First a little background... I'm a vegetarian. Normally I'm an incredibly healthy eater. I don't eat any bad stuff at all, no junk food, no candy, chocolate, desserts, chips, fries, not even things like goldfish. I will eat Vegetables, fruits, and grains. I also eat nuts, milk products, and beans for protein. I make sure I get enough protein every day, since it's so important. Now my problem(if you can call it a problem): Occasionally(maybe once every two weeks or so) I feel(not emotionally or mentally, more like I have a deep, undeniable need) I have to eat lots and lots of FAT. Saturated fat, a large amount of calories too. I'll eat anything with lots of fat(and/or calories). For instance, I felt like this today. I ate helping of macadamias, almost a whole can of smoked almonds, a big(and I mean big; about 1/4 of the block) cube of cheese, bowl of cereal, 6 graham cracker sheets, 5 granola bars of various flavor, some pop tarts, and what was left of the can of mixed nuts in my house. I don't gorge or make myself sick on this, but at the same time I know I shouldn't be eating all that stuff in one meal period. Following the large intake of fat and protein, I get a...rush, I guess? I feel...very male, if that makes any sense. Like lots and lots of testosterone was suddenly released into my body. Within about 15 or 30 minutes after my meal, I can notice a visible increase in my muscles. Not only do they become larger, they become more defined. And I mean all muscles; even my abs push out of my stomach more than usual. Usually when this happens I work out, and when I work out I find that I can push around MUCH more weight than I normally can without tiring. This muscle surge continues for 6 hours or so. Usually this happens at night, so I go to sleep before the time is up. Then when I wake up in the morning, the largeness from last night is gone and in place of the muscle gain is just a lot of fat that I subsequently work off in the following days. After about 4 days of eating like normal and working out with my usual weights, I'm back where I was before I ate all that stuff. So that's my story. Anybody have an idea what the deal is with me?
