My daughter is a sleep eater. Get out of bed, walk to the refrigerator, eat something, go back to bead. No kidding, asleep all the time. verified with doctors and observation. really weird. Like sleep walking, but eating. and yes, she is overweight. But weight gain is math. If he dropped to 1200 calories a day he would lose weight. he’s doing 4-5000. Its math. and massive water retention, which probably means salt or heart.
I know someone like that. She was gaining weight while her daughter was losing weight - same diet, same walks everyday to hold each other accountable. It just didn’t make sense.
She finally confessed to having chocolate in her nightstand drawer. Lots of chocolate, and constantly replenished.
