I actually don’t eat crisps, biscuits or chocolate myself, apart from 85% dark chocolate, usually 2 squares day, occasionally 4 squares. It didn’t used to be the case - I used to consume large quantities of all of the above, much larger than he is having.
I tried moderation, in the form a daily or weekly allowance. I tried it repeatedly for the best part of 60 years. And could never stick to it.
But complete abstinence, that I can do, and have been doing for 9 months now. It was a battle firstly to accept it was necessary, and then hard work to do it.
Complete abstinence isn’t necessary for everyone - just as some people (including me) can consume alcohol in moderation with no difficulty at all, the alcoholic can’t. I can’t consume sweets and savoury snacks in moderation, some people can.
It’s not for me to tell anyone else, including DH, that they are an addict and need to abstain, that’s a realisation for them to come to themselves. If indeed it is the case.
But the first step towards that realisation is often trying to moderate, and failing. Which means you need a target. This amount of sweets/snack food, this often, and no more than.
If he sets a sensible target, and sticks to it - hurray!! The rest of his diet is generally healthy and not excessive. I am confident he would lose weight if he stuck to a moderate intake of crisps, biscuits and chocolate. If he tries and fails, well then we have a different conversation.
But first we’ve got to have the one in which he goes beyond saying he wants to “do something” and spells out what it is he wants to do.
I am adamant that I am not going to bully or manipulate him into changes he’s not really willing to make. Quite apart from the whole personal autonomy issue, it’s pointless, because it won’t work long term.
He and I need to talk. I’m working on it.
