No foods are off-limits on the SlimFast diet.

If you keep up with the plan it works. Drinks, food, follow all the instructions. But if you have other conditions such as thyroid and other problems it doesn't work as well but it helps along with the meds. I would say it's a good product overall.

I was unsure about diets altogether but when I started using SlimFast I was surprised to get the results you are trying to achieve with a little exercise. I actually did lose weight while I was using it.

    The time I tried Slim Fast for weight loss it worked pretty well. I lost 30 lbs???. But years later I tried again and only lost 10 ☹️. I guess it just depends on the person and what you're going through at the time.

    SlimFast it has wonderful taste that fixes Rich. It's more like you're drinking a mulch and then a diet product. I've used it periodically now and then. There's always had good results with it. I don't think I have to say much more than that. That alone should speak for it.

    I actually gained weight drinking these. They seem to make me more hungry than I normally am. I stopped drinking these and actually lost some weight. I don't know what this drink has in it but it seems to make me depressed. I won't ever buy these again.

    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 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 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.
