I'm no expert...but just left a 13.1 page which was discussing the exact same thing. Reasons given for gain were water gain to keep you body cool and hydrated, increase on blood to pump through the workouts, muscle gain and simply needing more to fuel your body. Their suggestion was to kick out the scale and begin to focus on body/muscle changes which occur over time. Maybe try to look up the forum(13.1)...click to my page and then click on the team logo to follow the discussion. Don't give up....we're in this for the long haul. You are doing fantastic!!!
