Errr, I think we know these 'basic' things quite fine. Energy burned needs to be >= energy taken in. It's just complicated for other reasons.
There are a lot of incentives to stay unhealthy. There're the biological incentives (eating a shitload and packing on a few pounds is good if you're in the jungle and might not eat again for a few weeks), and the incredible cultural pressures that prey on those biological incentives (taco bell spends a lot of money to encourage you to make bad health decisions).
Salt, cholesterol, fat, carbs - these are distractions from being healthy. People who eat healthy amounts of reasonable food (although even then, there's that guy who ate twinkies for a year and managed to lose weight by keeping his calories in check) rarely suffer from poor nutrition.
Yeah, everyone knows that guy who was a vegan and ran every day for 40 years and keeled over at 45 from a heart problem. He's the exception.
