I've also been a yo-yo dieter for years and my 'healthy diet' probably is not healthy to most people on here. But it's a long way on from where I was.
I try not to skip meals. I sometimes can't face much first thing but try to have a handful of nuts anyway.
I don't use meal replacement shakes anymore. I try and eat my calories in real food.
I drink lots of water. But also a fair bit of sugar free fizzy and don't beat myself up for that. I'm reducing it slowly, and am incorporating some green and herbal teas.
I don't eat low fat anything. I eat fat at every meal, be that avocado, nuts, seeds, nut butter, cheese, oil based dressings, sour cream, yogurt, mayonnaise, olives, the whole of the egg (not just the whites) meat without the fat removed (chicken skin, pork crackling), fatty fish, etc.
I try and eat as much veg as possible. But don't beat myself up if I eat cake, ice cream or chocolate instead. I just eat more veg at the next meal.
I exercise for my mental health and to feel strong, for flexibility and to enjoy the use of my body, not to punish it in any way. I never exercise when my body hurts. I go at my own pace.
I am working on seeing who I am not as a 'before picture' but as a person who deserves love and compassion right now, especially from myself.
I have problems with binge eating, and realising that and my emotional relationship with food and the triggers for eating certain foods and overeating have really helped me. I try and play detective now, either before a binge if I interrupt that or after, but with a curiosity not with the intent to shame myself.
I have accepted that my body has been through a lot being on a yo yo journey with me and that it's going to take time for it to recover into a more stable pattern of eating, but it it happening and although I am not losing weight I am not gaining either. I have levelled out and my natural satiety is returning, my hunger signals are sorting themselves out, I no longer have big blood sugar crashes or anything. My blood pressure has also normalised. My gut health is recovering, it was really messed up for a while there as well.
But I eat pizza and donuts and cake and sweets and ice cream and chicken nuggets and burgers and all kinds, so I'm not sure others would see it as healthy. But for me it's finally viewing food in terms of what it will do for me, not wether it is a good or bad food or 'syn'
