What Is The Proteifine Diet?

If you are looking for a safe and effective way to lose weight quickly and keep it off for good, Proteifine may well be the solution for you. We have worked with Proteifine since it was first introduced to the UK in 2010 and can confidently say that it is one of the most effective approaches to weight loss. It’s enabled our team and to support hundreds of clients in reaching and maintaining their healthy, happy weight.

Schedule a complimentary weight loss strategy call with one of our nutritionists today to find out if Proteifine is the right diet for you.

Here are a few commonly asked questions about the Proteifine Diet.


Proteifine is a protein based, low carbohydrate weight loss programme that promotes rapid fat loss. Proteifine, developed by Ysonut Laboratories, was launched in France almost 20 years ago. The diet is only available through trained doctors and nutritionists to ensure it’s tailored to your needs and carried out in a safe, healthy and effective way.


While everyone is different, our clients typically lose around one stone / 7kg per month whilst on Proteifine. We have used the diet with clients who wanted to lose several stone and those who just wanted to lose that last half a stone. It is effective regardless of how much weight you have to lose.

You might have seen the story of Martina Coogan’s eight and a half stone (55kg) weight loss on the MailOnline. Martina (who volunteered to share her story), lost almost half her body weight in just over a year, using the Proteifine diet plan.


Proteifine consists of a wide range of specially designed foods that are rich in natural proteins but low in carbohydrates. The good news is, they taste surprisingly good and include a number of savoury and sweet foods, including chocolate options! The range includes bars, biscuits, desserts and pancakes as well as savoury foods like pasta, omelettes, toasts and savoury snacks.

There’s something to suit everyone’s taste. Whilst on the Proteifine Diet you can also consume a range of fresh vegetables, herbs, spices and olive oil alongside the Proteifine foods.


By reducing your intake of carbohydrates the body switches to a state of ketosis where it breaks down body fat to burn as it’s main source of energy. This is a very effective way to lose weight quickly and healthily. Proteifine is provided only by doctors and nutritionists to ensure it is tailored to your individual needs and is followed correctly so as to ensure it’s safety and efficacy.


Yes, absolutely. It is a great approach to weight loss for vegetarians. The vast majority of the products in the range are vegetarian. If you are a vegetarian considering the proteifine diet, read our guide here.


Many people worry that they will suffer from hunger and low energy levels on the diet, but this rarely happens. Conversely, most people find that their energy levels improve significantly and their cravings and hunger pangs disappear. During the first couple of days, before the body enters ketosis, hunger can occur, but this is only temporary.

So how does the diet boost energy and prevent hunger? Typical carbohydrate based diets can cause cravings and fluctuations in energy levels. Proteifine products are based on protein which is satisfying and provides slow releasing energy.  Protein is naturally very satisfying. Many of our previously big-portion-loving clients report that they don’t feel the need to eat anywhere near the quantity of food they used to during and after the diet.

Positive side effects of the diet include improved skin health, reduced cellulite, decrease in digestive issues, improvements in concentration and mental alertness to name just a few.


Unlike other low calorie diets, the Proteifine Diet ensures that you are unlikely to end up with sagging skin. This is because the diet provides an optimal amount of easily digested protein. As your skin collagen and elastin structures are made from proteins, the protein in your diet will support your skin structure and elasticity, helping to prevent sagging skin. Many of our clients see an improvement in skin quality during and after the diet.


Few things are more frustrating than putting a lot of effort into losing weight, only to put it all back on again after finishing the diet. There are a number of reasons why this is unlikely with Proteifine.

Firstly, it is often due to a loss in muscle mass that our basal metabolic rate (the rate at which we burn calories) is reduced. Due to the protein content of Proteifine, your muscle mass and basal metabolic rate are not only maintained, they can sometimes even increase.

Secondly, nutritional re-education is a key component of the Proteifine Diet. As you gradually reintroduce traditional meals into your diet, you will gain an in depth understanding of how to eat to optimise your health and maintain your weight long term. Many of our clients enjoy the Proteifine products so much (especially the bars and chocolate shakes!) that they continue to order them long after they have finished the diet. This helps to satisfy a sweet tooth or provide a quick and healthy breakfast/snack, without the consequence of regaining weight.

Finally, we combine the diet with health coaching to uncover self sabotaging behaviours that have kept you overweight and enable you to form new, healthier habits to make sure your results are maintained long term.


Most of our clients find the diet much easier to stick to than they expect. The products are tasty and simple to prepare (many require no preparation at all) making it easy to fit around a busy lifestyle. The diet is also tailored to you and your life. You are not committed to sticking to a regimented programme – if you need to eat out at a restaurant, or you wish to eat a home cooked meal with your family in the evening, the diet can be tailored to allow this.

The natural amino acids tryptophan and tyrosine are used to help control cravings and mood swing, regulate appetite and sleep patterns and help optimise your mental state whilst on the diet. Research has shown that incorporating these two nutrients further increases your chances of sticking to the programme.


No, it’s not.

Ketosis is the metabolic process that is responsible for the rapid weight loss seen with The Atkins Diet – this also occurs with Proteifine. However there are a number of key differences between Proteifine and Atkins.

The Atkins Diet is a low carbohydrate plan, but the intake of both fat and protein is unlimited. Excessive intake of anything can result in health problems. The Proteifine Diet is a protein based diet but not a high protein diet. The diet is tailored so as to provide an optimal intake of protein based on your individual needs. It provides specific amounts of essential fats and less than 40g carbohydrates per day, so as to induce ketosis. This promotes effective, safe and healthy weight loss, focused on maintaining lean body mass (muscle, skin etc) while reducing your body fat.

Tailored micronutrient supplementation is provided to ensure you are optimally nourished.

While on Proteifine you will be constantly monitored and supported by your practitioner who is trained and experience in working with the diet.


During Phase One when you only consume Proteifine foods (plus vegetables), the food and supplements together costs around £23 per day, depending on which products you choose. If you have a specific budget in mind then we will always do our best to work to this with you.

For the first month, weekly consultations are advised. After your first month, you may wish to have consultations every other week. Consultation fees are additional to the cost of the Proteifine products.
