Yes.
The last year I've stopped drinking alcohol, no caffeine after 12:00, and (for the last 3 months) seriously reduced my UPF (less supermarket bread, no bought cakes/biscuits/crisps) and sugar (no more sugary cappuccinos, sweet treats are rare). I've tried to eat as many whole foods as possible (fruit, veg, nuts, meat, pulses) and eat limited amounts of good quality processed foods (olive oil not seed oils, greek yoghurt instead of low fat flavoured yoghurts, honey, still eat cheese but limit it). I also only eat in a 12 hour window (I've tried harsher time restricted eating but it doesn't work for me. 12 hours is do-able and stops me snacking after dinner).
I've never been a big exerciser - walking and yoga are the only things I do and yoga is not regular, so it's my diet which has changed overwhelmingly.
I sleep better, I'm less tired (no more falling asleep on the sofa in the afternoon/evening or comatose at work), I'm less anxious. I now really notice the difference if I was to have caffeine past 12/alcohol/sugar: I'm exhausted and sleep poorly. I have been having hot flushes for the last 18 months and these have stopped with the bigger, more consistent changes in my diet 3 months ago.
I have lost weight (I need to - currently in the overweight BMI category) but my main aim has to feel better about myself.
I really like the book "The Four Pillar Plan" by Dr Rangan Chatterjee which thinks about health holistically based around Food, Movement, Relaxation and Sleep. I really like the Hairy Dieter's books for recipe ideas.
I have been a comfort eater most of my life but the realisation that the treats, whether it was a glass of sauvignon blanc, a tonic, a packet of crisps, cheese and biscuits, were only making me feel better in the short term and in the long term (and even on a daily basis) were actually making me feel worse physically and emotionally has helped me change my habits. Now my comfort eating is more about eating a delicious home-cooked meal (meatballs in red wine gravy with rice and veg; sweet and sour chicken; tagliatelle with butternut swaths, spinach and goats cheese; curries; lasagne ), stashing leftovers for lunch the next day, really enjoying a selection of different fruits/veg, nuts for a snack (instead of a sad apple that's been slowly shrivelling in the fruit bowl for weeks). I personally like eating meat and don't cut out things like pasta/rice, but just think more carefully about my portion sizes and make sure there's enough veg. I have to plan with shopping and freezer stash, but doable.
