Most people see a 2–10 lb drop in week one, driven by water loss and lower calories; staying on it longer can backfire.
The cabbage diet (often the “cabbage soup diet”) is a short, strict plan built around cabbage soup plus a narrow list of add-on foods by day.
What The Scale Drop Usually Means
Most quick-loss diets share the same pattern. The first few days cut total food volume, carbs, and salt. That combo drains stored glycogen and the water that sits with it. Your gut also holds less food weight when meals get repetitive and low in energy density.
So if you step on the scale on day 7 and you’re down 6 lb, don’t assume you burned 6 lb of fat. Think of it as a mix: water, gut content, and some fat. That framing keeps expectations grounded and keeps you from chasing extremes.
How Fast Loss Compares With Standard Guidance
Public guidance on weight loss pace is plain: slow and steady tends to stick better. The CDC notes that people who lose weight at a gradual pace of about 1 to 2 pounds per week are more likely to keep it off. CDC guidance on losing weight frames this as a better long-run pattern than racing the scale.
The cabbage diet can beat that pace on paper for one week. Past that, you run into practical limits: hunger, boredom, low protein, and gaps in micronutrients. Those limits raise the odds of cravings, late-night snacking, and a swing back up on the scale once normal meals return.
How Much Weight Can You Lose On The Cabbage Diet? With Realistic Numbers
Here’s what people often report, broken into ranges that match how the plan is usually done: one tight week, then a return to normal eating. Your results can swing based on starting weight, the exact soup recipe, how much fruit or starch shows up on the “allowed” days, and whether you keep moving.
Use these ranges as guardrails, not promises. If your week includes restaurant meals, sugary drinks, alcohol, or frequent “cheat” bites, your numbers can land lower. If you start with a higher body weight and you cut carbs hard, your first-week water shift can land higher.
Why The Cabbage Diet Feels So Effective
Low Energy Density Adds Up
Cabbage soup is bulky. You can eat a large bowl for not many calories, especially if the recipe is built on vegetables, broth, tomatoes, and herbs. That helps many people stay in a calorie gap without feeling like they’re nibbling on nothing.
Carb Cuts Shift Water Fast
Many versions of the plan keep starches low for several days. Lower carbs can mean less stored glycogen, and that stored glycogen holds water. That water leaves first, so the scale drops even before much fat can be burned.
Where The Cabbage Diet Can Go Wrong
Low Protein Can Cost You Lean Mass
If your week has soup, fruit, and a couple of meat days, protein may still land low for many adults. When protein and resistance training are low, some weight loss can come from lean tissue, not just fat. That can slow resting energy burn later and can leave you feeling flat and hungry.
Low Calories Need Medical Guardrails For Some People
Some cabbage diet weeks drift toward the “under-800-calorie” range. The NIH’s National Heart, Lung, and Blood Institute notes that diets under 800 calories per day shouldn’t be used routinely and can require doctor monitoring. NHLBI “Aim for Healthy Weight” (PDF) includes this warning in plain language.
If you are pregnant, breastfeeding, under 18, managing diabetes, dealing with kidney disease, or taking medicines that change appetite or blood pressure, don’t treat a cabbage week as a harmless reset. A short “diet week” can still trigger low blood sugar, dizziness, or swings in blood pressure in some bodies.
Sodium And Broth Choices Can Flip Results
Many recipes rely on packaged broth, bouillon, or canned tomatoes. Those can drive sodium up. A high-sodium soup can keep water on board, so the scale drop looks smaller. It can also leave you thirstier, which some people misread as hunger.
Monotony Can Trigger A Hard Rebound
When a plan is rigid, the “off switch” can break. People white-knuckle a week, then feel done with rules, then eat past fullness. If that pattern sounds familiar, treat the cabbage plan as a one-week experiment, then switch to a steadier setup.
Table: Typical Week-One Changes On A Cabbage Soup Style Plan
| Scenario | Scale Change You Might See | What Drives It |
|---|---|---|
| Strict 7-day run, no extras | 4–10 lb down | Big water shift + lower calories |
| 7 days, soup plus “allowed” foods in full portions | 2–7 lb down | Water shift with a smaller calorie gap |
| 5 days, then normal eating on weekend | 1–5 lb down | Early drop, then partial rebound |
| Low-salt soup, high water intake | 3–9 lb down | More water loss from lower sodium |
| High-salt soup, deli meats, canned broth | 0–5 lb down | Water retention offsets the gap |
| Higher starting weight, big carb cut | 5–12 lb down | Larger glycogen and water drawdown |
| Lower starting weight, active job, low sleep | 1–6 lb down | Smaller water shift; appetite fights back |
| Constipation or low fiber variety | Scale may stall | Gut content masks fat loss |
If you want a steady pace after the week, start from a simple anchor: the CDC points to gradual loss of about 1–2 lb per week as a pattern that tends to stick. CDC steps for losing weight spells out that expectation.
You’ll notice the table mixes “down” outcomes with stalls. That’s real life. The cabbage plan can also cause bloating in some people, since cruciferous vegetables can raise gas. That can hide scale change for a few days.
How To Track Fat Loss Without Losing Your Mind
A weekly weigh-in after a strict diet can be noisy. Water and gut shifts can make you feel like you failed even when you didn’t. Use a simple routine instead.
- Weigh at the same time of day, after the bathroom, before food.
- Watch a 7-day trend, not one reading.
- Jot down sleep and stress; both can shift hunger and water.

How To Eat During The Week So You Don’t Feel Wrecked
Build The Soup Like A Meal, Not A Punishment
Many recipes are bland because people fear calories from flavor. You can keep the soup low-calorie and still make it satisfying with garlic, onions, celery, herbs, pepper, chili flakes, vinegar, and lemon. If you can handle heat, spice can slow down how fast you eat.
If you’re adjusting the soup recipe, keep the numbers grounded by checking a standard nutrition listing. USDA FoodData Central cabbage nutrients is a straight source for calories, fiber, and vitamins.
Add Protein Where The Plan Allows It
On meat or dairy days, pick lean protein and keep portions steady: chicken, fish, eggs, tofu, low-fat yogurt, or beans if your version allows it. That helps with fullness and keeps muscle loss lower.
Don’t Let “Unlimited Soup” Turn Into A Gut Problem
Some people can eat cabbage all day and feel fine. Others get cramps and gas. If that’s you, cap soup bowls, chew slower, and rotate in the allowed foods instead of forcing more cabbage.
What Happens After Day Seven
This is where most of the real outcome is decided. If you return to your old pattern, the scale tends to rebound as water returns and food variety comes back. That doesn’t mean the week was “fake.” It means the early drop had a water chunk.
Plan for the next 10 days before you start the diet week. If you already know what breakfast and lunch will be after day seven, you avoid the “free-for-all” feeling.
Table: A 10-Day Step-Down Plan After A Cabbage Diet Week
| Day Range | What To Add Back | Goal |
|---|---|---|
| Days 1–2 | Regular breakfast with protein + fruit | Stabilize hunger |
| Days 3–4 | Starch at one meal (rice, oats, potato) | Reduce cravings |
| Days 5–6 | Two balanced meals + one planned snack | Stop grazing |
| Days 7–8 | Strength training 2 sessions this week | Protect muscle |
| Days 9–10 | Keep soup as a side, not the main | Make the pattern livable |
During this step-down, expect the scale to rise a bit. That’s normal water and glycogen returning. If you keep portions steady and protein present, the longer-run trend can still move down.
So What’s A Realistic Outcome You Can Keep?
If you do one cabbage week and then shift into a steady calorie gap, the lasting part often looks like this: you keep 1–4 lb of the week-one drop after two weeks, then you lose at a slower pace after that. The cabbage week can be a motivator, but the keeper weight comes from habits you can repeat: protein at each meal, fiber from plants, planned treats, and movement you don’t dread.
Red Flags That Mean Stop And Check In With A Clinician
Some signals mean the plan isn’t a fit for you right now. Stop the diet week and talk with a clinician if you notice fainting, chest pain, confusion, persistent vomiting, black stools, or blood sugar lows. If you have diabetes, heart disease, an eating disorder history, or you take insulin or diuretics, a strict low-calorie week needs medical input first.
One last note: the cabbage plan is a short-term tactic, not a long-term way to eat. If you treat it as a week-long reset, then you roll into a steady pattern with enough protein, sleep, and activity, the result can be progress you can keep.
