I eat too much!!

Yesterday, I noticed that my body's changing it is my abdomen. I take a shower everyday but I didn't notice it. I don't know why but I haven't been looking my body well enough. Because usually I don't measure my weight, I didn't think I was gaining more weight. Then, I tried to figue out what my problem was. Nowadays, I try to cook myself and it is one of the reasons I guess because I can cook only one person's meal. I don't want to leave something and it means I sould eat everything. In addition, I'm not good at calculating how much is enough for one person. Also, many times I spoil many vegetables and I don't want that. So I cook too much and I don't want to leave anything. It means I eat everything. So, I gained some weight and I am almost fat........

I have to consider this as a problem. I need an excercise routine.I like to eat but, No pain No gain.....
