Key Takeaways
- Fat Flush Cran-Water is Ann Louise Gittleman’s signature daily beverage from the Fat Flush program: 1 oz pure unsweetened cranberry juice mixed with 7 oz filtered water.
- The organic acids in cranberry (malic, citric, quinic) are believed to help emulsify stagnant lymphatic waste—the system Ann Louise calls the body’s “garbage collector”—which many Fat Flushers link to reduced cellulite and water retention.
- It supports the liver’s detox pathways so the organ can more effectively process fats rather than store them.
- Cranberries are high in polyphenols and antioxidants (historically ranked among the highest ORAC fruits); they also help with blood-sugar balance and hydration.
- Rapid early weight drops (sometimes 6–7 lbs in a day) are typically water weight from reduced bloating; lasting benefits come from consistent use within a liver-supporting plan.
If you’ve ever looked in the mirror and felt frustrated by stubborn dimpling on your thighs, afternoon bloat that makes your clothes feel tighter, or the sense that your body is holding onto water and toxins no matter how carefully you eat, you’re not alone. I’ve heard this from women for decades—and it’s one of the reasons I created my signature Fat Flush Cran-Water.
In my clinical work and through the millions of people who have followed the Fat Flush program, I’ve seen the same pattern: a liver that’s overloaded can’t efficiently process fat, and a sluggish lymphatic system lets waste and fluid accumulate under the skin. The result often shows up as cellulite, puffiness, and stalled progress. My simple cran-water became the daily tool that helps keep those pathways moving.
Why Cran-Water Is the MVP of Fat Flush
The Fat Flush approach is built around supporting the liver as the body’s primary purifier. When the liver is congested with excess fats or toxins, it can’t fully perform its fat-metabolizing role. Cran-Water—made with antioxidant- and polyphenol-rich unsweetened cranberry juice—helps keep the liver’s detox pathways active while addressing the lymphatic system.
Cranberry juice contains flavonoids, enzymes, and organic acids (including malic, citric, and quinic acids) that appear to have an emulsifying effect on stubborn deposits in the lymph. The lymphatic system transports waste products the liver doesn’t process. When those wastes stagnate, they can contribute to the dimpled appearance many of us know as cellulite. From the feedback I’ve received over the years, this is why so many Fat Flushers report smoother-looking skin once they make cran-water a habit.
Even if you’re not following a full Fat Flush plan or actively trying to lose weight, sipping this tart, refreshing drink daily can help reduce water retention, support blood-sugar balance, and keep your liver and lymph in a healthier cleansing mode. Some people have reported dropping as much as 6 to 7 pounds of backed-up fluid in the first day—primarily water weight from reduced bloating.
The Original Fat Flush Cran-Water Recipe
Per 8-oz serving:
Mix 1 oz of 100% pure unsweetened cranberry juice with 7 oz of plain filtered water.
Full-day batch (64 oz / 8 servings):
Add 1 cup (8 oz) unsweetened cranberry juice to a half-gallon container and fill the rest with filtered water. Mix in the morning and sip throughout the day.
Important: Use only 100% pure unsweetened cranberry juice—not a cocktail or blend sweetened with sugar, high-fructose corn syrup, or other juices. The tart flavor is part of what makes it effective.
Additional Benefits of Cranberry
Beyond its role in the Fat Flush program, cranberries offer broader support:
- They rank among the highest antioxidant fruits (historically cited with an ORAC value around 9,584 for the whole fruit, higher than many other berries). Their polyphenols help neutralize free radicals.
- Research has explored cranberry’s potential to support healthy cholesterol markers, including HDL (“good”) cholesterol.
- The same compounds that benefit the urinary tract and oral health can help limit certain bacterial biofilms.
- Just a small amount delivers a concentrated dose of polyphenols—far more than many other common fruit juices.
Putting It Into Practice
You can enjoy cran-water on its own or use it as the liquid base for smoothies. Many people combine it with clean protein such as Fat Flush Body Protein for a more complete, satisfying drink that supports blood-sugar balance and satiety.
For the full context of how cran-water fits into a liver-focused eating plan—including menus, the role of friendly fats, and strategies for lasting results—see my updated book The New Fat Flush Plan. You can also explore more resources at fatflush.com.
The Bottom Line
Fat Flush Cran-Water is a simple, inexpensive daily habit that supports the liver and lymphatic system—the two systems I have long considered central to metabolic health, fluid balance, and the appearance of skin. It won’t replace a balanced diet or overall lifestyle, but for generations of Fat Flushers it has been the quiet daily tool that helps reduce bloating, support detox pathways, and contribute to smoother-looking skin.
Start with the basic recipe, sip it consistently, and notice how you feel. Your liver—and your lymph—will thank you.

I love the FF diet, however, I find that after drinking cranwater for a week, I get little cankers inside my mouth,especially when I have strawberries too. Is this crazy? What can I do? I need to do my FF in Sept(I do a 2 week cleanse spring and fall.
I have the same problem with the acid bothering my mouth.
Does this combination really, truly help remove cellulite? If so, please help me figure out a way to drink it without it irritating my mouth. I’m desperate!
Thank you!
You can always drink the cranwater through a straw, which can help if you are sensitive to it. Also you can drink some plain filtered water afterwards if you really have a problem.
While cranberry has the most benefits, some people to have a sensitivy or allergy and so could use apple cider vinegar instead. Use 2 Tbs acv per quart of filtered water, Another option is pomegrante water, 2 oz of pom juice per 30 oz of filtered water.
This is a very old discussion, but I’m looking for answers too. I developed a canker sore as well after two days of drinking the cran-water. I was thinking, though, that the sore is a sign of detoxing. When I’ve had reactions like this in the past using homeopathy I was told that. Any truth to this?
Is it Ok to add stevia to the cranwatrer?
I add 4 pkts of stevia (equal to 8 tsps of sugar) to 64 oz of cranwater.
I do not know if the stevia hinders the cranwater’s effect on the liver
Ladies: Dilute the cranwater as much as possible – and omit other acidic elements from the plan in the meantime (this includes strawberries and lemon water). The cranwater targets the lympth with cranberriy’s four organic acids that function as fat busting digestive enzymes. While the apple cider and vinegar can help with weight loss it is not as effective when it comes to cellulite.
Stevia may change the beneficial pH of the Fat Flushing cranwater. So — less is more. Four packets of stevia plus is way too much in one quart of one water. One should more than suffice for each quart 🙂
Hi – this is an unrelated question (sorry). I am doing the fast track detox and I find myself skipping lunch and sometimes a snack. How important is it to eat everything? Am I setting myself up for failure? I am just finishing day 3. Also is this safe for a teen to do?
Thank you so much
Jenny
I currently drink a morning smoothy w/ 1C apox of cran juice. Am wondering is there any benefit to drinking it thru-out the day in the cran-water? besides the obvious of being hydrated?
Yes, I read the benefits listed above. But what I’m wondering is all-at-once vrs thru-out-the-day (for the cran benefits).
thanks
Jenny – don’t sweat an occasional missed meal, just try to eat a little something every four hours or so. YES — perfectly safe for teens and tweens and in-betweens!
Helen: Best to drink the cran throughout the day rather than concentrate it for the smoothie as throughout the day gently but effectively cleanses the lympth at a rate the body can deal with most effectively 🙂
Thanks for your queries and your interest in ALG’s programs and products!
Thank you so much!
I have suggested to my 25 year old daughter that she drink the Long Life Cocktail and warm lemon water each day. She has been dealing with acid reflux in just the past year and is changing her diet. Will either of these drinks, considering they are diluted, affect her negatively? Or, can she drink them without worrying about side effects of the acid in them? She is also a vocalist and her vocal cords have been inflamed from the acid reflux in the last year. She actually didn’t realize she had the acid reflux until a dentist noticed the effects on her teeth. She is working with a medical professional, a vocal specialist and also is vocal director for high school so has to talk/sing all day during the school year.
I read your book, the Fat Flush Plan, at least 3 years ago and have been diligently drinking the cocktail and the warm lemon water. I also was told around that same time that I may have a little arthritis around my sternum; the lymph nodes were slightly enlarged and I felt a bit uncomfortable at times. Not real pain, just like I’d slept in an awkward position. Needless to say, after a short time of drinking daily what you have recommended, I no longer felt any discomfort. I’ve felt good to this day.
I’ve been fortunate not to have any major health problems and continue to try to incorporate your wealth of information into my life. I’m not perfect, but continue to do the best I can and I encourage my daughter. I plan to incorporate the whey protein product, also.
I want my family to feel as good as I do, so will continue to pass on your information. So much to learn! Thank you for your advice; it’s appreciated.
I was drinking the cran-water and doing the fat flush and everything was going well. Maybe for a month and then I started coughing. I had to go on antibiotics and when that didn’t work then steroids and inhalers. When all that failed I went to an ENT who wasn’t sure what I had but she thought I might have acid reflux. I had to go on a steroidal inhaler which seemed to work in conjuction with anti reflux meds which I used for a short while. I stopped drinking the cran water. Basically it’s 6-8 weeks later and I am no longer coughing. I have gained weight and every time I start drinking the cranwater again which I love I start coughing the next day. I am suspecting that the cran water is causing the cough. Perhaps its too acidic for me? Have you heard of this before?
What should I use instead?
Sorry to hear about your cough. Perhaps you have an allergy to the cranberries, which is rare.
Instead, you can use 2 Tbs of apple cider vinegar to 1 qt. of filtered water or 2 oz of pure pomegrante juice in 30 oz of filtered water.
Hello,
I’m also curious about the cranberry drink’s effect on a stomach with acid reflux.
I drank acv diluted in water to help detox, etc. (supposedly would help heel reflux) but I’ve noticed it’s only made it worse, along with my coughing that I assume is from the worsening of the reflux. With that said, I’m hesitant to try the cranberry, scared it will do the same thing.
Any help? Maybe dilute it more than the recommendation?
Thanks!
Yes you could double the dilution and see if that works for you. Ann Louise has recommended taking HCL+2, to help with reflux. Also taking melatonin can help with that problem.

Can I drink regular filtered water throughout the day with the ff diet? Along with the cranberry water? If so is it limited? I looked for it in the book but only saw to prepare for the two week flush to start driniking water….. I drink a rediculous amount of water round the clock normally and am not sure I can only drink 32oz in a day with the cranberry juice if I cant have more then that to drink…..Feel like I am dehydrating if I go for an hour or so without a large a cup of something to drink normally just filtered water…. thank you !!
Sharon, you should have a total of 8 ounces of pure unsweetened cranberry juice daily, and enough ounces of water to equal half of your body weight in pounds. So, however you would like to combine those will be just fine!
Is Ocean Spray 100% cranberry juice a good choice. After looking at the nutritional information it says it is really a mixture of cranberry, grape and apple juice. I don’t know how they get away with calling it 100% cranberry. It does contain 4 Weight Watcher points so is there a better option out there?
Knudsen’s makes a 100% cranberry juice. You don’t want other juices. You may need to find this at the health food store.
I just started this cleanse but started getting bad headaches/migraines which led to vomiting and diarrhea. I have no energy to do anything but when I called the Naturepath who put me on it, he said that is just my body ridding itself of the toxins. I don’t smoke, drink alcohol or coffee. Just one cup of black tea in the mornings but had to give that up. I feel miserable but really want to do this. Will it get better as I can’t afford to be sick as I have three kids and I can’t even get up from the headache.
What cleanse are you following? As with any detox protocol, the first few days can be a little rough for some. It is important to honor this process in your body- get plenty of rest, stay hydrated, and do some like stretching to help move the toxins out. I would even recommend a salt and soda bath to expedite the process. I hope you feel better soon!
Id love to know what type of cleanse youre in and the specific instructions. Could you pleade share?
RR…I had headaches the 1st time that were really severe and lasted 6 days. Then they were gone for good. I found out that I am highly intolerant to wheat and gluten thanks to the Fat Flush Plan. I had a 5 yr sinus long sinus infection. It was so bad that they started to spontaneously drain and the pain was so bad I was on prescription pain medicine. I just went back to the cran water and hot water with lemon after getting lazy and I have found that my reflux is coming back. I didn’t have it the 1st time. What do I do? I already drink apple cider vinegar in the morning? I actually like the cran water and don’t want to give it up!
Have the hot lemon water first thing in the morning, but then try spacing everything else apart, so you are not being overloaded at once!
Can children drink the cran-water
Yes, children can certainly enjoy the cran water. If it is a regular occurrence, have them drink it with a straw in order to protect the enamel of their teeth from the acidic juice.
I just began the cran water flush and after reading the comments, I am very nervous because I just started gerting acid reflux and I am not interested in aggravating it. Is it possible to dilute the 8oz of cranberry in 1 gallon of water seeing as it is essential to take in the 8oz of cranberry and you will be drinking lots more water?
You can dilute it as much as you like! The aim is to get 8 ounces of the pure unsweetened juice per day, so any way you’d like to accomplish that is fine, and more water is definitely better.
I see you have mentioned that I can sub pomegranate juice for cranberry juice if I am sensitive to the cran juice (which I seem to be). Is the cran juice more effective for helping flush fat (especially cellulite) than the pom juice? I mean, I would gladly stay with the cran juice and just dilute it a little more if it’s the most effective juice of the two. Thanks!
The cranberry juice definitely seems to be more effective in reducing cellulite. The pom juice is very high in antioxidants, but does not have the fat-busting qualities that cranberry does.
These are the ingredients in the cranberry I bought…is this the right kind to use in the cran-water? Thanks!!
Ingredients
FILTERED WATER (SUFFICIENT TO RECONSTITUTE), CRANBERRY JUICE CONCENTRATE.
Yes, that will do nicely.
I have aquestion I am new to this cranberry water drink and I was wondering if I can eat on it and if so what is allowed and what is not?
You will find a very thorough explanation of the dietary guidelines in the Fat Flush Plan book by Ann Louise Gittleman
Hi. Can I use artificial sweetener w/it? Also how much should I drink a day?
Thanks
Lisa
The Fat Flush Cran-water is best enjoyed unsweetened. Artificial sweeteners are strongly advised against.
Thank you. How much should I drink a day???
Aim for a total water intake of one half your body weight in ounces. Caffeinated or sweetened beverages do not count towards this total, but cran-water, lemon water, and dandelion root tea all count towards your daily water intake.
Thank you. I usually drink 5-6 bottles of water a day. How much fat flush water should I drink
You’ll want to aim for 64 ounces a day of the cran-water, but a total water intake of half of your body weight in ounces of water. For example, someone who is 150 pounds would need 75 ounces of water total, so 64 ounces of cran-water and 11 ounces of plain filtered water.
Oh! Ignore my post for 5/12/16. I didn’t see this one till now. Thanks!
Hello,
I’ve just made cranberry juice using fresh cranberries following the recipe in the Fat Flush Plan Book. Should I then dilute it as I do with the store bought cranberry juice?
Thanks for you answer on this.
Rhea.
Hi Rhea! Yes, you would treat your prepared juice just the same as store-bought in terms of dilution. Great time of year to make your own- ’tis the season for fresh cranberries!
Does the cranwater make your body more acidic?
No, it actually helps to alkalize your body!
All that I read says that cranberries are very acid and also acid-forming. ALG team states that it is alkaline-forming. Can you point us toward any studies which will indicate this? Working around GERD with killer heartburn.
I am accustomed to a high water intake and am wondering if I can add more filtered water than half my weight. What might the consequences be?
You may! Please be aware the too much water in a shorter period of time can deplete your minerals and cause ‘water toxicity’. But, if you feel good and are enjoying and craving the extra water, you will be fine.
Can I drink the cranberry water while brestfeeding?
Yes drinking cranwater is not a problem when you are breastfeeding.
I’ve been on the FF for 6 days now and my lower back started hurting last night. I realized this am when I woke and tried to stretch it out that I could barely bend down to touch my toes. I felt the tightness down the back of my legs. I’ve always been pretty limber and could always touch my toes. What could be the cause of this and has anyone else experienced it?
You are probably detoxing. As the toxins are released from the fat cells and travel through your lymph you can feel stiffness. This will pass in a few days, depending on your level of toxicity. Just keep doing all the elements of the program and you will get great results!
How long do you drink the cranberry mixture for. Or is it always ongoing ?
Can I drink it every other week?
You can drink it as much as you want to get the benefits.
I have type 2 diabetes(all my life) genetic, and take insulin. i have about 30 pounds to lose . I have been mixing the suggested amount of cranberry concentrate with water. I an experiencing high blood sugar after drinking. Any suggestions? Would the cranberry juice be a better choice,or using less of the concentrate/and or cranberry juice in the mix?? I use only the sugar free,pure cranberry concentrate/juice ……… Thanks
Can I drink more than 8 cup of it a day or should I have water after the 8 cups of cran wate?
Hi i am starting the parasite cleanse today and was wondering if i can/should drink cranwater or is it better to wait until i finish the cleanse???
Thank you
D
D, You can start drinking the cranwater now at the beginning of the parasite cleanse.
I prefer to drink the cranberry juice straight without diluting it. Is this ok to do this as long as I still get in enough water throughout the day and also drink the cranberry juice a couple times throughout the day to ensure that I am getting it more than just once a day?
Cranberry juice will make you very acidic when it is not diluted. Also drinking the water at the same time helps the detox. You want to follow the recipe to get the results.
I purchased pure cranberry concentrate. Do you know the juice to water ratio I should use?
If so the info will be appreciated.
Thank you
Marilyn, Use 1 1/2 tablespoons of cranberry concentrate with 32 oz of filtered water.
When do you get to eat grapes?
Grapes aren’t on the plan because they are higher on the glycemic index. You can enjoy many fruits that are lower including berries.
Hi,
I am searching for Stevia Plus. Would you be able to provide me with a specific brand? Also, is the name “Stevia Plus”?
Thank you,

Tara, here is the brand that Ann Louise recommends and the link to read more about it and order it if you wish. https://www.unikeyhealth.com/sweetleaf-stevia
Hi,
what volume or weight of cranberries will equate to 1oz of pure juice?*
If one just ate the same amount of cranberries then drank the required amount of water, will it equate to cranwater in my stomach? **
Also will warming it for 30seconds in a microwave reduce the benefits?***
Thank you very much for all the books & guidance for the past one and a half decades.
* I keep falling off the fat flush wagon & one of the many reasons (excuses:) is that pure unsweetened cranberry juice is not always available in Waitakere City, New Zealand. However frozen cranberries are. So, I pureed them to make the cranwater but I am now sure 8oz volume of cranberries does not equal 8oz of cranberry juice.
** This will save time spent on cleaning & putting away the blender etc.. Lack of time & energy are other excuses/reasons I fall off the wagon. I very badly need to get on it as my fatty liver is worsening & my weight increasing despite being a vegetarian teetotaller.
***prefer warm drinks in cold damp weather with no central heating.
how long before you see results? i started drinking cranberry juice two weeks ago but not mixed with water
Team ALG here: It’s very important that you’re drinking 100% pure unsweetened cranberry juice with 7 oz. plain filtered water. We also recommend that you follow the full Fat Flush program.
Betty, Usually people see results within 2 weeks. You want to dilute it with water for best cleansing results. Drinking it straight can make you too acidic.
The fat flush lemon water has an optional ingredient of ginger. Should it be fresh ginger or is ginger powder ok ?
Susan, Fresh ginger is better but you can use ginger powder.
Is it possible for the cranberry water to cause some gastrointestinal issues as it detoxes your liver? I stared yesterday and have had some runs and slight discomfort today.
Dawn, It’s possible but most people don’t experience this.
I am trying to start the program now but there are so many option to buy cranberry juice. I have to assume I have to buy the NOT from concentrate but most have xanthan gum. Is this ok.
Kathy, You can buy the one made from concentrate. Just look for one without the xanthan gum. Knudsen’s is a good brand.
