Eating carbs will make you fat
First of all, putting the argument about bread and baked goods aside, I want to highlight the fact that fruits, vegetables, beans, legumes, and nuts are all rich in carbohydrates. When you say "carbs make you fat," you're making a blanket statement that's fundamentally untrue.
Second, all three macronutrients -- protein, fat, and carbs -- are important in their own ways. They have different roles in the body and provide different nutrients that can be used to create a vitamin-, mineral-, and energy-rich diet. None of them by itself will "make you fat."
What "makes you fat" (which is a horrible phrase, by the way) isn't a specific type of macronutrient; it's an out-of-whack energy balance and metabolism that combine to store excess nutrient intake as fat, regardless of what type of macronutrient you overconsume.
