Calories are a measurement of energy, right? So how come people that eat a lot of calories feel more lethargic?
Surely, if they are consuming large quantities of "energy", they should be really energetic. And I'm not talking about really fat people, because they couldn't be energetic if they tried.

I'm afraid our bodies arn't as simple is that. Everyone's body's different thats why some people can eat loads and stay really thin and others can't.

Yes, calories are a energy measurement, but that does not mean you use all the energy you intake!
Digesting food is a complicated process. Not all food is the same; some have more carbohydrates, protein, glucose, fat, etc. etc. So they are absorbed by the body (metabolism) in a different manner. The time, effort, chemical combinations, body functions, etc. at work vary from one food and its constituents to other.
Eating a lot or calories may mean that you have to digest a lot, and that compromises blood flow, heart rate, the body energy use for the process, the rate of absorption of what you have eaten, etc.
Picture a snake like an Anaconda. Can you see her very active after swallowing a middle size pig? For sure she is full of calories, but she is not just able to use them for her benefit. Most of them will become fat and be stored to face future needs. Something similar happens with people. Calories are either burned or store as fat.
Eating calories is not having them for immediate use and without a compromise.
