I think there are two reasons for this.
I feel that I am like this because of my genes. My mothers family was a little on the heavy side, but my father was not, which is a relief.
Then the way I do nothing on the computer all day and eat and eat and eat. I am not watching how much calories I am taking. I used to think that if its not junk food, then its okay. Well, that is partely true, anything from white bread to cheetos could have high amounts of transfat, suger, and calories.
There are 3,200 calories in a pound. That is SOOOOOOOOOO EASY to gain. A single cookie can have over 300 calories. Now the regular meal should have only 500 calories. Times 3 that is 1,500 carlories a day. But we eat snacks, which adds more to regular calories intake. So its better to eat 3 solid meals than having food a little here and there.
I plan to change myself completely today, right now.
Now heres what my graph thingy on teenhealth.org looks like now:

I am THIIIIS CLOSE to be over weight.
Heres what I want it to look:

Heres what it would look like if I was 115 pounds. I thought it was ridiculous at first, then I thought about it.
I am pretty short for my age, I wont just grow out of my weight. Then I set my height as If I was 5"7':

Big difference, huh?
So I have to lose 20 pounds inorder to get to my desired weight. Its really not that hard to do the way I see it. This info was taken from many different sites, so this is just them in a nutshell.
Heres what I have to do:
First of all, STOP BITCHING AND WHINING ABOUT HOW FAT I AM. I am always comparing myself to other. Oh I wish I looked like that, I wish my whatever was that skinney and musclely. SHUT THE ******** UP AND START DOING SOMETHING ABOUT IT.
Drink water, SHITLOADS OF IT.
Look at how much calories food has, caculate it.
Avoid anything that has high amounts of suger, transfat, calories. Like cake, cookies, potato chips, soda, retarded drinks other than water ect.
Exercise. Go to the gym 3 times a week. I plan to go to different gyms on tuesday and check out the programs. Ill probably go with the one my sister Cori was going to. She lost SOO much weight. She was a skinny b***h the last time I saw here, skinnier than ME.
Do more stuff than stay on the computer. Walk my dogs, get a job, go play tennis, ect.
Get more sleep.
That is really not that hard to me. The only one that would be hard is to get my lazy a** of the computer. Why do I even stay one the computer really long anyway? No one messages me on Gaia, I have no important things such as a shop or anything, the online manga Im checking EVERY DAY only updates in a one or two months, the web comics I check up one only updates one or two pages and it takes me 1 min to read them, WHAT AM I EVEN DOING HERE????
