A common mistake of people interested in losing weight is don't having a breakfast.
They think this way they'll reduce the number of calories in their body, but that's not true.
When you don't have a breakfast, you don't provide the body with the enough energy to start the day with strength. Also in a few hours you will be hungry, and guess what? next time you eat, you will eat a lot more because of this hunger, so that calories you where thinking to avoid, will be in your body and who knows if there would be more...
So, I want to say you today, have a great breakfast. You can eat cereals, fruit, yogurts, juices, milk, toasted integral bread... all these are good for that first meal of the day.
Now the question is, are you having a good breakfast?
