15 lbs is a pretty big swing for somebody your size. It'd be more likely in a 350 lb'er.
But... it's doable with fluids. At 215 lbs, I could lose 7-8 lbs with an hour+ of cardio. Your bladder might be capable of holding a couple pounds of fluid. You sweat some at night. You can pack your stomach with several pounds of fluid. Huge changes in salt and carb consumption can affect your fluid balance within a day or so. A good dump can approach 5 lbs.
I guess if you get it all coordinated right, you can pull off a 15 lb swing. To do that regularly without really trying is weird though.
