My wife started secretly eating. She wasn't doing what I'd consider hoarding food, but the Little Debbie's and cupcakes were disappearing from the pantry at an alarming rate and I hardly ever saw her eating them. She would wait until I wasn't home and no one else was around and pig out on stuff. She was hitting the chips and donuts pretty hard at work, too. She's 5' 4" tall and gradually put on about 60 lbs.
About 3 years ago she was promoted from a pretty sedentary position at work to a job that required a lot of running around and some lifting. She started losing some of that weight. When she noticed it she started changing her diet, going from donuts, cupcakes and chips to fruit and yogurt for snacks. She stopped buying the Little Debbie's and junk food at home, too.
She slowly shed most of that weight over time, but kept wearing the same clothes. I only recently (a year ago) noticed she had lost all of that weight. She's looking amazing again, and I'd barely noticed it. I sure notice it now.
Part of the reason was that she was embarrassed so she wouldn't let me see her without clothes on, and the clothes she was wearing were the same baggy clothes she wore when she was heavier and they weren't very flattering. She stopped going swimming at her parent's place, too, which used to be an almost weekly thing in the summertime. Not to mention I was a shitty husband and wasn't paying attention like I should have. She's turned into an exhibitionist with me. She runs around naked more often than clothed when we're home alone now.
The thing that bothered me was the fact that she hid her eating. I thought that was kind of weird. She also had, let's say, a complicated relationship with truth and transparency in general.
She's done a pretty complete overhaul on that since d day. She's been very transparent and truthful with me for the last year now and I believe there aren't anymore secrets. It's kinda like she's now addicted to radical honesty and tells me everything. I think she gets her dopamine hits from demonstrating honesty and transparency now, and I'm pretty tickled about it. I can see it in her face when she opens up and talks to me about stuff now. I've been reacting very positively to it.
I don't know what to make of the strange eating habits, but that's done now. She's on a health kick and wants to lose another 10 or 15 lbs and she's putting the effort into it. Hey, I'm all for it. I've been super supportive and cook healthy meals for both of us.
