Not likely, but...: Sounds like you need to re-learn signals your body uses to indicate after-meal fullness.However, there are lots of other causes of excessive weight gain (in your case almost a pound ; a half a week)--perhaps metabolic (thyroid, adrenal), fluid-retentive, emotional binging, even pregnancy ; more. Start with the pregnancy test, then if negative go see your doctor to address other causes.
