Post workout shake

We wouldn’t recommend taking the Fat Metabolisers, Carb Blockers or Hunger Buster capsules as these can be detrimental to the health of your baby. For more advice, drop an email to our nutritionists - advice@proteinworld.com. 


Do your products contain nuts?

It's best to check individual ingredient lists. We do follow cross-contamination measures, however some of our products are made in a factory that handles nuts, so we cannot guarantee they're 100% nut-free! If you have any concerns or questions please email advice@proteinworld.com.

Can women and men use Protein World products?

Absolutely! Every single one of our products can be used by either men or women.

What product is best for me?

How do I incorporate the boosters into my day?

Can I have a healthy meal for lunch and shake for dinner instead?

The Slender Plan is designed to work around you. Therefore, you can replace whichever meals you like with the Slender Blend and Slender Porridge. We just recommend having one nutritious wholefoods meal a day (whether this be lunch or dinner).

Do I need to exercise whilst on the Slender Plan?

You can lose weight without exercising. However, exercising (in particular HIIT and resistance training) will help to maximise fat loss results.

Do I have to follow the recipes in the booklet?

The recipes in the book are just a guideline that follow the recommended calorie and nutrient intake. However, feel free to get creative with your own recipes. If you need more inspiration we have lots of recipes available on our recipes page.

What else can I snack on?

  • 1tsp of peanut butter with sliced apple
  • Hummus with vegetables (carrots/celery/peppers/cucumber)
  • Total 0% fat yogurt with some berries
  • Boiled egg
  • Turkey/chicken breast
  • Handful of nuts (almonds, walnuts, brazil nuts).
