There are multiple studies--some on humans and some on rats--to show biochemical effects of capsaicin on fat reduction within the body.
At any rate, all that aside, I think I'm really just addicted due to my tendency to take things to extremes. It's gotten to the point now where I'm disappointed if I have to eat a meal without some kind of spicy ingredient. I carry a shaker of black pepper and a bottle of hot sauce with me at all times. When I plan my meals and snacks, in my mind I'm trying to choose foods that go with the hot sauce I have, rather than the other way around. It's become a lifestyle for me.
I don't know how long it will last, but it's fun. I found that after less than a week of adding hot sauce to every meal I had worked up a tremendous tolerance for spices. I didn't even have to force myself to suffer extremely spicy dishes to get used to it--I just had to gradually let it build up in my system. Whereas before I could barely tolerate a tablespoon-sized dash of chili sauce in on a plate full of chicken yakisoba I could now drink that same sauce straight if I wanted to after less than three weeks. It really takes no special effort to reach that level.
However, having the tolerance I do, it's still fun to push it to extremes once in a while as a test. I buy all the spiciest sauces and seasonings I can find and add them all to the same dish sometimes. For example, I might get a cheeseburger or slice of pizza and add cayenne, black pepper, and Frank's Red Hot Xtra Hot all at the same time. This rates as "pretty spicy". If I add more my food drips. I need spicier sauces.
I did have a bit of an interesting experience a couple times though by mixing activities. I was deliberately over-spicing my food one night to the point where it was really quite agonising, but I continued anyway. My face sweating, my mouth watering to cope with the irritation, and finally I started to feel a slight bit light headed. I assume this was the point at which endorphins were starting to kick in, because at that point I didn't really notice the pain as much, and I was able to keep eating. Well, to make things interesting, I figured I'd take a couple gulps of brandy that happened to be within reach. The burn was a bit different, but what made it really interesting was when the alcohol started absorbing into my body.
I assume the mixture of dopamine from my brain due to the pain and alcohol hitting my system while I was in that state of vascular stimulation and raised body temperature was what caused the sensation that followed. For the ten minutes that proceeded, I felt quite euphoric. I became giddy and laughed out loud, eventually falling to the floor where I giggled and flailed my arms joyously, thoroughly reveling in the natural sensation of being overwhelmed with a mellow sense of well being.
Well, it sounds a bit embarrassing to explain it that way but hey, it was fun and presumably safe, and nobody was around to witness it, so I feel it was a noteworthy experiment with good results. :-) I was able to reproduce these results once after but failed on a third attempt. I think the failure was due to an attempt to rush through it. (I actually know very little about neurochemistry, so please feel free to offer a better explanation of what happened here if you know how to word it.)
In conclusion, good times.
