Protislank diet

Goal: to lose weight

Be aware: this is only the goal of this diet, not necessarily its outcome. Results vary from person to person. Consult your doctor or dietician before starting this (or any other) diet.

Protislank Diet

The Protislank diet has changed from a high-protein diet to a low-carbohydrate diet. If you follow this diet, you consume less calories than you need, with the goal of losing weight. The Protislank diet is a Dutch diet.

Pillars of the diet 

The Protislank diet has three pillars you have to stick to when following the diet. You do this in four phases, using the low-carb products and with personal online guidance of a dietician.

The four phases of the Protislank diet 

The diet consists of four different phases: The consistent phase, the moderate phase, the transition phase and the new life phase. 

The consistent phase covers 60% of the programme, the moderate phase 25%, the transitional phase 10% and the final phase 5%. The goal of this programme is to achieve a new, healthy, lifestyle.

Phase 1 - The consistent phase 

During the consistent phase, you eat 5 low-carb Protislank products per day (products with the 'phase 1' label). You may supplement these products with 250-500 grams of low-carb vegetables (from the allowed vegetables list). 

The amount of carbohydrates you are allowed consume in this phase is very limited: max. 45 grams of carbohydrates per day. In addition, you consume little fat and drink little to no alcohol. 

Phase 2 - The moderate phase 

During the moderate phase you eat 4 low-carb Protislank products (with the 'phase 1 and 2' or 'phase 2' label) and 250-500 grams of vegetables per day (again, from the allowed vegetables list). You can have a piece of lean meat (120-150 grams), fish or a meat substitute (150-200 grams) with your evening meal.

Just like in the first phase, the amount of carbohydrates should be limited to a maximum of 45 grams per day. 

Phase 3 - The transitional phase 

During the third phase you eat 3 low-carb Protislank products a day. In this phase you will reintroduce a 'normal' breakfast and a 'normal' lunch (after 2-3 weeks) in your diet. 

Just like in the second phase, you can have a piece of meat (substitute) or fish for dinner and eat lots of vegetables. You still limit your carbohydrates, fats and alcohol, but you are allowed more carbohydrates than before.

Phase 4 - The new lifestyle phase 

In this phase you eat 1 to 2 low-carb Protislank products per day. Here, you make the transition to a 'normal' eating pattern. Breakfast, lunch and dinner are now regular meals. By the end of this phase, the goals of the diet should be achieved.


It is recommended not to exercise intensively while on the diet, because the number of calories you consume in the diet are too low. However, it is recommended to walk or cycle for half an hour to an hour every day. 

Eat 5 times a day 

While following the diet you will eat about 5 times a day. The advice is to eat something every 2-4 hours. Additionally, it is recommended to drink 1.5 to 2 litres of water daily.
