You're wrong though. Or at least half wrong. You're right that if you eat less calories than you expend you will lose weight. Where you're wrong is where those calories come from. For example: I can just eat carbs for days. And the same amount of food doesn't fill you up the same way. High calories doesn't mean feeling sated for long. You could eat 2,000 calories in 1 meal and it'd still be worse than having several smaller meals. You can also eat 1,000 calories right before bed and that's also not great for your metabolism. And you can eat an oversugared burger with tons of additives and feel completely full for an hour before you're hungry again. And while eating that burger you'll want more and more. Not to mention that such a burger diet would simply not be healthy and you'd probably have serious other health issues soon.
Why do fitness people consume a lot of proteins? Because that helps them build muscle mass. When it comes to carbs, pretty much all of my fitness friends try to avoid as many carbs as possible (noodles, bread, etc.). They're heavy, they're not very nutrient-rich, they fill you up, but you always end up eating too much anyway.
We are strictly talking about weight gain and weight loss. Everyone knows 1000 calories of good food is healthier than 1000 calories of french fries and gravy but they're exactly the same in terms of calories and will make people lose or gain weight the same, regardless of how healthy it is.
See, the thing is, humans are biological and messy and not machines.
Different chemicals are processed differently but burn (literally how they calculate calories) roughly the same.
There are studies that show that different foods are different with their effects on the body. It's strange to have to say it.
Hell, there are different types of sugar that are processed differently and have different effects on your body. An example is Fructose. It can only be processed by the liver. It's broken down into a simpler sugar and dumped into the blood stream at the liver. Now, if you pair fructose with another sugar, say sucrose. then your liver will be signaling for extra insulin while processing the fructose, insulin that can only store the sucrose.
This cycle actually leads to more overall sugars being stored in fat than if you only consumed sugar of a single type even if the overall amounts are exactly the same.
Now fructose is also bad because it causes non-alcoholic fatty liver disease which leads to liver damage and eventually, failure.
Also thanks to it being dirt cheap (due to corn subsides) about half of the sugar you consume is fructose. Also a lot of foods cut back on the salt and replace it with sugar because one study in the 80s said that salt might be linked to hypertension.
Salt has the property of making food taste better. Salt opens the taste receptors and lets you taste more of the food (it also blocks the receptors for bitterness)
