Healthy diet means something different to different people: some will say you need grains and carbs to feel in optimal health, some will say go 100% keto or full carnivore. Don’t blindly trust anyone because nutritional science is highly anecdotal and nobody really knows what we are doing here, aha.

BUT! The simple rules are: cut out sugar and processed stuff. Cook everything yourself and only eat sugar if it’s in a whole fruit package made by nature itself (like a whole apple, NOT JUICES. You need that fiber!). I encourage you to experiment with going low carb and with different amounts of protein/fat since that balance is possibly the most important. Fat will keep you full, protein will preserve your muscle, carbs should optimally be low and come only from whole fruits and vegetables, sometimes grains if you can tolerate it, but when you feel like it try cut it out to experience how your body feels.

Eggs, fatty fish (as look as you don’t over eat them since there is mercury in them - I love mackerel!), fatty meat, cruciferous vegetables will be your best friends. NUTS (almonds, hazelnuts, etc) and SEEDS are possibly the best snacks for portability and satiety feel. Beware of eating too much legumes (beans, peanuts) because they could potentially be inflammatory. Eat them, but IN MODERATION.
Use spices! Curcumin + black pepper is anti-inflammatory and well tolerated by virtually everyone. Start with that and then go a little crazy and experimental. Spiced veggies are the best! DRINK A LOT. Drink at the very least 2l of water a day.

Now for the anecdotal part: I suffered from chronic inflammation with a wide range of symptoms for more than 2 decades, I went into “detox diet” (what a silly name)where I cut out sugar, diary and gluten for 30 years. I was kind of desperate for a solution and… it worked. After two weeks it resolved my chronic skin condition (eczema/psoriasis) and when I unintentionally entered ketosis (I had no idea what I was doing at the time) my constant brain fog lifted. My arthritic symptoms completely vanished overnight. I felt like a brand new human being.

Now, after 7 months from that experiment I mostly eat what I call a “lite keto diet”, meaning: unrestricted meat/fish with fatty parts left on, a lot of vegetables and some nuts as snacks. No grains/cereals, but sometimes I will have my mother’s risotto, but only a little, because I love it but after eating it I feel sluggish so I indulge only a little bit. I eat fruits when I feel like it, which is probably around twice/thrice a week. Once a month I will eat something with flour/gluten and diary. This month will be pastries for my birthday, next month I will have pizza or lasagna. My vice is chips and sometimes I eat a bag of chips in a sitting and feel like hell. BUT EH. It happens. I also do intermitting fasting (I only eat lunch and light a snack around 5pm) because I’m not that hungry anymore and the less time I spend cooking/eating the better, lol. My energy level are quite good nowadays, but sometimes I do feel light headed if I’ve had more carbs than usual or if I’m fasting for too long because I forgot to eat my snack. I’m still experimenting AND I’m losing weight. I lost around 15kg since February with minimum effort (from 87kg to 71kg). The first 10 days of the detox diet were hell, but now I’m used to eating like this and it’s going great.

Good luck, SugarCatDestroyer! Experiment a little bit and RECORD IT. For at least one month try to keep a food diary and write down your energy levels. It will help tremendously!
