This is the first time this has happened to me. Day before I was 63.1KG I've been steadily gaining about .7 to 1KG a week
Ate regularly as usually, Having roughly 2900-3200 calories.
Had about 3-4 main meals that night, a lot of protein and carbs. Had a couple of drinks at midnight going out (I'm not much of a drinker unless its social)
Come back home, crash on the couch for an hour, then I go and have a 1000 calorie shake before bed.
Wake 9 hours later, and I am 61.7KG? I'm really confused. I am definitely sure my body couldn't lose that much just in one night, I've been over 62KG as of last week.
Could this be water weight? I can't really tell.
