Step 1, also known as 'Sole Source', involves eating only Cambridge Diet meal replacements
The Cambridge Diet, recently renamed the 1:1 Diet, is an extreme weight-loss plan that involves eating only Cambridge Diet meal replacements. It was developed for people with clinically severe or "morbid" obesity, which involves a body mass index (BMI) of 40 or higher. The diet follows six staggered "steps", starting with Step 1, also known as "Sole Source". During this step, individuals exclusively consume Cambridge Diet meal replacement products, such as shakes, soups and bars. These products are designed to fulfil daily nutritional requirements and are claimed to be nutritionally balanced, containing 200 calories or less. Women whose height is under 172cm (5’8”) will have three Cambridge Weight Plan products per day, while women who are 172cm (5’8”) and above will have four, as will all men. In addition to these meal replacements, individuals can include tea and coffee, herbal and fruit teas, Cambridge Water Flavours, and occasional low-calorie or diet drinks. If a Ready to Drink Shake or a Bar is consumed, an additional 250ml of fluid is recommended.
Step 1 of the Cambridge Diet typically lasts for up to 12 weeks and is characterised by a very low-calorie approach, with individuals consuming around 400 to 800 calories per day. This extreme calorie deficit leads to rapid weight loss, which is a key appeal of the diet. However, it is important to note that this type of very low-calorie diet (VLCD) is not suitable for everyone and may pose certain risks. The number of calories consumed is close to starvation levels, which is likely to result in low energy levels and a weakened immune system. Additionally, the restrictive nature of the diet may negatively impact an individual's relationship with food, their social life, and their mental well-being. There is also a high risk of weight regain once a normal eating pattern is resumed.
While the Cambridge Diet has been praised for its potential effectiveness in managing Type 2 diabetes and promoting rapid weight loss, it has also been criticised for being unsustainable and potentially unsafe. The diet is considered extremely restrictive, and concerns have been raised about the risk of nutrient deficiencies and other undesirable outcomes such as constipation, headaches, and dizziness. The long-term sustainability of the diet is questionable, and there may be negative consequences for both physical and mental health. Furthermore, the cost of the Cambridge Diet products has been highlighted as a potential barrier, with expenses of around £51.00 per week for the shakes, bars, and products.
Despite the potential benefits of rapid weight loss, individuals considering the Cambridge Diet should carefully weigh the risks and benefits. It is important to consult with a healthcare professional before starting any extreme diet plan to ensure it is safe and appropriate for your individual needs. Additionally, it is worth exploring more sustainable and enjoyable approaches to weight loss that focus on whole foods and adequate micronutrient intake.

The first step lasts 12 weeks and is very low calorie, with meals totalling 400-800 calories
The Cambridge Diet is a rapid weight-loss plan that has been described as an extreme and unsustainable approach to shedding pounds. The first step, also known as 'Sole Source', lasts 12 weeks and is very low calorie, with meals totalling 400-800 calories. During this phase, individuals consume exclusively branded meal replacement products in the form of shakes, soups and bars. These products are designed to fulfil daily nutritional requirements and create a large calorie deficit to induce rapid weight loss.
The number of meal replacements consumed per day depends on factors such as gender and height. Women whose height is under 172cm (5’8”) will have three Cambridge Weight Plan products per day, while women who are 172cm (5’8”) and above will have four, as will all men. In addition to these meal replacements, individuals can include tea, coffee, herbal and fruit teas, Cambridge Water Flavours, and occasional low-calorie or diet drinks. If a Ready to Drink Shake or a Bar is chosen, an additional 250ml of fluid is recommended.
While the Cambridge Diet may deliver quick results, there are concerns about its safety and sustainability. The very low-calorie approach can lead to nutrient deficiencies and adverse side effects such as constipation, headaches and dizziness. It is also incredibly restrictive, which can make it challenging to adhere to in the long term. The extreme calorie deficit may also put individuals into starvation mode, impacting energy levels and immune function.
Despite the potential risks, the Cambridge Diet has been praised for its one-to-one consultant support. Dieters work closely with consultants to create individualised plans and receive guidance throughout the different stages. This additional support provides accountability and has been shown to increase success rates. However, some reviewers have expressed disappointment with the level of support received, noting that it fell short of their expectations.

The Cambridge Diet is controversial, with some saying it is unsustainable and may negatively affect health
The Cambridge Diet is a very-low-calorie meal replacement diet that was developed in the 1960s. It has been characterised as a fad diet due to its starvation-level calorie intake, extreme weight loss, and rapid rise and fall in popularity in the 1980s. The diet is controversial and has faced scrutiny from regulators and health authorities due to potential health concerns. It has been linked to several deaths, and there are concerns about its sustainability and potential negative impact on health.
The Cambridge Diet is a strict regime that involves consuming meal replacements in the form of shakes, soups, and bars. It is designed to be a rapid weight-loss plan, with the first 12 weeks being quite drastic in terms of calorie restriction, creating a large calorie deficit. While it may provide quick results in the short term, it is considered extremely restrictive and unsustainable in the long term. The diet starts with a very low-calorie intake of around 400-600 calories per day for up to 12 weeks, which is followed by a gradual increase in calories before concluding with a lower-calorie maintenance plan that includes optional Cambridge Diet meal replacement products.
The controversy surrounding the Cambridge Diet stems from its potential health risks and lack of long-term sustainability. The diet's very low-calorie approach can lead to nutrient deficiencies and adverse side effects such as constipation, headaches, dizziness, bad breath, dry mouth, tiredness, insomnia, and nausea. The calorie intake is close to starvation levels, which can result in low energy levels and a weakened immune system. Additionally, the extreme restriction of food choices can make the diet boring and challenging to maintain, potentially affecting an individual's relationship with food, social life, and mental well-being.
There is also a high risk of weight regain once a person returns to a normal eating pattern, which can undermine self-esteem and lead to a negative relationship with food. The rapid weight loss achieved through the Cambridge Diet can create unrealistic expectations, causing frustration and disappointment when the weight returns. Furthermore, the diet may not provide a sustainable approach to long-term health and well-being, as it does not educate individuals on how to create a positive relationship with food or how to maintain a healthy weight in the long term.
The Cambridge Diet has evolved to include more support and personalisation, with the addition of a 'personalised consultant' to work with the dieter and provide guidance and accountability. However, despite this additional support, the very low-calorie nature of the diet and the potential health risks associated with it remain a concern for some.
