Okay so if i ate one bag of chips and whatever is served for dinner only everyday. Would I lose weight?

The bag of chips would be like (Baked Lays, Baked hot cheetos, Cheesets, Sunchips, Kettle Corn, Pretzals etc.) and for dinner my parents usually serve a salad, meet, noodles, or lasagna. My question is tho tech is im not eating much so would i lose weight? (Plus id only drink water)
