How long does it take to loose weigh with yoli?

The same as it takes with any other weight loss plan. Eating 3500 calories under maintenance = a pound of weight loss. How long it takes to lose weight depends on how much of a deficit you are running.

This does not apply to water weight. Many fad diets will have you shedding water weight and claiming this as proof of the efficacy of the diet. Don't be fooled.
