Your comment is incorrect in many different ways.
Butter is fat and some sugar and protein.
No. The butter in my fridge has almost no sugar (0.6g in 100g) and almost no protein (0.7 g in 100g).
Pasta is mostly carbs.
For comparison: The pasta I have at home have more sugar (most have roughly 3g in 100g) and way more protein (12g in 100g).
they all become calories, and if you eat more calories than you burn, they will be stored as fat.
Are you sure you’re not simplifying too much?
Also, “just” eating less or more calories is not that easy if you ignore the side-effects. Carbohydrates will make you hungry very soon unless mixed (or eaten after) fibers, fat and protein. Which you should do anyways for health reasons.
How about non-native English speakers trying to shame English instead? https://www.youtube.com/watch?v=zJ69ny57pR0
