How does the GoSlank Diet work?

The GoSlank diet was put together by professionals and diet experts, to make quick and healthy weight loss possible. Thanks to the GoSlank shakes and the GoSlank diet, users lose on average 8 to 10 kilos a month. The GoSlank diet is simple to follow and super effective! With the GoSlank diet you take 2 GoSlank shakes every day. Furthermore you can eat no less than 3 snacks and a warm meal in the evening. The combination of shakes and normal food ensures that your metabolism keeps working all day, and fat is constantly being burned.

An overview of what snacks and meals are permitted can be found in the Go List and No-Go List. The Go List consists of food that is permitted during the diet and the No-Go List should be avoided during the diet.

What do you eat/drink on a day with GoSlank?

  • GoSlank shakes: In the morning and the beginning of the afternoon you drink a GoSlank shake, so that your body can burn fat all day.
  • Snacks: Divided over the day you take 3 snacks you can pick from the Go List with a maximum total weight of 100 grams. This can be one product or a combination of several products.
  • Dinner: In the evening you can enjoy a delicious dinner. This consists of 150 grams of chicken, fish or lean meat and 200 grams of vegetables. Instead of meat you can (sometimes) also use 100-125 grams of eggs, low-fat cheese or tofu. You can cook, grill, steam, oven-bake or fry with a little fluid oil.
  • Weekend: On Saturday and Sunday you can replace one of the two shakes with a meal. You can put your breakfast and lunch together from the Go List with a maximum weight of 200 grams.



How do you prepare your GoSlank shake?

Put 200 ml skimmed milk, semi-skimmed milk, unsweetened soy milk, water or soda without carbohydrates in the GoSlank shaker. Add a level measuring spoon of GoSlank powder. Put the sieve and the cap on the shaker and shake for 10 seconds. Your delicious shake is now ready to drink!
You can also stir a level measuring spoon through 200 ml skimmed yoghurt, skimmed quark or unsweetened soy yoghurt.
There is a measuring spoon in every GoSlank. It’s possible that it has become buried in the powder during transport. In that case, stir in the pot with a spoon or fork, so that the measuring spoon resurfaces. The GoSlank shaker contains a special compartment, so that you can take your GoSlank shakes anywhere!
