Can Sudden Stop In The Intake Of Oxy Elite Pro Cause Weight Gain?

I am in my second - third week of cycling off of oxyelite pro and notice the weight loss has stopped at this week s weigh in and in fact coming back. My caloric intake, diet and exercise routines haven t changed. Started my 2nd round of P90X last week. Did my cycling off OXP elite Pro cause the weight gain and decrease in metabolism?
