Put legal restrictions on the amount of fat content in food sold off the shelves. Help stop American obesity!

I am a 14-year old kid who is husky or, obese with a lot of muscle. The amount of fat in our junk food is phenomenal. Not all fat is bad, according to Kidzworld, There are only two kinds of fats that are harmful to your body, saturated fat and trans fatty acids, unsaturated actually helps your body lower it's cholesterol levels. While saturated and trans fatty acids both raise it. What I am saying is that the government needs to execute a plan to change the american lifestyle and what we eat. I know I am not as good of a petition writer as other people but, please help me get this to Obama's desk by signing my petition!
