The influence of creatine supplementation on substrate utilization during rest was investigated using a double-blind crossover design. Ten active men participated in 12 wk of weight training and were given creatine and placebo (20 g/day for 4 days, then 2 g/day for 17 days) in two trials separated by a 4-wk washout. Body composition, substrate utilization, and strength were assessed after weeks 2, 5, 9, and 12. Maximal isometric contraction [1 repetition maximum (RM)] leg press increased significantly (P < 0.05) after both treatments, but 1-RM bench press was increased (33 +/- 8 kg, P < 0.05) only after creatine. Total body mass increased (1.6 +/- 0.5 kg, P < 0.05) after creatine but not after placebo. Significant (P < 0.05) increases in fat-free mass were found after creatine and placebo supplementation (1.9 +/- 0.8 and 2.2 +/- 0.7 kg, respectively). Fat mass did not change significantly with creatine but decreased after the placebo trial (-2.4 +/- 0.8 kg, P < 0.05). Carbohydrate oxidation was increased by creatine (8.9 +/- 4.0%, P < 0.05), whereas there was a trend for increased respiratory exchange ratio after creatine supplementation (0.03 +/- 0.01, P = 0.07). Changes in substrate oxidation may influence the inhibition of fat mass loss associated with creatine after weight training.

thanx for the info....

I know someone uses creatine through his entire diet. He says it keeps the water in his muslces, but if your on low carbs it wont retain sub Q

i still take in 5 grams a day and havent had a problem at all. i read somewhere (sorry forgot where) that 5 grams a day burns of an extra 100 calories not sure if this is true or not. has anyone else heard of this?

Bump. I wouldn't mind hearing some more opinions on this. I like the creatine during my diet for the extra strength, but if it is slowing down fat reduction I will drop it.
