Fastest and easiest is to get liposuction. Exercise and diet is hard work and takes discipline. You may not see results so quickly but overall it is the best way to keep the kgs off.
Besides the normal stuff, exercise, eat multiple small portions and get well rested, I would say drink a lot of water. Water helps in cutting weight tremendously and keeps your body working well.
I can't give you a workout plan or diet but DO DRINK WATER.
