I am in a similar position and need to do things slowly to improve my appearance and well being. I had braces and composites and also sadly I am having one implant ( poor 1970s dentistry).
My current step is to swap breakfast croissant for Greek yoghurt, seeds, walnuts, blueberries and kefir etc. I’m actually lov8gnthst and it keeps me going easily to lunch.
I have also completely given up alcohol.
My next step is to swap couscous for quinoa and try to have that as my ‘carb’ a few times per week. I already have an evening meals of lots of beans, tofu, vegetables etc.
So the next step thereafter is to work on lunch and take out the sandwich and crisps and swap it to healthier cottage cheese/ chickpea/ avocado combination
Once I have embedded that as a routine I will try to fast for 16 hours once per week and then extend that.
I need to work on my exercise regime as going swimming twice or three times per week is simply not enough. I have bought 2 kg weights and leave those downstairs and do them whenever I go downstairs. I download videos of TikTok. I will use the trainer at the gym to sort out a programme for em that I feel comfortable with. As part of that I will buy new gym clothes so I feel more confident.
if I feel th need to self destruct I will try to take myself out for a walk and get in some steps.
My plan to tackle my dismal appearance is to take one step at a time, embed it and not be too harsh on myself. I don’t check my weight or look in the mirror to often as aging gets me down. As my appearance improves I will reward myself with a few new clothes to make it feel worthwhile.
At the end of the day, I largely have my health and that is the main thing.
