Just bought this yesterday and tried my first drink this morning. It tasted so bad, it tasted like a chemical of some sort. Not sure I can drink another one. Vanilla was all Walmart had available or I would have tried chocolate. Terrible taste and it definitely doesn't keep you feeling full like others I have tried. I bought the 20gr protein drink.
I had all hopes in Slim Fast. I love the taste of their ready to drink advanced shakes. However, I have struggled so much trying to open the bottle with the plastic wrapping. I would literally have to use my teeth to open up the bottle. Therefore, I won't be using slim fast. I just wish they would have a simple twist off the cap bottle.

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.
Easy to use and follow, does not cost that much. Has lots of good products now for meals and snacks. Great flavors and always on sale at local stores or even Amazon. Take with you on the go, no mess or hassle to make anything.
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.
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.
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.
