I need a good diet plan?

i drink only water everyday. no soda or anything. i drink about 5 to 8 bottles a day and in one week i lost all my chubbyness. i thinned out wicked fast. now i go to the gym 3 to 4 times a week and keep up with the water and just eat good foods like carrots and fruits and it just falls off if you stick with it. its simple and pretty fast
