No, this is backed by the laws of thermodynamics, properties such as homeostasis, and the path of least resistance.  An example being, human brains take large amounts of energy.  Humans supposedly only use a fraction of their brains.  Since you didn't evolve to require eating 100 McDonald's burgers per day to power the full extent of your brain, you're kind of inherently lazy by default.  Dolphins supposedly even shut parts of their brains off while still roaming around.  

If you did evolve to use 100% of your brain and bodily systems at all times, and the required, intensive metabolic activity to support it, the wear and tear on organs and buildup of external carcinogens from processing all that would probably kill the host pretty fast before being able to participate in K selection strategy, so you'd require R selection strategy and devolve to a rat.  That is, unless you can genetically engineer humans with the same types of anti-carcinogen attributes as things like sharks, or pseudo-biological immortality like jellyfish, plus a post scarcity ecosystem/economy on top of that...
