• Water. No drinks other than water or black coffee/ tea.
• Understanding nutritional value better and counting calories (for a while). Intuitive eating has been sven better for me after that.
• OMAD. One meal a day. Suited my hunger pattern for a long time and allowed me to feel full after a meal which I like while feeling light most of the day which I also like.
• Home cooked meals 99% of the time. Literally. Maybe eat out once a month most months.
• Enjoying feeling healthy, so liking eating the things I ate and working out etc.

Things I didnt need but do recommend:

• Improved fiber intake.
• Cutting all caloric drinks.
• Know how much fat youre adding to your food, that tsp you just added are actually 2 tbsps.
• Choose better carbs. Thats mostly about fiber content again. So whole wheat instead of white.
• Dont mean to sound like that guy but good for gut foods. Yogurt, pickles and other fermented products.
• The mental side. Know that a bad meal, day, week doesnt ruin anything. You don't need to be perfect, just improve in the long term.

I could go on forever but I'll stop here.
