I am on diet

What is the best thing to eat when you are on diet? Please refer below for details:

1) Eat fast food once a week
2) Drink your favourite soda one can per day
3) Pizza Night (more tomato sauce, vegetables but not meat on top)

You know what I did? I took cereal with low-fat milk for lunch and seaweed drinks for breakfast and dinner. That would really do the job of pushing the fats away. The above trick will still maintain the fats in you, I bet.

Have fun..
