Will i lose weight with my diet and exercise plan?

You need carbs for energy to do your exercising, and no teas with caffeine. Make sure the elliptical is doing cardio, as you'll lose weight and just get stronger in general. DO NOT exercise after dinner, because that will just make you hungry again and make you want to eat something late at night, and don't eat right before you go to bed. Drink lots and lots of water. Other than that, sounds good!
