There are lots of reasons. I don’t have an eating disorder but I have suffered with disordered eating all my life and I have to say, I’m struggling.
I don’t think it has anything to do with supermarkets condoning off sections. I think those issues were small, local misunderstandings weren’t they?
Control is the main thing. As a nation, we collectively lost control of our lives at very short notice. Food and exercise are the only things we really can control anymore.
For me, a big thing is that when I’m at home, which I am most of the time now as I’ve been stuck WFH for a year, I can see my reflection everywhere! In the mirror in the bedroom or bathrooms, in the patio doors, even in the bloody oven. And every time I see it, I take a minute to criticise myself. Sometimes I get a compulsion to stop what I’m doing and go and have a look at myself. Not in a vain way, quite the opposite. In the office, I might see myself in the mirror in the toilets at lunch time and that’s it.
Also for me, it’s a huge fear of being released from lockdown and everyone looking at me and thinking “God, she’s put on weight!”
The focus on getting your daily exercise is triggering for some people. I’m super competitive so I want to go further and do more than everyone else and than I did the day before, plus everyone’s posting their times on Strava etc for all to see.
There’s also the chance to be secretive. Family May notice what you’re eating (or not) but others won’t and plenty of parents and spouses are working harder than ever so may not notice. If you have a 15 year old daughter, say, and you’re an NHS nurse, who has been there to make sure she eats lunch during homeschooling? That’s not a criticism of the parents in anyway, it’s just circumstance. Also, the popularity of lounge wear allows you to hide your body, whether it’s getting bigger or smaller. Anorexic people will often wear baggy clothes to hide how small they are getting rather than flaunt their figure.
Of course, there are other eating disorders than anorexia and it’s not hard to see how binge eating disorder or bulimia is happening during lockdown.
