Prism Weight Loss Review - Does This Weight Loss Plan Really Work?

By Summer Banks Sep 20, 2017

This review is what happened after I obsessed for weeks over Prism Weight Loss. We did one of our in-depth reviews, closely scrutinizing the side effects, ingredients, scientific research and overall customer care. We additionally read dozens of dieter comments and customer reviews we found online. Finally, we summed up all of the facts and details to give you the important info you need.

What You Need To Know

Prism Weight Loss is a diet program that involves permanently changing your eating habits and reducing your daily caloric intake. It’s fine for women and men of all ages. More specifically, this is a Christian weight loss program that incorporates restoring overall health, emotional stability and spirituality. Prism Weight Loss was founded by Toni Vogt and Karen Kingsbury. This diet is supposed to help you ditch yo-yo dieting methods and get rid of unwanted pounds once and for all. Discipline and self-worth are important aspects of this diet, as is understanding food addiction.

The Prism Weight Loss method has been around since 1990. Children can also use this diet plan. Furthermore, healthy foods are encouraged with this diet and many unhealthy foods are cut out, but read on…

Diet Restrictions – A Consideration?

“It’s important to understand that you must permanently change your eating habits when you embrace Prism Weight Loss. Processed and refined foods are cut out, which some dieters do not like. Furthermore, you are expected to eat only 1,200 to 1,400 calories per day,” says our Research Editor.

According to one person, “I can’t stick to the low calorie amount, so the Prism Weight Loss method just didn’t work for me. Also, don’t care for the Christian aspect.”

Another dieter commented, “Too much calorie counting. I hate that! And sweets are a no no. I really hate that!”

Lack of Solid Science – Another Concern

We were unable to find solid science that supports the Prism Weight Loss method. Sure, anyone can shed excess pounds if they cut calories, but this is nothing exclusive to this diet plan. One person stated, “This approach did not help me lose weight. It actually made me eat more.”

“What research has been done to prove this diet plan works? It just seems very basic. I don’t see what makes it new or more effective than others,” said another dieter.

According to our research, if there is one facet of a diet program or supplement that is especially problematic (too many diet restrictions, high price, lack of real science) the odds of lasting weight loss are not good. In other words, if Prism Weight Loss does, in fact, have too many diet restrictions for numerous people to handle, this could be a major dilemma.

The Science – Is There Any?

At DietSpotlight, we prefer to see documented clinical research that backs the claims made about the diet plan or weight loss product we’re looking at. As for Prism Weight Loss, we were unable to find any solid science presented with this diet program. Needless to say, this is concerning.

The Bottom Line: Does Prism Weight Loss Work?

So, should you spend your hard-earned money on Prism Weight Loss? Well, we like Prism Weight Loss’s longevity as a diet program and some positive comments we saw about it online. Then again, we have some reservations about this weight loss program because it’s not backed by solid science. Moreover, we’re concerned about the diet restrictions that apply to this program, because there are a number of dieter complaints.

If you’d like to get rid of more weight, we encourage you to try a diet program or supplement that is backed by real science, does not require difficult diet restrictions and is supported by plenty of encouraging user reviews.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This supplement uses a blend of four ingredients, which have been proven in published clinical research to help speed up fat loss and elevate metabolism. We can’t locate any complaints of harmful adverse effects and user comments posted online show people are seeing substantial results.

The makers of Dietspotlight Burn are so satisfied with their product they’re offering a Special Trial Offer, which is a good sign.

What You Should Know

Prism Weight Loss is a program that is suitable for both men and women who wish to lose excess body weight. This weight reduction program lasts over 24 weeks and is separated into four or more phases that last six weeks each. Individuals can enroll for a single 6-week phase. The official Prism Weight Loss Program website states that it is "Christian oriented." This program claims to offer a new way of living for those who are overweight/unhealthy. Prism Weight Loss is not just a diet, but rather a lifestyle change. Participants learn about healthy eating habits and staying fit. The four phases involved with the Prism Weight Loss Program are Phase I (a first phase 42-lesson workbook, introductory video, a teaching video with 6 lessons and a transformation audio tape), Phase II (a second phase 42-lesson workbook and a teaching video with 6 lessons), Phase III (a third phase daily workbook with 42 lessons) and Phase IV (a fourth phase 42-daily lesson workbook). While the first phase costs $80, the other three each cost $60. With the Prism Weight Loss Program, participants have access to a discussion board, feedback and guidance, as well as online resources offered on the official website. There are customer testimonials presented on the official website for the Prism Weight Loss Program. It is not stated whether or not this weight loss program is offered with a 100 percent satisfaction guarantee. Since no dietary supplements are involved, there are no free trial samples available through the official website.

Product Features

Prism Weight Loss is a program that is marketed to all men, women and children who desire assistance with weight reduction or weight management. Although this is a Christian-based program, it is open to everyone. The Prism Weight Loss Program focuses on proper diet habits and eating/living healthy. There aren't any pills or supplements involved with this program. It lasts for a total of 24+ weeks, but can be purchased on a per-phase basis. These four general phases cost between $60-$80. There doesn't appear to be any clinical data offered on the official Prism Weight Loss website.


  • The Prism Weight Loss Program can be easily and conveniently purchased online.
  • The Prism Weight Loss Program is suitable for men, women and children.
  • There are customer testimonials posted on the official website.


  • The Prism Weight Loss Program may be too involved for some individuals who might desire a more convenient solution to weight loss, such as a pill or capsule.
  • There doesn't appear to be any clinical evidence presented on the official website to support the overall effectiveness of the Prism Weight Loss program.
  • There are no appetite suppressants or fat burners incorporated into the Prism Weight Loss Program.
  • The Prism Weight Loss Program doesn't appear to come with a 100% money-back guarantee.
  • A single phase of Prism Weight Loss costs $60-80, which may be too pricey for some dieters.
  • It may not make sense for non-Christians to enroll in this program.


Overall, the Prism Weight Loss Program is basically a lifestyle guide, which involves changing the eating habits of participants. Unfortunately this program will not appeal to some dieters who are looking for an actual weight loss supplement. Many people who wish to lose weight have already tried dieting with little success. In the end, it would be nice to see some kind of clinical data posted on the official website, along with a 100% satisfaction guarantee for the Prism Weight Loss Program.

You can’t. They aren’t in business anymore and I don’t know why.


Christy, Why do you say they are not in business. My cousin has been on it for awhile and is doing very well??

  Prism not offered in group meetings anymore
jerri cooper (Verified User)

Why is Prism not offered in group meetings anymore?? I also do not see any of the books Phase 1-4 anywhere. I loved the meetings, but moved and have not seen them for a long time. WHY !!!!!!!!!!!!

   I am Christian and loved the workbooks

I have used the Prism Weight Loss system before and did it through correspondence wit a lady names Susie. It worked well and not having to get on the scales and go to meetings, was great. I am trying to find out how to do that again, but can’t seem to. Please let me know what my options are. I like having to be accountable to a leader, like Susie. I am Christian and loved the workbooks! I hope you’ll be able to help me out with this. Thank you.


just to let you know this is a excellent program i was on it and did great but i stopped and the weight came back but as of today i will start again because the program really does work!!!!!!!

Hi Marilyn, I have a friend that is looking for the Workbooks for the Prism Weight Loss Program and can’t find them anywhere! Would you like to sell your Workbooks or do you have any information on where they could be obtained? Thank You! Carol Novicki

Jody Spira

Did Prism some years ago and want to lead a small group of ladies who are interested in it. Sorry to hear they went out of business. Does anyone know where I can get the work books 1-4 for a reasonable price new or very good used with no writing in them?

Stephen (Editor)

Have your tried Amazon?


Is the PRISM program still around? I can’t seem to find it!

  Program worked for my daughter
Pamela Edwards

My daughter went to the Prism group at a local church and did awesome. She started in February 2012 and ended in July 2012 and lost 61 pounds and is still loosing weight but doesn’t really need to anymore. She just really believes in the program and she inspired me to get on her train and I’ve lost 15 pounds in the first 6 weeks.

  Need help in menu plans
Ann LaChappelle (Verified User)

I lost 30 lbs on Prism diet in 2009. I was single and had a lot of time to devote to menus and recipes. I have gained back 12 lbs since getting married and working more. I do not have time to make up menus. Other diets have complete menu suggestions and that is an attraction. I would prefer to do Prism but outside of the one week of suggestions you give in Phase 1, there are no menu ideas that I can find……PLEASE help!!! If I was running Prism, I would make a monthly menu list available to busy women. Help me chose your diet!! Give menu plans!!!! Any suggestions?

Deb R (Verified User)

This has gone out of business

Deb R (Verified User)

I tried Prism years ago and loved it! It really does work. I am a Christian so loved the scripture reading. The weight loss is fast but also one feels ten times better. I should never eat white flour or sugar. I gained it all back and want to do it again. The group I was in all lost their weight with only a couple of us gaining it back and that was me. I am an emotional eater so for me to do it again, I need to deal with not eating when I am upset or bored. That will be the hard part.

  This product helped a lot
kibby (Verified User)

I did Prism 5 years ago and the principles have stayed with me. It’s helped with behavior modification and understanding why I eat when not hungry; and just appreciate healthy food more.. I have the large daily workbook to quickly refer back to and get encouraged from when I need a refresher. There is SO MUCH good info in it; I can’t begin to express how much I learned. After the time I put in to see how many calories basic foods have, I can no recall quickly how much I’m eating and to back off, eat slower, decide if a particular food is worth the exercise it’ll take to burn it off later.. SO MANY good things I learned. Very Very thankful for this program.

  any suggestions
polly dewey (Verified User)

I did the Prism Diet 12 years ago, but have gained the wt. back. Cannot seem to get going on it again, do you have any suggestions?


Yes – begin again. You did it once, you can do it again!
Planning meals ahead and shopping for only those foods,works for me.
Find the items you and your family like to eat, then plan two weeks of compliant meals around those healthy foods, keeping to your calorie count and only purchase food you can eat. Know a week at a time what you will be eating.
Blessings. I’m in for a life time of healthy eating for me and my family. At 61 & 63 we do not take any medication for any dis-ease process.

  I now need to loose some weight again
Anonymous (Verified User)

I bought the book, & did the program with my Church about 5 years ago. I now need to loose some weight again. I still have the book, but have misplaced the phase 1 food chart ( to let me know what I can & can’t eat) is there any way to get a copy of the chart without having to pay $120.00 again?
thanks! Jen Morgan jen@thewhirlwind.org


I just recently bought an electronic copy from Amazon for $10.99. Yes, no sugar, but it has to be past the 5th ingredient.


No real sugar unless past the 3rd ingredient, no potatoes, and no flour

  Prisim is a life changing
Pamela Adams (Verified User)

I have been on the Prisim Diet for nearly 3 years, I’ve lost 90 pounds & kept it off. I Have only 10 more pounds to go to reach my goal. Prisim is a life changing diet. It works with GOD’s blessing!

Lori R.

My family needs to lose 400lbs. We want to do the prism program, but can’t afford it. Any ideas?


I looked at my friends used workbook, and was able to answer the questions and do the work, I lost 19 lbs in the first 6 weeks and that was close to my goal weight! Just look at someones used book if you can’t afford it.I guarentee you will want to order the next phase for yourself, then share it among your family.

Lisa Dalton

If you join a Prism group through a church, the fees are lower than doing it on your own. Though they don’t recommend this, you could buy one workbook to share, and each use your own spiral notebook for answering the questions. Talk to the group leader or pastor, and see if they will work something out. Prism is not like Weight Watchers or Nutri-system, where they’re in it for the money. Don’t let the money keep you from getting healthy!


You say don’t let the money stop you however if someone does not have the money to spend, how can that make sense? I don’t mean to be negative, just being real. If they don’t have the money it will be hard for them to think about doing this program. I too have very limited funds but managed to lose 40 pounds by cutting out junk food and walking. Those of us with limited funds tend to buy junk food but in reality real healthy food is cheaper in the long run because it takes less of it. Good luck to Lori R. and her family.

  Prism Weight Loss works very well.
Linnea Walden (Verified User)

About 15 years ago I participated in a PRISM weight loss program. Several people dropped out because it was tough. Those who remained lost the amount of weight they wanted to lose and were very happy with the program…whether they lost 10 lbs. as I did, or 75+ lbs. I now need to lose again and will begin today. This is a very strict program of tough love, and, in my opinion, that’s why it works faster than some other plans; you can’t cheat (yourself).

Paulette Sarver

Linnea, I too did the Prism program and lost but since then I have had problems with my knee and have to have surgery for a knee replacement. So not being able to walk, like we were, I have gained almost all my wieght back….excuse was sympthy food..:-( would live to comunicate with others to get back on track and compare notes with each other, like a support group.

  Very smart plan
kmags (Verified User)

great program….christian aspect serves as a daily devotional if interested. Lost 20+ pounds in the first six weeks…not easy, but a smart plan based on healthy life choices rather than quick fix

  bible verse on transformation that Prism uses?
sue conley

i would like to know the bible verse on transformation that Prism uses. All my stuff is in storage that I have, willing to email other Prism users. thanks.

COYA DUNKS (Verified User)



ANY one of ANY faith can benifit from this program. I was a group leader for years. It is about learning about yourself and finding the right amount of calories in vs out. We also had a Dr. from our area look at the program and he gave it a big thumbs up. My fathers Dr. has been telling her clients about the program. My dad has lost 50 lbs and has almost been taken off all med. its not an overnight or quick fix. But then again this is a life changing event not a weekend event

  Loved the product
Sheree Moon (Verified User)

After trying many programs, the holistic approach of Prism has changed my life. It truly is lifestyle change. I’ve lost 70 pounds and am pressing on to lose the remaining 89 before my goal.

theresa Marble

I have done the prism program and had great success. I am “retrying” to get it under control again. I can not find my info for phase one food list. I remember most of what is allowed but not the amts. Like how many dairy rice cakes per day are allowed. Can you help me?

linda hahn

Two rice cakes are allowed per day
