What I learnt today in class

Well today has been frightfully exciting. I have to do little tests once a week to make sure that I'm learning all of the things that I should be learning about what is going on inside my body and why it's reacting in certain ways to certain things.

So I thought I'd share all of this fascinating information with you, my loyal readers. Some of it may be completely obvious to you, but Biology was never my strong point, so bare with me and maybe we'll all learn something! I'm going to be tested on this tomorrow, so if I've got anything drastically wrong, hopefully some genius reader will spot it.

Normally, my body breaks down foods and converts carbohydrates in to brain sugar and blood sugar (also known as glucose). This provides me with the necessary energy to wobble to work and dance around with my hairbrush etc. When I eat more than necessary, the extra glucose is stored in the liver, but when the liver is full too, the excess is converted into a condensed form for storage, which is FAT.

So when losing weight, you have to use up first your energy supply, then the glucose stored in the liver, and finally you can make a dent in the fat. As the glucose stored in the liver is stored with about 4 times its weight in water, the first week of a diet involves lots of trips to the bathroom to get rid of the liver water (as the glucose stored there is being used to run the body) and that's why you lose a lot of weight in the first week!

Did I pass?!?!?

The Howard's Way formula contains about 450 calories for a girl (think boys get about 600), so by about day 3-4 all the liver glucose has been used up, and you burn the fat instead. This is why I spend my evenings peeing in bottles- because they monitor it to see if there is glycogen left, and if there isn't, it's called KETOSIS (which is a good thing).

So there you have it. I call it "Emma's Biology 101."

Speaking of which, why do people say that? 101 I mean, why does that mean a basic level of learning? Think it's an American thing, care to enlighten me?
