What Is the Cabbage Soup Diet? Foods, Rules, Risks & Alternatives
Risk band: Restrictive · Reviewed
The cabbage soup diet is a short fad pattern built around a vegetable soup, usually for about seven days. Forwarded copies promise a fast drop on the scale. The soup is ordinary food. The week wrapped around it is a crash diet: very little energy, very little variety, and a menu that changes by slogan rather than by need.
Restrictive risk band. Explaining the cabbage soup diet is not an endorsement. This page describes the pattern so the rules and the harms sit in one place. It does not give a menu, a recipe with amounts, or a calorie target to follow.
Disclaimer
Educational only. Not medical advice. A week of cabbage soup is not a treatment for weight, blood pressure, cholesterol, diabetes, or any other condition. It can be unsafe in pregnancy, in childhood, with many medicines, and with a history of disordered eating or serious illness. Consult a qualified clinician before you change how you eat, and a registered dietitian nutritionist (RDN) when you want help planning ordinary meals. No results are guaranteed.
Quick facts
| What it is | A short fad diet, usually framed as seven days, centered on a repeated vegetable soup |
| Risk band | Restrictive — strong caution; explain ≠ endorse |
| Also circulated as | Sacred Heart diet and other hospital-named copies; those names are not a clinical protocol |
| Not the same as | A bowl of cabbage soup inside a normal meal, or the published Mayo Clinic Diet |
| What the rules drop | Mixed meals, steady protein, and most grains, fats, and dairy for much of the week |
| Why the scale moves | Mostly water and stored carbohydrate, plus less food in the gut |
| Safer baseline | A balanced plate that can include soup without a seven-day script |
What the cabbage soup diet is
People mean a crash pattern, not the vegetable. Since the 1980s, copies have told people to repeat one pot of soup and to allow almost everything else only on a named day.
Those copies traveled by chain letter, fax, and the internet, and they picked up famous labels: Sacred Heart, other hospitals, the American Heart Association, and sometimes the Mayo Clinic. Several named hospitals, and the American Heart Association, have said they did not create this plan and do not endorse it. A name on a forwarded sheet is not a cardiac program. The published Mayo Clinic Diet is a separate pattern. Some “Sacred Heart” copies change the soup and still keep the same seven-day restriction. There is no official menu.
A bowl of cabbage soup next to beans, rice, fish, or chicken is ordinary cooking. The diet is the decision to let the soup replace most of a week’s food.
How it works
Public versions share a shape. For about seven days the soup is the food you are told to repeat freely, and each day adds only a small set of other foods. Across the week those extras are usually fruit, non-starchy vegetables, bananas, milk, a plain meat such as beef, and rice — not all on the same day. A potato, a little butter, or unsweetened juice shows up in some copies only. Fat, mixed dishes, and a steady protein source stay scarce.
This page does not print the day order, soup amounts, or a start-on-Monday schedule. That calendar is a crash plan. The shape is enough: one food treated as endless, and the rest of the plate split into isolated days.
Fruit-and-vegetable days are very low in energy and protein. A bananas-and-milk day is a different narrow menu. A day that adds meat or rice is less empty and still not a balanced plate. Copies disagree, so this page quotes no calorie figure. Many versions still sit in very-low-calorie territory. Clinics that use intakes that low add screening, labs, and supervision.
Why the scale can drop in days
Forwarded plans often promise a loss on the order of ten pounds in a week. A change that large, that fast, is mostly water. Glycogen holds water; when carbohydrate intake collapses, both fall. A lower-sodium week and less food in the gut move the scale too. Seven days is too short for that number to match fat loss, and the water returns with ordinary meals.
Cabbage does not make the drop special. Many vegetable soups are low in calories for their volume. The pot does not burn fat or “detox” anything. The liver and kidneys already handle waste.
The week practices a closed script, not grocery meals you can cook with other people. When it ends, the scale often moves back. Repeating it stacks the same costs. The short sprint is how the fad is sold.
Foods commonly included and left out
Lists below describe common copies. They are not a medical order and not a recipe. Amounts and “eat all you want” instructions are left out.
Often named in the soup: cabbage, onion, celery, bell pepper, tomato or tomato juice, broth or bouillon, and seasonings. Some copies add a packaged onion-soup mix.
Often allowed somewhere in the week, not together: the soup; fruit, with bananas held off some days; other non-starchy vegetables; bananas and milk, often skim, paired on one day of the lore; a plain meat such as beef, sometimes with tomatoes; rice, often brown, near the end of some versions. A potato, a little butter, or unsweetened juice appears only in scattered copies.
Often missing for most of the week: mixed meals; eggs, fish, beans, nuts, yogurt, and cheese as a steady pattern; bread and other grains aside from that occasional rice; added fats in any reliable amount; sauces and cultural dishes that do not match the day’s slogan.
A day inside this pattern is repeated bowls of the same soup, plus one allowed category. Eggs and toast, a lunch with protein and a grain, and a mixed dinner are the meals the rules remove. That gap is the diet. Cabbage and tomatoes are useful on a varied plate; a week that serves them almost alone wastes that.
Potential benefits
People try this pattern because the script is short and the soup is cheap. Those wants are real. They are not a result, and they are not a reason to start.
A closed week. Fewer decisions can feel like relief. That feeling says nothing about fit with your health or your medicines.
A low-cost pot. Cabbage, onion, celery, and canned tomato are inexpensive in many stores. The price favors the ingredients, not a week of eating little else.
Soup kept as soup. One bowl fits a balanced plate without a seven-day ban on the rest of the kitchen.
An early scale change. Some adults weigh less after a few days because of water and glycogen. That is a poor measure of fat loss.
Lasting benefits are not established. Major clinical guidelines do not list this diet for weight, blood pressure, blood sugar, or cholesterol. This draft invents no trial. Any large energy deficit can move weight for a while. The soup’s name adds no special effect.
Risks & who should avoid
Restrictive is the right label. The week drops foods that usually supply protein, essential fats, and a wide set of vitamins and minerals. Harms follow from that design even when the script is short.
A crash week can bring fatigue, headache, irritability, feeling cold, trouble concentrating, and dizziness. A sudden volume of cabbage often causes gas, bloating, or diarrhea. Protein is scarce on most days, a poor match for growth, pregnancy, older age, or keeping muscle, and essential fats, calcium, iron, and vitamin B12 are easy to miss. Rapid loss is a known setting for gallstones. Hunger often rebounds when the rules end.
Seek urgent care for chest pain, fainting, confusion, vomiting that will not stop, or a rapid or irregular heartbeat. If you already live with an illness and you feel worn down, stop and call a clinician.
Diabetes medicines. Insulin and other glucose-lowering drugs can cause low blood sugar when meals shrink this fast. Only the prescriber changes a dose.
Blood pressure medicines and diuretics. Less food, less sodium, and a quick water shift can mean dizziness or pressure that runs too low.
Warfarin and related anticoagulants. Cabbage contains vitamin K. A sudden large amount can matter for people on warfarin. The clinician who checks your results owns that conversation.
Kidneys, gout, and gallbladder disease. Kidney diets are individualized. Rapid loss can provoke gout in people who already flare, and existing gallbladder disease is a reason to skip a crash week.
Pregnancy, breastfeeding, childhood, and adolescence. Needs are higher. This pattern does not belong in those years or in pregnancy.
Eating disorders. A banned list and a seven-day clock can worsen disordered eating. That history belongs with a clinician first.
Training, frailty, and low body weight. Hard exercise on this intake is under-fueling. Frail and underweight adults can lose strength quickly.
Packaged broths often contain wheat, milk, soy, or a high sodium load. Pairing the week with fasting deepens the harm. Talk with a clinician before any version if pregnancy, growth, disordered eating, glucose-lowering drugs, warfarin, blood pressure drugs, kidney disease, gout, gallbladder disease, frailty, or low body weight is in the picture. If you already started and feel unwell, stop and get advice.
Safer alternatives
A steadier weight, or simply more vegetables, does not require a seven-day soup script.
- Balanced plate. Vegetables and fruit, protein, and satisfying carbohydrates, with fats in a supporting role. Cabbage can be one vegetable on that plate.
- Mediterranean diet. Vegetables, fruit, legumes, whole grains, olive oil, and fish, with room for shared meals.
- DASH. An inclusive pattern often used in blood-pressure education, built from grocery food.
- Sustainable weight loss. Repeatable habits for people whose goal is weight, without a seven-day event.
- Soup as one dish. Cabbage, onion, tomato, and celery, served with beans or another protein and a grain. That is lunch.
The carnivore diet is another letter-C restrictive pattern, and a poor swap. Keto and Optavia sit in the same risk band. An all-animal menu, a ketosis target, or a very-low-calorie product plan narrows the plate further.
Labs, medicines, pregnancy, and disordered eating belong with an RDN and the clinician who knows your history. Very-low-calorie approaches, when they are used at all, belong under medical monitoring.
FAQ
What is the cabbage soup diet?
A fad of about seven days: repeated vegetable soup plus a short list of other foods that rotates. Copies spread by chain letter, often under hospital names those hospitals have rejected. This description is not a suggestion to start.
What can you eat on it?
Common copies use cabbage, onion, celery, pepper, and tomato, then one narrow extra — fruit, vegetables, bananas and milk, a plain meat, or rice. Steady protein and mixed meals are missing for much of the week. The day-by-day schedule is not reprinted here.
Does it work for weight loss?
The scale often drops within days because glycogen, water, and gut contents change. That is a weak stand-in for fat loss, and the water commonly returns. See the balanced plate and sustainable weight loss for a safer frame.
Is the cabbage soup diet safe?
For many people it is a poor idea, and for some it is unsafe: fatigue, dizziness, digestive upset, gallstone risk, and clashes with diabetes drugs, blood pressure drugs, and warfarin. Pregnancy, childhood, and disordered eating are reasons to stay away. A clinician judges safety for a specific person.
Is this the Mayo Clinic Diet or a hospital heart diet?
Copies borrowed those names. Named hospitals and the American Heart Association have said they did not create or endorse the plan. The published Mayo Clinic Diet is a separate program. A real pre-surgery diet comes from that person’s clinical team.
Can cabbage soup be part of a normal diet?
Yes. A bowl with protein, other vegetables, and a starch fits a balanced plate, and it fits Mediterranean and DASH meals. The harm is the week that replaces meals with soup.
Who should not try it?
Stay away if you are pregnant or breastfeeding, a child or teenager, living with disordered eating, managing diabetes with medication, taking warfarin, or living with kidney disease, gallbladder disease, or gout. Frailty and low body weight call for a plan that feeds you. Ask a qualified clinician when you are unsure.
