Slim-Fast
Slim Fast is a weight loss program that substitutes cooked meals with shakes and bars. The program is over 25 years old, and is currently a brand owned by Unilever.
Background
Slim Fast has been a popular choice for weight loss. However in recent years, Unilever has struggled with declining sales – at first blaming the popularity of Atkins. The original Slim-Fast shakes were criticized for being too high in sugar. This was rectified by replacing sugar with the artificial sweetener Splenda. The new range of Slim-Fast products are called Optima.
Slim Fast Products
The Slim Fast offerings comprise the following:

- Optima – Shakes (Ready-to-Drink), Bars, Smoothies, and Powders
- Original – Shakes (Ready-to-Drink), Bars, Smoothies, and Powders
- High Protein – Shakes and Meal Bars
A typical shake (Optima Cappuccino Delight) contains the following:
- 5g Fat
- 24g Carbohydrate
- 10g Protein
- 180 Calories
- 24 Vitamins and Minerals
Diet Plan
The diet involves replacing two main meals with Slim-Fast products. Each day will also include one “Sensible Meal”, and fruit/vegetable snacks. A sensible meal is based around a lean protein (such as skinless chicken breast, or fish), carbohydrate (potato, rice, or whole wheat bread), and a large serving of vegetables.
Sample Meal Plan
| Breakfast Optima Cappuccino Shake & 1 slice frozen French toast with 1 Tbsp light syrup |
| Snack 1 cup grapes |
| Lunch SlimĀ·Fast Optima French Vanilla Shake & 1/2 roast beef sandwich (2 oz. Roast beef, 1 slice whole wheat bread, 1 tbsp horseradish, lettuce, tomato) |
| Afternoon Snack 1 apple |
| Dinner Chicken Veggies Grill:
1 cup melon |
| Snack One slice low fat pound cake OR Peanut Butter crunch Snack bar. |

Is Slim Fast Successful?
The Slim Fast diet is a sensible and workable plan, and many people find the convenience of using meal replacements outweighs other diet plans.
There is one study that Slim Fast cite claiming that “People who followed The SlimĀ·Fast Plan routinely to lose and manage their weight were, on average, 33 pounds thinner after a decade as compared to a matched group from the same community who did not participate in the study. (reference: Blackburn GL. et al. Obesity Research 2003;11:A103)”

I HAVE A QUESTION!
there used to be these slimfast bars, the traditional ones, they were the best. these are called optima now. the snak ones were great. they discontinued. i always lost weight with them and now i cant get them from anywhere. they were square sized ones with red label, says slimfast lunch and breakfast meal option ontop. lower in calorie. and i think those were the first slimfast snacks made. aaahhhhh wish i could find them. i dont like these new snacks. they have too much carb and calorie , which i dont find helpful. its just too much. !!!!!!!!
Hi everyone. I started slim fast April 29, and so far have lost 17 pounds. And I do go out to eat at least once a week, you can’t deprive yourself. And I also only weigh myself once a month, I think it’s better that way, after that time of the month, I just feel it makes a big difference.
I started the Slim Fast diet about a week ago. I work out every day at the gym for about an hour and a half to two hours, and every few days do about 45 minutes of Zumba. I’ve been doing relatively well. The one thing I’m worried about is after I reach my goal weight. I’m worried that once I stop drinking slim fast, I will gain my weight back. Once I’m at my goal weight, I will obviously make sure all of the food I eat is very healthy and sensible choices. No more junk/fast food. Will this work? I’m just so tired of feeling like a pariah because I’m overweight.
So, if I generally eat a low calorie diet and continue exercising on a regular basis, will I be able to maintain my ideal weight?
Thanks a lot
Hi PB, You’ve discovered the problem with meal replacement products. They never teach you to eat right. Why not save your money and just eat healthy calorie controlled meals now? Here’s a site that can help with eating plans and calorie calculators. http://www.freedieting.com Good luck!
Just finished my first week on SlimFast 321 plan. Messed up a few days with an extra piece of chocholate or granola bar here or there but still lost 2 lbs. Haven’t increased my exercise but still managed to lose. On to week 2 this time I’ll be better. Goal 140 current 161
Hi there, I started Slim Fast 4 days ago-I broke last night and had sweets etc but I’m back on it again today. I want to lose 16 lbs, I would like to hear from anyone else who has slipped up and got back on it.
I started this diet three ago and lost 10lbs. For coffee lovers the mocha, vanilla, and choc. taste great in your coffee and you dont have to add the extra calorie with creams or milk and sweetners.
i have been looking for slim fast coupons and without luck, i can’t find any.. Will someone help me find them please

im starting the slim fast diet today! i weigh 170 lbs… im hoping to lose 60 pounds in 2-4 months… it is suprisingly filling! hope it works for all you guys!
I am 3 days into my 4th week on slim-fast…although i am lossing its pretty slow compared to what others say they have lost. I have a shake for breakfast, a snack bar mid morning, a shake for lunch and another snack bar in the afternoon. I have a healthy dinner. Sometimes i have the recommended 3rd snack if I need it later. So far i have lost 7lbs I am not a very big person but put some pounds on when I gave up smoking over 4mths ago that I want to come off.
can the slimfast 321 plan work if you go out to eat?
Yes, With Slimfast you are to eat one healthy meal a day so Your eating out could be that meal, but you have to choose something healthy from the restaurant .
i started slim-fast 2 weeks ago and i am almost to the 10 lbs mark i love this diet it is really easy to follow but i changed mine a little bit to fit my schedule i have a shake for breakfast a shake for dinner a snack bar or another 100 calorie snack and i eat what ever i want for dinner since i already have a slow metabolism i did not get hungry before this diet i just ate because i knew i had to in order to live and i still do not get hungry but i also do not get super full or bloated anymore
I just started the diet today! Had a shake this morning, snack bar, and a shake for lunch and I feel full. It’s amazing! Loving it so far
How can I get cappiccino flavored powder mix in Slim Fast. All you have is choc, strawberry and vanilla..I won’t buy the cans since the recall….
I used slim fast to lose weight when I had my first daughter and it worked great…well another kid and about 5 years and I am the biggest I have been about 190lbs…I was diagnosed with PCOS and from the way the Dr. described it one day I will become a Diabetic unless I lose weight, I am also trying to concieve so before it will work I need to lose some weight. I hope this works with the help of some medicine she has me on.
Hi, am willing to try for this slim-fast diet. Is there any store here in UAE who are selling this product?

Can I take slim fast if I have a cholestorol problem?
i lost 20 pounds in 2 weeks doing slimfast. all i do is drink 2 shakes a day have one healthy meal and 3 snacks in between. i love it.
is slim fast really works?
@cheska, anything that causes you to eat less Calories works, but the question is does slimfast teach you to eat smaller more nutritious meals or is it just a quick fix that will not generate long term results?
i just started doing slimfast i weigh 185,and i want to loose 50 pds. i eat 3 snacks 2 shakes 1 meal usually a salad. i use to weigh 253 i got to 165 doin atkins. i gained
some back i love sweets so hopefully it works i love the penut butter crunch snacks. so i walk 30 mins daily.does anyone know if you can have coffee black or just water
My mom did this diet for 8 months and lost 70 pounds. She kept the weight off until she had another baby. I reccomend to anyone who plans on being active. If you just think you can lose the weight and not gain it back and your one of the lazy ones, this diet is not for you. Yes this will make you lose a good amount of weight but exercise is the key to keeping the weight off afterwards.
i didnt know it had suger in it ill try it. Thank U
I just went out today and got the SlimFast powder shakes, can shakes, and the snack bars, I’m planning to lose some weight after gaining ot back from previous diet pills (Fast Slim) I weigh about 137.. hopeing to go down to 120.. i’m a bit on the wider side since I’m only 5″2…
IAM DIABETIC SO IHAVE TO WATCH WHAT I EAT.
