Your Questions, Answered.

The term meal replacement has been around for many years. However, with the major advances in understanding human health and food nutrition, Diet Meal Replacement is now more akin to a nutritionally complete meal. So rather than replacing a meal, think of it as a liquid meal packed with an array of health-boosting macro and micro nutrients.

Diet Meal Replacement is one of our best-selling products and loved by customers with 92% saying they would buy it again*. It comes in a range of delicious flavours and provides a precise serving of each key macro and micro nutrient. This means we do all the heavy lifting for you to ensure you consume a balanced amount ratio of protein, fibre, carbs, fats, and so on.


*Based on a survey of our customers conducted in 2024. 

Diet Meal Replacement has a number of ingredients specifically designed to keep you feeling fuller for longer. This is key when it comes to achieving your weight loss goals. In addition, the serving size provides as little as 245 calories which helps create the calorie deficit that is required in order to reduce weight. There’s also a wide range of essential vitamins and minerals included in each serving to contribute to your recommended nutritional intake.

They are both great products, but Diet Meal Replacement is the O.G. - the original - with over 1,200 product reviews and 176 health benefits locked into a single shake. It offers incredible value for money, giving unbelievable bang for your buck.

To support weight loss, you should replace two of your main daily meals with a 70g serving as part of an energy restricted diet. However, to support weight maintenance after weight loss, replace one of your main daily meals with a 70g serving as part of an energy restricted diet.

Absolutely! Just think of it as a normal daily meal. As always, check the label of any supplement you are looking to take for allergies and intolerances. Our nutritionists recommend you try Hunger Killa, Thermopro Burn Ultra and Super Greens Extreme for optimal results

It’s suitable for vegetarians, but unfortunately not for vegans. However, we have developed a vegan-friendly version called Vegan Diet Meal Replacement, which is ideal for vegans or anyone wanting to reduce their dairy intake.

Unfortunately, Diet Meal Replacement is not suitable for those who are on a gluten-free diet.

Meal replacements contain a balanced ratio of protein, fibre, fats, carbs and micronutrients, and are being designed to be nutritionally complete. A protein shake usually contains a very high protein content and is primarily made from pure protein sources, and then enhanced quite often with additional active ingredients to support specific body or performance goals.

  1. Great Shakes

    Absolutely love the Millionaires Shortbread flavour, I prefer to make my shakes thicker and they are so filling that I’m not hungry between meals.
  2. Highly Recommended

    I ordered 2-weeks worth of the Diet Meal Replacement shakes. Banana Smooth, Vanilla Creme, Millionaire's Shortbread, Chocolate Silk and Strawberries n Cream. Millionaire's Shortbread and Vanilla Creme are definitely my favourite flavours. I mix with water to try and keep my calories for my evening meal. I ordered the extreme shake for my third week, I've reviewed them seperately. I am just coming to the end of my 3rd week, having the shakes for breakfast & lunch, and I have lost 1 stone. Just for clarity - I go to 4 gym classes a week and have a half hour seession with my PT weekly. These are really handy, I make a shake before I leave for work, and then take an empty shaker and a tub of the powder and make them at work for lunch. I normally use a blender and ice at the weekends when I have a bit more time. I find using less water to make them thicker, leaves me fuller for longer.
  3. Millionaire's Shortbread is a winner!

    I've had both the Extreme and ordinary Diet Meal Replacements, and notice no difference other than the 50 calories or so gained per meal, except that the Millionaire's Shortbread is so good it's worth the extra 50 calories - the oaty undertones really evoke a good biscuit-y base, and the aftertaste is great. They mix very well, fill me up for the afternoon (I've having an Extreme for breakfast and regular Diet Meal Replacement for lunch), they are supporting a good pace of weight loss, they're supporting my protein intake and I don't seem to be suffering any reduction of athletic performance, and my body generally feels happy.
  4. Weight loss

    Wow!! The diet meal replacement absolutely amazing, I've only been using just over a week and i don't feel hungry. Delivery was superb, thank you.
  5. Really good

    Overall, it's a nice product. Today i have had caramel macchiato. My only negative comment is that it is a bit too sweet for my taste buds. It is filling and satisfying.
