Yes! The biggest factor with body weight is calories in vs calories out. Foods with volume and mass but fewer calories displace calorie dense foods. Even as simple as substituting popcorn vs potato chips is huge on calorie savings. Protein and fats (ideally plant based) can also help you feel full longer than say simple carbs like potato chips/white pasta.
I highly recommend Harvard’s Nutrition Source for science-based nutrition info and recipes, the language is very accessible too!
