Volumetrics Diet Review (UPDATED 2024): Don't Buy Before You Read This!

Never go hungry again, and still lose weight.

Top Rated Diets of 2024
What is it?

The Volumetrics Diet is a weight loss plan claiming to be the ultimate diet to help provide a healthier lifestyle. It’s suggested one can lose from 1 to 2 pounds of weight each week for the duration of the diet.

The basic idea behind this plan is to eat foods which have lower calories and high water content. The diet describes caloric foods as being energy dense, which should be restricted for health benefits.  The added fiber and water from the recommended foods are meant to alleviate appetite and promote health. Our review experts have ranked many diets and the number 1 for weight loss was found to be the 18Shake Diet. It combines an appetite suppressing meal replacement which satisfies for hours, and a metabolism boosting fat burning diet pill. Both have only natural ingredients without the use of preservatives, stimulants, or colors. Discover more information about the benefits of the 18Shake Diet by clicking on the link here.

Do You Know the Best Diets of 2024?

Volumetrics Diet Ingredients and Side Effects

Information about the diet is available in the official book which consists largely of recipes. It attempts to separate different foods into most to least energy dense. Here are the categories:

Category 1 (very low in density): Nonfat milk, broth based soup, and non-starchy vegetables and fruits.

• Category 2 (low-density): Starchy fruits and vegetables, breakfast cereal, low-fat meat, grains, legumes, and low-fat dishes such as spaghetti and chili

• Category 3 (medium density): Cheese, meat, pizza, French fries, bread, salad dressing, cake, and ice cream.

• Category 4 (highest density): Chips crackers chocolate candies, nuts, cookies, oil and butter.

Our review experts have compiled a list of the top ranked weight loss diets made available here.

Category 4 is advised to be eaten at a minimum, 1 and 3 are the most preferred, and category 3 is portion controlled. There are no banned foods, only recommendations as to what’s a healthier option. Foods which are water based such as soups and paste are much preferred over other kinds of foods. This is due to their filling fiber and water content which can alleviate hunger without many calories.

The diet advises to eat foods similar to what one is craving. So instead of eating chips and dip, it’s advised to eat vegetables with humus which offer the same crunch and flavor profile. This is a way to help trick the mind into thinking it’s getting what it craves.

The basic premise of the diet is to allow users to follow their own plan with limits but no restrictions on foods. This is to make it easier to diet instead of outright banning certain foods. While this is an optimized approach, it’s also not guaranteed as a way to promote weight loss. There are no limits on calories and no available support; all the effort performed has to be done on the willpower of users. This can make it impossible for some to follow this diet without overeating unhealthy foods.

This can potentially lead to yo-yo dieting, with people going from healthy eating habits to unhealthy eating.

EDITOR’S TIP: Combine this diet with a proven meal replacement such as 18 Shake for better results.

Volumetrics Diet Quality of Ingredients

There are 4 categories where different kinds of foods are separated into. Dieters are advised to eat more foods in category one, and to limit the following higher categories. While this makes it easier to know which foods are healthy, it’s common sense advice with an added benefit of it labeling foods. Many of the foods which are present in the first category include non-starchy vegetables which are already known to be the most nutritious of foods available.

There’s not enough in this diet to help ensure weight loss will occur. This is why as you’ll see in the “Customer Opinions of Volumetrics Diet”, there have been many complaints about this diet. It’s often described as a common sense diet without much available support. The issue is that there was no need to read the diet book as people say it has no new information. Eating more vegetables is good advice, but following this repeatedly without overrating or choosing higher amounts of unhealthy foods is hard and requires dedication for some.

While there is nothing wrong in the recommendations made, it’s still unlikely to help people lose weight unless they have extreme will power and reduce their overall caloric intake.

Our review experts have crafted a best of list of the weight loss diets which can be read here.

The Price and Quality of Volumetrics Diet

The official book with outlines the diet sells for $13.37 on Amazon.com. One major issue of this diet is outlined by Healthline.com:

Business of Volumetrics Diet

Customer Opinions of Volumetrics Diet

Here are some direct quotes taken from customer reviews of the Volumetrics Diet:

“I didn’t find the magic bullet, just rehashed some of the older ones”

“the only valuable suggestions of her diet is to add more fruit and veggies and to exercise more”

“Don’t be taken in by this bogus book of fabled tales promising you fast weight loss… it’s a sham”

“This book did not teach anything new 0 it was the same diet just spoken about in a different manner”

The most common issue customers who followed the diet were that it provided only basic information that they already knew. People summarized the book as saying it advises eating more vegetables exercising, and reducing calories.

Users often added how they would not have bought the book and tried the diet if they knew it wouldn’t be helpful. People still struggled with weight loss due to the lack of quality support. There were also issues with the recipes, which many found unappetizing and time consuming to make.

Those that did enjoy the diet mention that they found it interesting to categorize different kinds of foods. There were still issues however with those who found they had to really commit to notice any changes.

Conclusion - Does Volumetrics Diet Work?

The Volumetrics Diet has a simplified categorization for foods to help show which are highest in calories, and which are lowest with increased water and fiber. This can help with weight loss and it makes it easy to understand which foods are healthy. The main problem is that that there is no additional support other than recipes. Customers often mention how they read the entire book and felt that they only reread common sense dieting information. There was a clear lack of additional support for those who don’t have the extreme will power to constantly make healthy choices. There’s also a lot of dedication one has to pay in order to make home-cooked meals all the time.

Many of the food suggestion are already known to be healthy; the problem is how to maintain this diet overtime.

Our review experts have analyzed many kinds of diets and they’ve found the 18Shake Diet is the most effective overall. It combines a fat burning diet pill alongside an appetite suppressing meal replacement. They can help maximize weight loss without the use of stimulants, preservatives, colors, artificial additives fillers, or binders.

Hi guys.

After following the Volumetrics diet for a while, I can tell it’s the best diet I have ever tried. Not only did I start to lose weight but I feel like I have more energy and sleep better. Maybe it’s only auto-suggestion, but it really seems Volumetrics is working for me.

As for books, I found a few and this one is pretty great: http://www.amazon.com/dp/B00W5DN2UK.

In it you can find real people's experiences in which they talk about recipes, side-effects of this diet, its health benefits, their weight loss journey and much more. Because it's not written by some dietitian trying to make money, it's pretty convincing. The benefits of the Volumetrics diet are almost tangible when you read this stuff.

And, best of all, you can have this book for free over the next few days. I’m a little jealous now as I paid for it, but never mind. :)

Hope you will enjoy in it as much as I did.

I was glad to see loveknot's post since I am also 5' 5" and weigh 156, and her results have been very good. I am going to purchase this book within the next 48 hours and begin it. Also, it received the highest rating of all diets from consumerreports.org!

I've really been able to stick with this diet. I am a 5'5" woman, and moderately active. I started out at 156 lbs. about 4 months ago and am now down to 139 lbs. and still going! I feel like I don't really have to try that hard--I still get my favorite roast duck from China Town, but now saute' a smaller portion with tons of veggies and am so full I don't want to eat the whole duck like I used to!

I've used some of these principles successfully for years and with Rolls' explanations, I was able to refine them to be even more effective. Her discussion of the various aspects of satiety really hammers home what you need to do to be successful in long term weight control. You have to be aware of what satisfies you and what doesn't, and learn the skills for creating meals that satisfy with just the right amount of calories. This is much more than a "diet" it is a guidebook for successful lifelong healthy nutrition. You have to learn the skills and take responsibility, but this program gives you the best long term strategy I think.

With the holidays around the corner I'm getting my diet started early and picked volumetrics cause it allows me to eat a good amount of food without feeling starved like some diets and still shedding 1-2 pounds a week.

I LOVE the food options and recipes they have and have starting seeing the pounds melt off - easy to read book too!

posted Oct 4th, 2008 4:53 pm


Absolutely the best "diet". I wouldn't even call it a diet I would call it a new way of eating. In 3 months I lost 24 pounds. I was not hungry at all. I would definately recommend this to everyone

posted Apr 3rd, 2008 8:41 pm


I did Volumetrics for awhile. I did very well. The recipes are delicious. You will definately be full. In 3 months I lost 24 pds. I actually got the books back out to resume this way of eating (I fell off the wagon around Thanksgiving). It makes you see how you can adjust your favorite recipes to be more healthy for you.

posted Apr 3rd, 2008 2:25 pm


Rolls and volumetrics seem sound enogh. I love the idea of feeling full on less, and the thought that research is involved


i've seen some great reviews on this book...seems like it would work and a great way to lose weight

BACKGROUNDBACKGROUND Start the Diet Now Advertisement

The concept of having more for less is something everyone understands. How often have you eaten something small and walked away feeling satisfied? That's exactly what you'll learn to do from The Volumetrics Eating Plan. This New York Times Bestseller by Barbara Rolls, Ph.D. describes a way in which you can eat less calories and still feel full. Those fewer calories will result in fewer inches on your waistline.

Don't confuse Volumetrics with a diet - it's a lifestyle change cleverly disguised as a commonsense eating plan. Dr. Rolls is a widely respected expert in weight loss and her book and plan come with high praise. Volumetrics will not remove entire categories of food or overwhelm with rules, counting and guidelines. Volumetrics comes with a wealth of tools including meal planners, sidebars outlining health food selections and more than 120 delightful recipes- that are as easy and smart as they are tasty and nutritious. Best of all, they are all low calorie and will leave you filling full and satisfied.

Dr. Rolls has printed one other title - Volumetrics Weight-Control Plan, in which she originally discussed her vast research and findings on satiety, the ability to eat to a satisfying point without overeating. Volumetrics is flexible and allows you to use the plan to best fit your likes, dislikes and personal goals. Unlike a lot of diet plans, this gives you broad choices, flexibility, simplicity and the comfort of knowing it's all backed by sound and highly-respected research. Prepare to have your mind changed about eating and dieting.

So how does it work? Volumetrics will greatly decrease your current caloric intake and as a result you can expect to lose about 1-2 pounds each week. You'll enjoy fresh produce, lean protein with almost all meals, whole grains, good fats and low-fat dairy.

Volumetrics doesn't really use the word "No;" Instead it gives you choice and variety. For instance, really enjoy a tasty bowl of mac 'n cheese? Volumetrics makes it just as satisfying with far less calories by using whole-wheat pasta, no-fat milk and low-fat cheese, as well as using less butter. Also, add fresh vegetables and you've got Volumetric's uber-satisfying Veggie-Stuffed Macaroni and Cheese. Fried chicken and cheese-soaked broccoli a sunday favorite? Instead, try chicken parmesan with asparagus, salad and even a dessert. This practice of substitution is applied to so many of your favorite snacks and meals that you won't believe you ever had them any other way.

Do You Know the Best Diet Pills of 2024?

  • A credentialed author, who is a professor at Penn State University
  • Has sensible weight loss goals of a pound or two a week
  • Some experts say satiety is relative, and that sometimes water-intensive foods may still leave some people feeling hungry shortly after eating.

A few of the more than 125 popular recipes include Bayou Red Beans and Rice, Penne with Olives and Spinach, Mediterranean Turkey Sandwich and Gazpacho Soup.


The book established exercise goals and explains some of the hidden benefits of even moderate exercise.


Volumetrics gets the stamp of approval from most experts. And even those who have some reservations don't attack the strategy on any deep level. While some people have concerns with the emphasis on making meals on your own, let's face it - pre-packaged foods are often high in sodium. All in all, this is an interesting and sound approach to eating.
