The program has been designed to be safe at 10 grams of protein for 1 day. It is not recommended to try the challenge for any longer than one day.

If you have a medical condition, take regular medication, have recently been unwell, are in hospital, have recently had surgery or are pregnant or breastfeeding, we strongly recommend you seek approval from your treating doctor before participating in the challenge.

10 grams a day instantly rules out a number of usual food items that you would be used to. With most foods restricted to fruits and vegetables. These need to be consumed on a limited basis and counted for protein content based on how much you consume. Some gluten free products can be found to be lower in protein. We recommend you visit our MEAL PLANS Section and plan your daily menu in advance of your PLAY date.

You can read more about the Low Protein Diet here

Foods high in protein to be avoided include; all Meats, Seafood, Nuts, Legumes, Wheat/Bread, Dairy, Pasta, Eggs and Soy.

Surprising to many, there are also many fruits and vegetables that are high in protein and can therefore only be eaten in moderation (for example, banana’s, avocado’s, potatoes, broccoli, peas etc)

Our simple easy PROTEIN CALCULATOR will take care of this for you. Simply track your meals throughout the day either by raw ingredient or by reading the labels on the packet

Yes you can, but given the drastic change in daily nutrients excessive exercise should be avoided.

If you are pregnant or breastfeeding we do not recommend you do the challenge.
