Jesus H. Christ, there is nothing wrong with eating cereal! Just choose one that is not loaded with sugar.

Eat oatmeal, total, cheerios, corn flakes, raisin bran, grape nuts. Add some fruit if you want.
I had hot oatmeal with low fat milk and a banana for breakfast yesterday. It was delicious, nutritious and I did not get hungry again for several hours (and I have low blood sugar)

Do you want to lose weight? I mean, you do, don't you? That is what you've said.

Eat less junk food, cut down on fatty foods, add more healthy nutritious food to your diet (meaning lots of vegetables and fruits), add fiber-rich foods to your diet, drink plenty of water every day, and get some exercise.

It's not rocket science, and despite the plethora of tips on this   thread, it is not complicated. What is stopping you? It is not   necessarily easy,but if you don't at least make an effort, nothing   will happen.

Please, please, just do something to get started.
