Simple answer - no.
To lose weight, your body needs to burn more energy than you put into it. Calories are that energy. As long as there is energy from outside sources (food), your body won't use fat (and other stuff) in your body to produce the needed energy. Only if there is a deficit of energy it will start to use up the reserves (fat).
In other words, as long as you are not in a caloric deficit, you will not lose weight.
