What You'll Learn

Alcohol is not recommended on the Cambridge Diet
The diet has been criticised for its health implications. The British Dietetic Association lists the possible adverse side effects as including "bad breath, a dry mouth, tiredness, dizziness, insomnia, nausea and constipation". In 2005, the American Academy of Family Physicians recommended avoiding fad diets such as the Cambridge Diet. The diet has also been criticised for its cost, as people must buy at least two weeks' worth of product at a time.
Alcohol is considered to be a major obstacle to any diet, as it is high in calories and has no significant nutritional value. Alcohol can also have the effect of making you very hungry and lowering your willpower, which is counterproductive when trying to lose weight. The Cambridge Diet is a very low-calorie diet, and alcohol consumption can slow down weight loss.
The diet consists of five steps, and dieters are asked to stop drinking alcohol throughout all of them. During the first few steps, dieters are only allowed to drink water, herbal tea, or regular tea and coffee without milk. Milk is also restricted to 200ml a day and must be skimmed.
If you are considering the Cambridge Diet, it is important to consult a healthcare professional first.

Alcohol is high in calories
Alcoholic drinks are often high in calories and can quickly add to your daily intake. For example, going out for a couple of drinks can add 500 calories or more to your daily intake. Alcohol is considered empty calories because it cannot be metabolised as fuel but must first be deposited as fat in the body before it can be used to fuel us.
The Cambridge Diet is a popular UK diet that provides portioned meals and one-on-one professional support to those following a tailored weight loss programme. It is a very low-calorie diet with a daily intake of 600-800 kcal per day. The diet has been criticised for being unsustainable and not based on fresh foods. One of the biggest things to avoid when on the Cambridge Diet is alcohol. Alcohol is not permitted on the diet, not because it is a killjoy, but because it is considered unsafe.
If you are following the Cambridge Diet, it is important to avoid alcohol to stay within the very low-calorie intake. As alcohol is high in calories, drinking it can quickly increase your daily calorie intake, hindering your weight loss progress. Additionally, alcohol can lead to the drunk munchies, increasing your calorie intake even further.
If you are craving a drink, there are some lower-calorie alcoholic options, such as a small dry red wine, which can help purge excess sub-cutaneous fluids. However, it is important to note that alcohol is still considered empty calories and is not a good source of nutrients. It is always best to speak to a healthcare professional for advice on drinking alcohol while on a diet.

Alcohol can be replaced with water, tea, or coffee
The Cambridge Diet is a very-low-calorie diet with 6 variants or "steps". The diet plan involves replacing meals with shakes, soups, ready meals, bars and snacks. The first step consists of 3-4 products totalling at least 600 kcal per day. The remaining steps reintroduce regular meals and remove the 1:1 products in various combinations.
The Cambridge Diet is one of the most popular diets in the UK. It is considered a quick-fix extreme diet that works fast to achieve results due to its low-fat, low-carb, and low-calorie focus. However, it is not a sustainable or healthy long-term approach to weight loss. The diet has been criticised for its use of processed foods, high cost, and potential adverse side effects such as bad breath, dry mouth, tiredness, dizziness, insomnia, nausea, and constipation.
Alcohol is strongly discouraged on the Cambridge Diet. Alcohol is considered empty calories and can hinder weight loss. It can also have negative effects on ketosis, a common side effect of low-carbohydrate diets, and increase the risk of serious health issues such as liver and kidney damage.
Instead of alcohol, dieters on the Cambridge Diet are advised to drink water, herbal tea, or regular tea and coffee without milk. Staying hydrated is important, especially for those experiencing constipation as a side effect of the diet. Water can be flavoured, and tea and coffee can be whitened with a small amount of vanilla shake. These alternatives provide hydration without the negative effects of alcohol on weight loss and overall health.

Alcohol can be dangerous when combined with the Cambridge Diet
Secondly, the Cambridge Diet is a low-carbohydrate diet, and such diets can lead to ketosis, a state where the body does not get the calories or nutrition it needs for energy, so it starts burning its fat stores and lean muscle. Ketosis can result in serious damage to the kidneys and liver if continued for an extended period. Alcohol can increase the risk of ketosis, as it provides empty calories and no significant nutritional value.
Thirdly, the Cambridge Diet is a meal-replacement programme, where most or all of a person's daily food intake is replaced with specially formulated products such as shakes, soups, bars, and porridge. These products are designed to be low in calories but still high in essential nutrients. However, alcohol can disrupt the balance of nutrients in the body, as it has no nutritional value and can increase hunger and lower willpower. This could lead to nutrient deficiencies and a disruption of the weight loss process.
Finally, the Cambridge Diet is a restrictive and unsustainable diet that can be expensive and stressful. Alcohol can be a barrier to adherence to the diet, as it is often consumed socially and can be difficult to avoid when going out or socialising. This could lead to a disruption of the diet plan and potentially negative health consequences. Therefore, it is recommended that alcohol be avoided while on the Cambridge Diet to ensure safety and maximise the chances of success.

The Cambridge Diet is linked to rapid weight loss
The Cambridge Diet, now rebranded as the 1:1 Diet, is a very-low-calorie meal replacement plan. It was developed in the 1970s at Cambridge University by Dr Alan Howard, who wanted to create a diet for morbidly obese patients. The diet has been characterised as a fad diet due to its extremely low-calorie intake, rapid weight loss, and its rise and fall in popularity in the 1980s.
The diet consists of 6 steps or variants. The first step involves consuming at least 600 kcal per day through Cambridge Diet products. The remaining steps involve reintroducing regular meals and removing the 1:1 products. The diet recommends that dieters avoid alcohol, as it is considered to be the "biggest anti" when it comes to dieting. Alcohol contains empty calories and no significant nutritional value. It can also lower willpower, which is detrimental when trying to lose weight.
The Cambridge Diet advises inducing ketosis as a healthy process for weight loss, but most of the medical community disagrees. Ketosis can result in serious damage to the kidneys and liver if continued for an extended period. Another potential side effect is the development of gallstones, as rapid weight loss increases the risk of gallstones, and one-fourth of people on very-low-calorie diets are diagnosed with gallbladder issues.
Overall, the Cambridge Diet is linked to rapid weight loss due to its focus on creating a significant calorie deficit through low-calorie, low-fat, and low-carb meal replacements. However, it is important to consider the potential risks and side effects associated with the diet.
