Depends on the breed and it takes longer if you don't have an older dog as a role model. Puppies live in the present and if you or an older dog aren't present they don't think about the rules. We used to keep the floor littered with good thinks to chew so it was easier to grab something good.
Also this next trick works very well but was reserved just for serious issues like electric cords or going after my food.
A mean continuous low growl and bared teeth with head forward and intense stare works wonders. At first you might need to add a quick charge towards them also. If they still don't listen add the momma dog move of putting them on their back and hold on the throat. Remember dogs are all about body language, and this is a strong message of back-off it's mine, and never touch it. don't over use.
Even now years later if I'm eating my dogs will not look at my food. When they do sneak a look and I turn my head towards them they quickly look away.
