I started Slim-Fast a year ago and in 6 months I lost 16 pounds! I am usually horrible when it comes to dieting but the Slim-Fast plan is pretty straightforward and if you really stick to it and don't cheat you will get results! It takes time but it works.

I love the caramel and the cappuccino delight. In the year I have been drinking the shakes I have lost 30 #’s and feel great. I use my own snacks during the day such as cheese sticks or summer sausage sticks. It is the easiest diet to stick with. It’s not a diet plan but a way of life plan.

No foods are off-limits on the SlimFast diet. When you buy the company’s packaged snacks, you don’t have to worry about portion control or counting calories except when you’re eating your one meal of the day. While there’s no formal program, SlimFast encourages participants to exercise regularly to get the best weight loss results.

  • 100-calorie snack packs
  • Shake mixes
  • Meal bars
  • Coffee creamer

SlimFast shakes come in regular, low-sugar and high-protein options. Each serving of SlimFast’s original shakes contains 120 to 130 calories, 10 grams of protein, 5 grams of fiber and 24 vitamins and minerals.

  • Advanced Energy has more caffeine than your typical coffee. Advanced Energy products give you an extra boost from their high energy content.
  • Advanced Nutrition has fewer carbs and twice the protein. Slimfast Advanced Nutrition’s extra protein curbs your appetite while keeping your sugar intake low.

Does SlimFast work?

Both my spouse and I have used Slim Fast. I like the chocolate flavor; he likes vanilla. We often make shakes in the morning by putting skim milk, slim fast and ice cubes into our blender. The slim fast comes out thick and frosty and super delicious. Slim fast satisfies our appetite.

I am a big fan of Slim-Fast. I have been taking Slim-Fast for over 10 years. I would recommend anyone to drink Slim-Fast shakes along with a low calorie meal and a exercise regimen but I also would tell anyone to go to the doctor before starting any diet. I will also advise anyone to walk 2 miles a day and do cardio and swimming exercise. I dropped two pants sizes in a year. Slim-Fast comes in a variety of flavors. My favorite was strawberry. I'll have a steak in the morning and during lunch hours and then eat a low calorie meal and I drink plenty of water.

    I purchased the fatbombs by SlimFast as I’m on a Keto diet. First and foremost, they taste like the things dreams are made of. I got the ones with nuts, caramel, and chocolate. There was an issue as in a few had the caramel been all over the packaging Instead of inside the chocolate. I took pictures for proof of issue and purchase of course. I sent an email outlining the issue. They responded very quickly and apologized and asked for my mailing address so they could send a coupon to replace my product! I didn’t have to argue. I didn’t have to debate. They sent out that coupon just as they said.

    I put it in my glove box to use the next time I went to the store. I kept forgetting in the car. I finally remembered it so I went to pull it out of the mailed envelope and noticed it expired. I was bummed because this was my fault. Just on a wish I emailed the support person back (Susan D.). She not only responded but said they reprocess my request and send out another! When a company treats their customers like this, they earn my loyalty.

    Well, last year, I was at 245 lbs, I couldn't find anything that would help me lose weight, much less keep it off, not even so called weight loss pills. I started using Slimfast I bought at Walmart here in my town, switching between vanilla and chocolate for the powdered cans. I did try the snack bars, but I didn't really like them. I have found though, that I lost 10 lbs the first time using a combination of Slimfast, using my medical cannabis, and some light excersice, since I have asthma. I am now using it again now that I can afford it again, to try and lose some more weight. I went a good 3 months without using it, but still had a nice surprise of my weight staying off, so here is hoping I can get down to 180 lbs.

    I have tried the SlimFast diet and although they have pretty good food, drinks and snacks they do really work that well. And the food the snacks have a tendency to upset the stomach so I had to stay away from them. Though I lost 20 pounds in 4 months it was I think more of the exercise on my part than the weight lose program.

    I have medical issues that can make eating difficult & exercising even 30 minutes a day difficult as well. I thought cutting calories, while getting nutrients & protein I was lacking, with an easy answer like pre-mixed SlimFast Advanced shakes was a great idea. It. Was. Not! The "advanced" flavors are actually pretty good. I chose Caramel Latte with extra energy for mornings (really liked this flavor, at first), & alternated between vanilla & strawberry for afternoons. They definitely keep you full! BUT, that's because, if you don't take twice the regular dose of an anti-gas med before drinking them (& occasionally, even if you do) you'll bloat up, usually within a half hour, & feel like a parade float begging its handlers to deflate it & bring it back to a comfy spot on earth to recover! I'm seriously NOT joking! :/

    I'd feel a sudden & uncomfortable fullness, then realize that my previously loose shirt had started feeling & actually looking tighter as I watched in horror! Before I could waddle to the gas reliever, the shirt would be so tight & my stomach so badly distended I was sure I'd be asked my due date or be bursting through my clothes & turning into the Hulk at any moment! Oh, the pain & embarrassment! Remember Wonka's fizzy lifting drink? If not, you will shortly after drinking this stuff!

    Speaking of embarrassment... the caramel latte claims to have the caffeine of one cup of coffee. Perfect for mornings, right? Wrong! Well, at least not if you plan to breathe in your own home or be around people for the next couple days. It too causes the intense bloating but has the added bonus (??) of making your urine, breathe, & sweat STINK like a rotten version of how the shake smells. It's so potent it will stick with you for at least a day, even if you haven't had another sip, let alone another full bottle.

    It's so bad (& only gets worse with each bottle you drink, even if you have another flavor) that it will make you leave the exhaust fan on & try to avoid your own bathroom for days. If you make the unfortunate decision to leave your home, people in public restrooms will undoubtedly ask if you're ok, or ask loudly, if you're lucky enough to not be pinpointed as the source, "Ugh! What is that awful stench?" You'll want to chime in that it IS horrendous in hope that your mutual disgust will keep them from realizing you're the reason they're now nauseated - but don't do it!

    If you open your mouth, or even lift an arm to cover your nose with your hand in solidarity, you'll be discovered as the source of the stench! Why? Because, while, admittedly, in slighter lighter tones, the stench does also waft forth from your breath & even a light perspiration that normally would go undetected! Depending on your acting chops, you may be able to pretend it's now adhering to everyone in the vicinity & walk away unscathed as you help innocent bystanders leave the soon to be condemned bathroom. But, more likely, you'll be forced to apologize & explain your misguided quest to get healthier has led you to become a stinky, balloon version of your former self.

    Soooo, the flavors aren't bad, going down anyway. That's one star. It definitely keeps you full & not wanting to eat. That's a second star. BUT the reason you don't want to eat, potential embarrassment, pain, & nausea, definitely leave the remaining stars empty - just as I wish I'd left my stomach, & my fridge that's now full of a month's supply of this nightmare in a bottle that I can't return! :'(

    I purchased 3 cans of Diabetic Slim-Fast. I opened the Vanilla Milkshake for the first time ever! The container was only 1/2 full. So I opened the 2 Chocolate containers and found it contained a little over 1/2. This is a scam. I reported it to Amazon. IMG_4544.JPG. IMG_4545.JPG. I will not be purchasing anymore Slim-Fast. Placed pictures on Facebook.

    There were not a ton of options and the shakes quickly became boring. I did not find them filling enough and did not see anything unique about the program to make it stand out.

    It is a good program and works fairly well. I found that there were not enough options for me to provide enough variety to keep me interested and actively engaged in using the products. I found that I was not feeling full enough and satisfied most of the time. More variety and flavors in options offered would greatly help the program.

    If you follow their plan you start getting dizzy and light headed by the afternoon because your sugar level drops because all you had that day was their shakes for breakfast and lunch.
