If you eat a 57 gram Snickers bar it is impossible to put on more than 57 grams of weight. I'm not really sure what you're looking for here.

Right, but a single Snickers bar would net more bodyweight than a single head of cabbage is my point, because the Snickers bar is higher in calories, which means that the starting weight of the pre-consumed food is not indicative of weight gain. So how is that weight being actualized during the digestive process?

Calories are the unit of measuring heat energy. You should actually light a peanut on fire and light a dried piece of cabbage on fire.

Which one burns hotter, brighter, longer? This is actually the test they do in the lab to figure out calories, using a device called a bomb calorimeter.

It's chemical energy just like gasoline in your car. Not all gas is the same octane.

You're forgetting that your body changes those dry sugars into fat by adding water, so if you were dehydrated, you wouldn't put on the fat either - Though you could die from dehydration, so don't do that either. Your body is basically always 55-60% water, so if you're very heavy, you're storing a lot of water as well.

You're asking why some things contain more energy (that you can extract) than others?

Time to look up the Krebs cycle and oxidative phosphorylation. I'm sure they've been explained in detail on this sub before, and good old wikipedia will probably do a decent job of it too.
