What Is the Purium Diet?

Verywell / Debbie Burkoff

At Verywell, we believe there is no one-size-fits-all approach to a healthy lifestyle. Successful eating plans need to be individualized and take the whole person into consideration. Prior to starting a new diet plan, consult with your healthcare provider or a registered dietitian, especially if you have an underlying health condition.

The Purium 10-Day Transformation is a cleanse that promises to increase your energy, improve sleep, reset your metabolism, and help you lose up to 11 pounds and eight inches in just 10 days. While that certainly sounds enticing, there are considerations to keep in mind before you try this plan.

Purium was founded in 1993 by David Sandoval, who is also the author of The Green Foods Bible. It is sold by Purium Health Products and he is still with the company (his title is "Co-founder and Visionary"). His biography provides no specific information about credentials in the health or wellness space. This multi-level marketing company sells shakes, supplements, powders, and other products related to diet and weight loss.

Meal replacement shakes, supplements, and minimal fruits and vegetables make up the 10-Day Transformation - Weight Loss diet. The diet is only meant to last 10 days but it isn't likely to promote lasting weight loss or teach habits that users could benefit from after the 10-day period.

What Experts Say

"The Purium Diet is a very-low-calorie 10-day plan which promises quick weight loss. It consists of just 600 calories a day, which experts warn is not healthy or sustainable. Even over just 10 days, people may experience side effects like fatigue and irritability."
Chrissy Carroll, RD, MPH

What Can You Eat?

There are three different 10-day transformation programs from which to choose: Purium 10-Day Transformation - Weight Loss, the Purium 10-Day Transformation - Cleansing, and the Purium 10-Day Transformation - Athletes. This diet is similar to the GOLO Diet.

If you take on the Purium program for weight loss, you can expect to consume three shakes a day, supplements every few hours, and a tart-cherry drink at the end of the day. The plan also allows for small portions of "flex foods." You may drink up to 72 ounces of water daily, along with some other approved beverages.

What You Need to Know

The meal replacement shakes and supplements are spread out at two-hour intervals. Here's how a day would look if you rose at 7 a.m. Flex foods or beverages can be consumed at any three of these intervals.

  • 7 a.m.: Super Amino 23, Super Lytes, and water
  • 9 a.m.: Power Shake
  • 11 a.m.: Super Amino 23, Super Lytes, and water
  • 1 p.m.: Power Shake
  • 3 p.m.: Super Amino 23, Super Lytes, and water
  • 5 p.m.: Power Shake
  • 30–60 minutes before bed: Apothe-Cherry and Daily Fiber Blend

Fitness activities are not promoted in this plan. In fact, according to instructions, exercise should be limited to light walking and yoga. The instructions also recommend getting a good night's sleep each night while on the program.

The 10-Day Transformation - Athletes plan offers some different products and ingredients, as well as allowing one 300-calorie "lifestyle meal" for every 30 minutes of daily exercise. These meals can include whole grains and lean protein, along with fruits and vegetables.

The Weight Loss Transformation plan recommends adding an additional flex food serving, or a lifestyle meal if you feel tempted to cheat or abandon the program.

Purium offers inspirational tips by text, support-group-style phone calls, and a Facebook group for people doing these plans. All are optional.

What to Eat
  • Purium products

  • Certain fruits and vegetables

  • Certain flavorings

  • Certain beverages

What Not to Eat
  • Caffeine and alcohol

  • Meat, eggs, dairy products

  • Grains and starches

Purium Products

Each Transformation pack contains Power Shake powder, Apothe-Cherry concentrated tart cherry juice, and Super Amino 23 amino acid supplements. The Weight Loss package also includes Daily Fiber Blend powder and Super Lytes supplements.

Fruits and Vegetables

Three servings of a "flex food" or "flex beverage" are allowed per day. Flex foods include avocado, apple, watermelon, cucumbers, broccoli, cauliflower, kimchi, and summer squash. For most of these, the serving size is one cup.


Dress up your flex foods with organic tropic oil, freshly squeezed lemon, Himalayan sea salt, raw honey, or fresh herbs and spices.

Flex Beverages

These may be consumed alone or mixed with Power Shake powder, but they count toward the three daily servings of food or beverage: hemp, almond, coconut, or oat milk; kombucha; organic vegetable broth; decaffeinated herbal tea; coconut water; and Purium green drinks.

Caffeine and Alcohol

Caffeine and alcohol are not allowed on the program, and Purium recommends withdrawing from these in the days prior to starting your cleanse (three to five days prior for coffee).

Meat, Eggs, Dairy Products

The 10-Day Transformations are vegan plans and no animal products are permitted. The instructions recommend avoiding meat, dairy, and processed foods for two to three days before the 10-Day transformation period.

Grains, Starches, Other Fruits and Vegetables

Any food that isn't on the flex foods list is off-limits. That includes all grains, processed foods, and fruits and vegetables including bananas, potatoes, corn, and winter squash.

Pros and Cons

  • Structured plan

  • Short-term weight loss

  • Cost

  • Extremely low in calories

  • Does not teach healthy habits

  • Not supported by evidence-based research


Structured Plan

On this eating plan, everything is prescribed and set up for you. There are few decisions to make other than what flavor of shake you want or which flex food to eat (and even in those cases, your options are quite limited).

Short-Term Weight Loss

By limiting your calories to this degree, you are almost guaranteed to lose weight. However, it may return quickly once you go back to a regular diet. (Purium also offers 40-day programs and dozens of other dietary products and supplements.)

The quick weight loss and all-inclusive packaging of the Purium 10-Day Transformation might be appealing. But be aware of the drawbacks to this program.



Each package retails for about $249, although you can sign up for a rewards program to get discounts and earn points. While everything is organized and planned, it still amounts to about $20 a day.

Very Restrictive

The Purium 10-day cleanse for weight loss claims to activate the hormone adiponectin, burn fat, build muscle, and aid the body in detoxifying and cleansing the digestive tract.

According to Purium, its shakes and supplements flood the body with nutrient-dense, low-calorie superfoods, helping to break addictions to foods containing sugar, salt, carbohydrates, and chemicals. On a 10-Day Transformation, you'll consume about 600 calories a day.

"Diets that are less than 1200 calories per day do not provide enough energy or nutrition for the necessary, basic biological functions of an adult human,” says preventive cardiologist Yasmine Ali, MD, MSCI, FACC, FACP. “Plus, severe calorie restriction sends the body into starvation mode, which makes humans hold on to weight rather than continue to lose it. These diets usually backfire for that reason, as well as for the fact that they are simply unsustainable." 

Does Not Teach Healthy Habits

When you drink meal-replacement shakes and take supplements for the majority of your daily food intake, there is no opportunity to learn healthy eating habits, smart cooking skills, or portion control. All of these are all important to maintaining weight loss.

Not Supported by Evidence

While the program promises weight loss, detoxification, and other benefits, high-quality evidence to support these benefits is lacking. In fact, the National Institutes of Health has provided an overview to help consumers understand the potential impact of these types of programs.

In short, they explain that research is lacking but so far, there isn't enough evidence to show that these programs provide any real "detox" benefit and may only provide some limited weight loss benefits in the short term and may even lead to weight gain in the long run.

Is the Purium Diet a Healthy Choice for You?

The Purium 10-Day Transformation bears a resemblance to some other meal-replacement and low-calorie plans that promote weight loss. Much like the Purium plan, the Isagenix diet consists mostly of meal-replacement shakes and supplements. Many different products and programs are available. On the Medi-Weightloss Diet, users eat a very low-calorie, high-protein diet during the first, or "acute weight loss," phase. They also consume dietary supplements. In subsequent phases, they add in more calories and carbohydrate servings.

Current guidelines set forth by the U.S. Department of Agriculture suggest eating a balanced mix of fruits, vegetables, protein, grains, and dairy products each day. Experts also note that it's better to get nutrients from foods vs. supplements. On the Purium diet, most of the protein you consume is from powdered shake mix and the only other solid foods you eat are fruits and vegetables.

The Purium plan is much lower in calories than the USDA's recommendation of 1,600–2,400 calories a day for females and 2,200–3,200 calories per day for males. Since daily calorie needs vary significantly depending on your age, sex, and activity level, you can use this calculator to determine a goal that's right for you.

Although it may claim to offer complete nutrition, the Purium plan does not meet expert advice for healthy eating.

A Word From Verywell

Most health experts agree that "detox" programs for weight loss that eliminate entire food groups or severely restrict your calorie intake are generally not successful for long-term health or weight loss. Many of these programs are not backed by scientific evidence and can be dangerous to health, contradicting the benefit that they propose to provide. These programs are generally best followed while under the care of a health care provider.

If your goal is weight loss, consider making an appointment with a registered dietitian to put together a plan for sustained, healthy weight loss. Both your body and your budget are likely to benefit from a more conservative approach.

Remember, following a long-term or short-term diet may not be necessary for you and many diets out there simply don’t work, especially long-term. While we do not endorse fad diet trends or unsustainable weight loss methods, we present the facts so you can make an informed decision that works best for your nutritional needs, genetic blueprint, budget, and goals.

If your goal is weight loss, remember that losing weight isn’t necessarily the same as being your healthiest self, and there are many other ways to pursue health. Exercise, sleep, and other lifestyle factors also play a major role in your overall health. The best diet is always the one that is balanced and fits your lifestyle.
