What You'll Learn
The Cambridge diet is a calorie-controlled diet
The Cambridge diet typically starts as a 12-week plan with very low-calorie consumption, gradually increasing to a less extreme maintenance stage. During the initial phase, individuals consume Cambridge Diet products exclusively, totalling around 400 to 600 calories per day. Over time, regular meals are reintroduced alongside the meal replacements, with total calorie intake increasing to 800, 1000, and eventually 1200 calories per day.
The Cambridge diet works by putting the body into a state of ketosis, where, due to the limited calorie intake, the body starts burning stored fat for energy instead of carbohydrates. This results in weight loss, which can be rapid during the initial phases of the diet.
There are six variations or "steps" of the Cambridge diet, each with specific guidelines for meal replacements and regular food intake. The diet is designed to be flexible and can be adapted by diet consultants to suit individual needs. However, critics argue that the extremely low-calorie intake can lead to nutrient deficiencies and adverse side effects, including bad breath, dry mouth, tiredness, dizziness, insomnia, nausea, and constipation.
While the Cambridge diet may deliver quick weight loss results, it is important to approach it with caution and consider potential health risks. It is always advisable to consult with a healthcare professional before starting any restrictive diet plan.

It involves meal replacements in the form of shakes, soups and bars
The Cambridge Diet is a calorie-controlled diet aimed at rapid weight loss. It involves meal replacements in the form of shakes, soups, and bars. The diet has been criticised for being overly restrictive and unsustainable, with potential adverse side effects such as bad breath, dry mouth, tiredness, dizziness, insomnia, nausea, and constipation. There are six variations of the diet, all of which are claimed to be nutritionally balanced and 800 calories or less per day. The diet is split into short stages, each lasting around two weeks, with the first stage being the most extreme calorie deficit and gradually increasing in calorie content before concluding with a lower-calorie maintenance plan.
The first stage of the Cambridge Diet, known as "Sole Source", involves consuming only Cambridge Diet meal replacement products, with a minimum of 600 calories per day and a maximum of 800 calories. This stage can last from one week to a maximum of 12 weeks. The second stage, or "Step 2", introduces protein-rich foods, skimmed milk, and some vegetables, with a total calorie intake of 800 calories per day. This stage lasts for a minimum of one week.
In the third stage, or "Step 3", two Cambridge Diet meal replacements are consumed along with skimmed milk, breakfast, and salads for lunch and dinner, totalling 1000 calories per day. This stage lasts for two weeks. The fourth stage continues with the same meal plan as the third stage but for an additional two weeks. In the fifth stage, one Cambridge Diet meal replacement is consumed along with skimmed milk, breakfast, lunch, dinner, and a snack, also for a period of two weeks.
Finally, the maintenance stage involves eating a healthy diet plus the option of choosing Cambridge Diet products, totalling approximately 1200 calories per day, and can be continued indefinitely. This stage is designed to help maintain weight loss and prevent weight gain. It is important to note that the Cambridge Diet should not be undertaken without first consulting a healthcare professional, as it can pose risks to health and should only be followed under medical supervision.

It is an extreme weight-loss plan
The Cambridge Diet is an extreme weight-loss plan that involves consuming very low-calorie meal replacements in the form of shakes, soups, and bars. It is a strict and highly restrictive regime aimed at rapid weight loss. The diet has been criticised by experts as being unsustainable and potentially harmful.
The Cambridge Diet, recently rebranded as the 1:1 Diet, involves a significant reduction in calories, with daily intake gradually increasing from around 500 to 1200 kcal per day. It is a six-step programme, with the first step consisting of consuming 3-4 Cambridge Diet products totalling at least 600 kcal per day. The remaining steps reintroduce regular meals while still incorporating the Cambridge Diet products.
The extreme calorie deficit created by the Cambridge Diet puts the body into a state of "ketosis," where it burns fat stores for energy instead of carbohydrates. This can lead to quick weight loss, but it is important to note that this type of starvation tactic can also have negative consequences. Experts warn that the diet may lead to nutrient deficiencies and adverse side effects such as bad breath, dry mouth, tiredness, dizziness, insomnia, nausea, and constipation.
The Cambridge Diet has been characterised as a fad diet due to its extreme nature and rapid rise and fall in popularity. It has been criticised as being unsustainable and potentially harmful in the long term. Experts caution that the rapid weight loss can create unrealistic expectations, leading to frustration and disappointment when the weight returns.
While the Cambridge Diet may deliver quick results, it is important to consider the potential risks and long-term implications for health and well-being. It is always advisable to consult with a healthcare professional before starting any extreme weight-loss plan.

It has been criticised for being unsustainable and leading to disordered eating
The Cambridge Diet has been criticised for being unsustainable and leading to disordered eating. This is due to its extremely restrictive nature, which involves putting the body into a very low-calorie deficit and entering starvation mode. While it may provide quick weight loss results in the short term, it is not a sustainable long-term solution. The diet's rapid weight loss can create unrealistic expectations, leading to frustration and disappointment when the weight returns.
The Cambridge Diet is a calorie-controlled diet aimed at rapid weight loss. It involves a strict regime of meal replacements in the form of shakes, soups, and bars, with total daily calorie intake gradually increasing as one progresses through the different stages. The number of calories consumed on this diet is close to starvation levels, which is likely to deplete energy levels and negatively impact the immune system. The diet has been described by experts as a "'starvation tactic' for the body," and there are concerns that it may lead to nutrient deficiencies and other adverse side effects such as constipation, headaches, dizziness, bad breath, dry mouth, tiredness, insomnia, and nausea.
The extremely low-calorie intake of the Cambridge Diet can also create unrealistic expectations for weight loss, as most of the weight lost will be water and lean muscle. When the diet is stopped and normal eating resumes, weight gain is likely to occur. This can lead to a cycle of disordered eating, with individuals becoming frustrated and disappointed when they are unable to maintain the extreme weight loss results.
Additionally, the Cambridge Diet has been criticised for being difficult to create at home, as it requires the purchase of specific meal replacement products. This can be costly, as people must buy at least two weeks' worth of products at a time. The diet has also been the subject of controversy, with potential health concerns raised and even some documented deaths potentially linked to the diet.
Overall, while the Cambridge Diet may provide short-term weight loss results, it is not a sustainable long-term solution and may lead to disordered eating behaviours and negative health consequences.

It may help manage Type 2 diabetes
The Cambridge diet is a calorie-controlled, very low-calorie diet (VLCD) aimed at rapid weight loss. It involves consuming meal replacements in the form of shakes, soups, and bars, alongside protein-rich foods, skimmed milk, and some vegetables. The diet is extremely restrictive and involves putting the body into a very low-calorie deficit, which can lead to quick weight loss results in the short term.
The Cambridge diet has been included in the largest study of diabetes prevention, and research suggests that VLCDs may help manage Type 2 diabetes. However, it is important to note that strict calorie restriction can pose risks, such as nutrient deficiencies, constipation, headaches, and dizziness. Additionally, the number of calories consumed on the Cambridge diet is close to starvation levels, which can impact energy levels and the immune system.
While the Cambridge diet may provide quick results, it is essential to consult with a healthcare professional before starting any extreme weight loss plan, especially for those with pre-existing health conditions like Type 2 diabetes. The NHS also offers a Type 2 Path to Diabetes Remission programme (T2DR) with Oviva, which shares similarities with the Cambridge diet in terms of consuming a lower-calorie diet for short-term weight loss. This programme may be a more sustainable and safer option for managing Type 2 diabetes.
Overall, while the Cambridge diet may help manage Type 2 diabetes by promoting weight loss, it is crucial to prioritize health and sustainability under the guidance of medical professionals.
