Im a couple of years older OP and feel much the same way. I read up and look into all sorts of healthy ways to eat, buy all the cookbooks, even signed up for Zoe last year, yet still cannot get my head into the right zone to eat less. I think I've almost overloaded my brain on diets and have lost the way.
To start 2025 I'm going to attempt to break it into basic simple and small steps.
Accountability - This above all else. Monitor what I actually eat. I'm thinking either Slimming World or MFP. Not sure which yet, have lost weight with both historically. I like the idea of getting weighed weekly in a class. Part of this for me will be cutting back on meat and experimenting with alternatives to pasta/rice. Although not cutting out any food group entirely, massively reducing sugar intake.
Move - everyday. I'm not going to put pressure on myself to do so many classes a week or go to the gym. Simply getting out of the habit of sitting and reading/netflix. Even if it's just a brisk walk. I need to change the habit I have embraced of sitting so much.
Sleep - another habit I need to change is staying up so late, usually around 12pm, so getting to sleep around 1pm. I don't start work until lunchtime so not getting up early, but I'm always groggy on a morning and want to start maximising the time I have first thing to be more active.
I drink loads of water already and go to Pilates once a week. My focus is going to be logging my food to start. I usually try and do everything at once, eat better, join a gym, time restricted eating, getting 10K steps in....then give up. I'm starting with one main goal and will add to it as I get better at it.
