Don’t eat shit food for a meal, and snacking is usually a bad idea.
Though it’s counter to American practices, eat a large breakfast and lunch, and lighter dinner. You’re active in the day, that’s when you need food. Sleep on an emptyish stomach.
Processed foods are not good for you. “chips” are not food as in a meal.
Foods should be mostly recognizable growing things or made from them.
Fats are good for you sugar is fine – in reasonable quantities. You need fat! You probably don’t need sugar, lol, but it is tasty. But it’s a shit food source.
