The Cambridge Diet is a very low calorie diet (VLCD) where under the guidance of a Cambridge Diet consultant you eat around 440 calories per day by consuming combinations of Cambridge Diet products. Men are allowed four products a day and you can choose from a variety of shakes, soups and bars, although for the first two weeks you only consume the liquid products. This should lead to an average loss of a stone a month. The diet progresses over several phases where other foods are re-introduced, until by the end you should be consuming a relatively normal diet.

Typical daily menu:

Breakfast: Cambridge Diet fruits of the forest shake

Lunch: Cambridge Diet leek and potato soup

Dinner: Cambridge Diet toffee and walnut shake

Snack: Cambridge Diet vanilla shake


  • Very quick weight loss. Although it varies from person to person, many people have reported losing up to a stone a month while doing the Cambridge diet which can be very motivating. If you can stick to it without cheating, this diet plan will give you impressive results in a short space of time.
  • You don’t have to think about food. When trying to lose weight it can be difficult to figure out what exactly you should be eating and how much, but the good thing about the Cambridge diet is that all you have to do is have the products four times a day and that’s it – no weighing, counting, measuring or trying to navigate tricky to understand nutritional labels. You don’t even have to visit a supermarket as all the food packs are given to you by your own personal weight loss consultant.
  • Support of a consultant. The Cambridge diet plan is provided by a network of Cambridge Diet Consultants based throughout the UK. These are people who have personal experience of losing weight on the plan and they’re there to support you on your journey by maintaining your personal records, answering any questions you have and cheering you on all the way.


  • It can make social situations difficult. Surviving on a diet that requires you to eat only certain products can feel socially isolating as you will be unable to join in with any food-related social activities.
  • You will miss real food. Apart from the fact that you won’t be eating any solid food, the ingredient lists for the shakes and soups are as long as your arm. In the Oriental Chilli flavour soup you have to read quite far down before you get to dried red peppers or anything that sounds like a real ingredient; skimming past things like maltodextrin, powdered cellulose, potassium chloride, soya lecithin and hydrolysed maise protein. Yum.
  • Dieters have reported all sorts of side effects to VLCDs, including fairly common ones such as headaches, tiredness, dizziness, nausea and diarrhoea and more worrying ones including hair loss, skin rashes and gallstones.
