Slimstyles Review - 5 Things You Need to Know


In my never-ending search to discover the best diet product, this week I reviewed Slimstyles. We took a good look at the side effects, ingredients, clinical research, and customer service. Then we read through more than a hundred reviews. All that information is condensed for you here, to give you the bottom line.

Slimstyles Readers: Click here to find out why we're giving away samples of our product, Burn HD.

What is Slimstyles?

First off, this is a meal replacement drink, but it also comes in capsules. Slimstyles ingredients include vitamin A, vitamin C, Vitamin D, vitamin E, riboflavin, thiamine, niacin, vitamin B6, folic acid, vitamin B12, biotin, pantothenic acid, calcium, iron, and phosphorus. There is some evidence that connects this method, though not necessarily this specific formula, to increased weight-loss.

Slimstyles is made by Natural Factors Nutritional Products. The company has ties all the way back to the 1950s. You can buy their products online and in some retailers. We like the company longevity and the variety, but read on…

Taste – “Yuck!”

Our first concern is the taste of Slimstyles ingredients. “This is a meal replacement, so it has to be something you look forward to every day,” says our Research Editor. “There could be a problem with this formula.”

”I did not really like this product. Has a strange taste and after-taste,” shared one unhappy customer.

”Nasty taste,” said another.

Others thought it tasted great.

“I have tried the French vanilla and is good but this double chocolate is like a dessert in itself and it helps me not to overeat like I always do,” one review said.

Hungry – “Meal Replacement or Snack?”

Our next concern is that for a meal replacement shake, many dieters reported feeling hungry, which could be a problem. If you feel like eating between meals, you’re less likely to stick to the program.

”I have 10 pounds to loose and didn’t. I included exercising and I was hungry all the time,” said one dieter.

”I felt like I was hungry all the time,” shared one user.

Others, however, found the shakes to be very filling.

“I tried this product (and other flavors) for a couple of months. As a meal replacement shake, it definitely does it’s job and keeps you full,” one person offered.

“It really works to help suppress your cravings,” said one.

One thing we’ve learned over the years is that all it takes is one little thing, like bad taste or feeling hungry, to send dieters in search of a better quality product. If Slimstyles wanted to keep customers, they’d take these user complaints into consideration.

The Science – “Does Research Support It?”

We are thrilled to say there is proof that meal replacements and protein can help with weight-loss. What’s missing with Slimstyles is that there’s nothing saying it is better than others you can find on the shelves of your local superstore. At DietSpotlight, we want to see science before we can recommend any product, but we also want to know our readers are getting a good deal.

The Bottom Line – Does Slimstyles Work?

Is it time to clear the shelves of Slimstyles? No. There are many other meal replacement products out there that may taste better and do a better job of filling you up. That’s the dilemma and the reason we have concerns about suggesting it.

If you want to shed those extra pounds, why not try using a weight-loss supplement that contains clinically tested ingredients known to help support your goals? To get even better results, use it with diet and exercise.

Among the best products we’ve seen this year is one called Dietspotlight Burn. We love it because we couldn’t find any negative comments or suggestions of harmful side effects, which tells us people are getting great results. It’s made with a unique blend of clinically tested ingredients designed to help support your weight-loss goals. With this one you won’t have to worry about taste or hunger.

Plus, anyone who is interested can take advantage of a special trial offer, direct from the manufacturer. This is always something we like to see.

  • Vicki

    I always thought I needed a tummy tuck as I couldn’t lose belly fat.. Consistently drinking a morning shake has taken that fat away and I have a flat tummy!!! I believe you must drink it almost daily. I will be using it forever.

  • Candice Gunderson

    I’ve started a medically assisted weight loss program that basically consists of replacing two meals with this stuff and then eating a small balanced dinner. I’m a texture eater – the texture of something can make or break a meal for me and I have to say this stuff is DISGUSTING! I could live with the watered down chocolate taste or even the protein powder grit, but it congeals into a syrupy gel with little clumps of powder that refuse to blend out no matter how much water I use! So gross! I feel like something that replaces 2/3 of my food should at least taste good and this is not it

  •   no need anymore
    Your Name (Verified User)

    After having children and aging, I airways felt pregnant even though I wear a size 6. A Slimstyles shake every morning has taken that chubbiness around the middle away…seriously! I always thought of having a tummy tuck but no need anymore!!!

  • Anyone gained weight?
    Cat (Verified User)

    Have been doing this for 2 weeks my blood sugar has been good but I gained 3 lbs. and I am following verbatim. Has anyone else had this issue. It is depressing to feel this hungry and not lose any weight!


      I have been using this product for 2 weeks and I am at the same weight as when I started. I was told that I need to incorporate exercise into my program to see results and be successful at weight-loss goals.

  •  Drink lots of water before and after
    Nancy (Verified User)

    I have been using SlimStyles along with Weight Watchers Points system, now for 7 weeks and have lost 20 lbs. I love the shakes especially the Pina Colada one, it keeps me full, but remember drink lots of water before and after drinking the shakes, and in Canada I find the most economical place to buy is online at NationalNutrition.ca,(right now $34.99 for the shakes) just log on to their website and they have all the PGX Products,

  •  blenders and even a hand mixer
    Debbie (Verified User)

    Hi I have been using the slimstyles double chocholate shake mix once a day. The only problem I am having is that I find it really hard to blend. This is my second time buying it and both were like this. I have to waste a lot as there is always some at the bottom of my glass. I have tried the shakers, the blenders and even a hand mixer. Has anyone else had this issue? Thanks.

    • Atif Baig


      Try 2 scoops in 500 ml water or 1 scoop in 350ml. I use a hand mixer and it works perfectly fine.

  •  lost eight pounds a
    Susan Larson (Verified User)

    I have been using Slim Styles drink for about three weeks. I’ve already lost eight pounds and use it in conjunction with my weight watcher points. It is absolutely wonderful. It helps my cravings and keeps me from starving between meals. Of couse, I have to do all the other things that help maintain weight loss…the things that I’ve learned in my weight watcher meatings.

  •  I actually prefer SlimStyles
    Elena (Verified User)

    I have been using the SlimStyles shakes for 2 weeks and have lost 7 lbs. I read all the materials and they say to replace breakfast and lunch with shakes and eat small healthy snacks and a lower calorie diner UNLESS you tend to overeat at night which is what I do — so I have a shake for breakfast, eat a big salad with chicken or tuna at lunch and then have 2 more shakes — one for dinner and one for an evening snack. I’m not hungry in the least, no cravings (have my chocolate shake in the evening!)Its a Canadian product, available at all health food stoes in Canada–I pay about $39.99 for the big container (14 servings — so thats like 2 meals a day for a week – instead of spending tht money on groceries.) By the way, I mix it up with unsweetend Almond Breeze (40 calories per cup) and a little water, much creamier and satisfying that way.
    I actually prefer that it does not contain fat burners and appetite suppressants because those are things I won’t need to wean myself off of. I’m doing this all by myself!

    • missy

      hi and thank you for all the infor you are providing. I am just starting the pgx diet and i was wondering if you have any tips or ideas such as the snack at night idea lol thats a good one! how much is the max you can take from the shakes 3 a day?

  •  I used it for a week and gained weight
    j (Verified User)

    have only used it for a week so far but have gained a pound. not what i’m trying to do. getting support or answers from customer service is like asking my appendix. all they do it cut and paste from their brochures, even when i ask their nutritionists. probably won’t be buying another tub. it ain’t cheap. it’s over $50 with taxes.

  •  Quite happy with product
    Sharon (Verified User)

    I have found the Slimstyles MR product very good in conjunction with type 2 diabetes; blood sugar numbers very good after a shake.The Vitamin Shop in Victoria (canadianvitaminshop.com) has the products price 34.98/ea .Quite happy with product

  • I have had no significant weight loss yet, but it seems to help
    Jeanine (Verified User)

    I have been using slim styles for about 3 weeks, I would have to say it keeps me full allot longer than other shakes, and believe me I have tried them all. It takes about a week to get used to the amount of fiber, ie, bowel cramps and bloating, but then it levels out. I have had no significant weight loss yet, but it seems to help. I also use the PGX granules with water or yogurt and that helps too.

    • Jeanine

      Price wise it is high here in Canada, between 45 and 50 dollars for the shake alone and 4o for the granules. There is not much volume in the shake mix. It is also good for lactose intolerance because you mix with water.

      • Nancy

        Check Nationalnutrition.ca
        the Shakes right now are $34.99, all the flavours

  •  This is my first trial of this product
    Al Mitchell (Verified User)

    this is my first trial of this product, and after reviewing the ingredients I feel it is worth trying because after talkin with my doctor because I am diabetic we feel that it will be benefical for both contol of my blood sugar, as well as my blood pressure, and will not be affected by my current medication regieme

    • Elizabeth

      Its a great meal replacement, i use it twice a day. The trivk for mixing (for me) is to add the liquid to the shaker first and the powder second. No clumps!
