The Cambridge Diet, officially known as The 1:1 Diet, is a structured weight-loss program that utilizes meal replacements to create a very low-calorie intake, putting the body into a state of ketosis. For many people, a daily cup of tea or coffee is a non-negotiable routine. The good news is that these beverages are permitted, but only under certain strict conditions that vary depending on which 'Step' of the diet you are following. The key principle is to avoid adding calories from milk, sugar, or other flavourings, especially during the more restrictive phases.
Step 1 (Sole Source): The Strictest Rules for Tea and Coffee
During the initial and most restrictive phase of The 1:1 Diet, you consume only the designated meal replacement products. This very low-calorie stage requires careful management of all fluid intake to ensure you remain in ketosis and meet your nutritional requirements.
- Black is the Only Option: On Step 1, both tea and coffee must be consumed black. Adding milk or sugar is strictly forbidden as these contain carbohydrates and calories that can disrupt the ketosis process and stall weight loss.
- Decaffeinated is Recommended: For those who drink large quantities, decaffeinated options are preferred. The plan acknowledges that caffeine acts as a stimulant and can cause an irritant effect in some individuals.
- Managing Caffeine Withdrawal: If you are used to a high caffeine intake, you may experience withdrawal symptoms, including headaches, in the first few days. The diet's plan recommends reducing caffeine intake slowly in the week before starting to help mitigate this effect.
Steps 2-5: Expanding Your Beverage Choices
As you progress through the program, your consultant will guide you through steps that gradually reintroduce conventional food. This expansion of food options also loosens some of the beverage restrictions.
- Milk is an Option: From Step 2, a small amount of skimmed milk may be permitted. This allowance should be discussed with your consultant, who will advise you on the specific quantity. For example, 50ml of skimmed milk is approximately 18kcal and may be factored into your daily intake.
- Herbal and Fruit Teas: Herbal and fruit teas are excellent alternatives and are generally allowed throughout the plan as a calorie-free, hydrating choice. These can provide variety and help curb cravings for more flavourful drinks.
- Occasional Low-Calorie Drinks: From Step 2 onwards, you may also have occasional low-calorie or diet drinks. However, these should not replace your essential water intake and should be used sparingly.

Alternative Drinks and Key Considerations
Beyond standard tea and coffee, The 1:1 Diet provides other options and requires careful consideration to manage your journey effectively.
Approved Alternatives
- Herbal and Fruit Teas: A wide variety of these, such as chamomile or peppermint, can provide a flavour boost without calories.
- CWP Water Flavourings: The plan offers its own range of water flavourings, providing a tasty way to increase your fluid intake.
- On-Plan Coffee-Flavoured Products: The 1:1 Diet includes options like the 'Latte Shake 'N' Go' or cappuccino-flavoured shakes, which can be a satisfying coffee alternative within your daily meal replacement allowance. You can also use a flavoured shake to 'whiten' your black coffee.
Crucial Considerations
- Hydration is Key: The plan mandates drinking at least 2.25 litres of water daily, separate from tea or coffee. This is essential for overall health and to manage side effects like headaches and constipation. Drinking plenty of water also helps the body flush out waste products from fat breakdown.
- Listen to Your Body: Caffeine affects people differently. If you experience restlessness, increased anxiety, or difficulty sleeping, it may be a sign to reduce your caffeine intake.
- Consult Your Expert: Always check with your personal consultant regarding any questions about drink allowances. They can provide tailored advice based on your specific plan and health situation. For example, they may advise decaf over regular coffee or specify milk limits.
Conclusion
While the answer to "Can you drink tea and coffee on a Cambridge diet?" is yes, it comes with clear, step-specific instructions. During the intense initial phases, these beverages must be consumed black to avoid disrupting ketosis. As you progress through the program, a limited amount of skimmed milk may be re-introduced. It is vital to remember that tea and coffee do not replace your daily water intake, which is critical for preventing dehydration and managing side effects. By understanding and adhering to these rules, you can continue to enjoy your favourite hot drinks while successfully navigating your weight-loss journey with The 1:1 Diet.
