The short answer is yes, plain black coffee is allowed on the cabbage soup diet. However, this simple answer comes with a significant caveat: no additions. The restrictive nature of this seven-day fad diet means any extra calories, fats, or sugars can compromise the intended rapid weight loss. The goal of the diet is a very low-calorie intake, which means every item consumed is scrutinized for its caloric impact.
The Simple Rules for Drinking Coffee
If you choose to include coffee in your seven-day regimen, you must adhere to strict guidelines. Any deviation adds calories and can interfere with the diet's mechanism, which relies on a severe caloric deficit.
- Black is the only option: Your coffee must be served black, with no room for milk, cream, half-and-half, or other dairy products.
- No sweeteners: Sugar, honey, artificial sweeteners, or any flavored syrups are strictly forbidden. The diet avoids all forms of added sugar.
- Moderation is key: While no specific limit on black coffee is often stated, it's wise to consume it in moderation. The high caffeine content can contribute to dehydration, which is a concern on this already fluid-focused diet.
- Unsweetened tea is also an option: If you prefer, unsweetened herbal tea or regular tea is also a permissible beverage choice.
Why Additives Matter
The rigid nature of the cabbage soup diet is built on consuming very few calories. This is why any added ingredients, no matter how small, are forbidden. A tablespoon of cream, a packet of sugar, or a flavored syrup introduces calories and carbohydrates that sabotage the diet's premise. The diet's framework is designed to force your body to burn stored glycogen and water, which results in the rapid, though temporary, weight loss proponents promise. By adding milk or sugar, you provide your body with an alternative energy source, preventing this process from occurring efficiently.
Understanding the Cabbage Soup Diet's Approach to Liquids
Staying hydrated is crucial on this diet, and alongside cabbage soup, you have a few select options. The diet's emphasis is on calorie-free or very low-calorie fluids to flush the system.
| Allowed Beverages | Not Allowed Beverages | 
|---|---|
| Water (main source of hydration) | Alcoholic beverages | 
| Black Coffee | Regular soda or diet soda | 
| Unsweetened Tea (Herbal or regular) | Sweetened juices or beverages | 
| Cranberry Juice (Unsweetened, on specific days) | Cream or milk in coffee (except skim milk on Day 4) | 
| Skim Milk (Only on Day 4) | Artificial sweeteners | 
Potential Downsides of Combining Coffee and This Diet
While allowed, consuming coffee on the cabbage soup diet is not without its risks and potential complications. The side effects of this diet can be exacerbated by the stimulant effects of caffeine.
- Increased Dehydration: Caffeine is a mild diuretic, meaning it can cause your body to excrete more fluid through urination. On a very low-calorie diet where hydration from a balanced diet is already compromised, this can increase the risk of dehydration.
- Exacerbated Side Effects: Common side effects of the cabbage soup diet include headaches, dizziness, and fatigue due to the severely low calorie count. Caffeine can heighten anxiety and may contribute to or worsen these symptoms for some people.
- Digestive Discomfort: Both cabbage and coffee can contribute to digestive issues like gas, bloating, and an upset stomach, especially when consumed in large quantities. The combination can be particularly hard on your digestive system.
- Nutrient Deficiencies: The diet already lacks essential fats, proteins, and many micronutrients. Over-reliance on coffee as a substitute for real food can worsen these deficiencies. It's especially dangerous for individuals with pre-existing conditions like diabetes, as the diet's extreme nature can cause dangerous blood sugar fluctuations.
An Important Consideration Before Starting
Before starting any restrictive eating plan like the cabbage soup diet, it's crucial to understand the risks. The diet is not scientifically supported as a healthy, sustainable weight loss method. Weight lost is often regained, and the restrictive nature does not teach long-term healthy eating habits. For a truly sustainable approach to health and wellness, a balanced diet and consistent exercise are far more effective. For those seeking quick fixes, understanding the limitations is essential.

Conclusion: Navigating Coffee on a Restrictive Plan
For those determined to follow the cabbage soup diet, a cup of plain, black coffee can offer a familiar comfort and a caffeine boost without breaking the rules. However, the decision should be made with a clear understanding of the diet's limitations and potential side effects, including the risk of dehydration and nutrient deficiencies. It's a short-term solution that requires strict adherence, and the health-conscious approach is always to prioritize a balanced, sustainable nutrition plan over a restrictive fad diet.
Note: The cabbage soup diet is not recommended by most health professionals for sustainable weight loss. Consult with a doctor or registered dietitian before beginning any new diet plan, especially if you have underlying health conditions like diabetes.
