What are the best workouts for a full body beginner workout ?

Hi, I'm a 22 year old guy standing 5'9 weighing 266 pounds and I need to lose my gut and I need advice to reach my goal. I'm a beginner and I want some tips on how to structure my workout.I want to burn a lot of fat and gain muscle but in a sustainable and realistic way of course.
Would anyone willing to give me advice ?
