I only eat lunch and dinner, and my meals are small af. I can't eat much at once thanks to my anorexic past so I eat more stuff inbetween (doesn't have to be unhealthy: an egg, some fruit, little cup of soup but also not so healthy stuff such as chocolate, variation is key)
Weekends are a mess tho... I wake up late with 0 apetite so I skip lunch completely or eat soup or yoghurt around 2 PM
I used to be sooo obsessed with diets, meal plans, calorie intake... If anything I learned, it's to eat when you want, how much you want, whatever tf you want! Just listen to your body! It's okay to eat a bit more if you're still hungry, it's okay to not finish a meal or skip one if you aren't hungry at all, but listen genuinly to your body
