Will I lose weight if i do this?

Make sure you do not starve your body of caleries. Although eating healthy is a good idea it is all a good idea to eat a veriety of foods along with regular exercise. I would suggest making an eating schudual similar to the one you have now but have different foods for each day of the week. If your body does not get these foods then it will think that you are starving yourself and all the food you eat will be trapped in the hard to target places(stomach, hips, chin and soforth) while you are buring off important fats such as the cartalege the hold your bones together.
