Artificial Color: Man made chemical which can be extracted from common allergens, tar, and oil. It has no nutritional value, and is only added to give a unique color to the food.
Natural solutions for weight loss are available from the top 10 highest rated diet plans.
Cellulose Gel:Thickener and stabilizer found in things like detergents, laxatives, processed foods, and toothpaste. A study by Nature, the International Weekly Journal of Science found that it:
“induced low-grade inflammation and obesity/metabolic syndrome”
This type of inflammation can also increase the risk for chronic diseases.
Sucralose:Artificial sweetener that is around 1,000 times much sweeter than regular table sugar. A Duke University study found that it could lead to serious damage to health. It confirmed how sucralose:
“Alters Gut Microflora and Increases Intestinal P-Glycoprotein”
Healthy gut microflora is needed for many important functions, such as regulating the immune system. When rats were fed sucralose, there was an increase of P-glycoprotein. This is only created within the body when a potential contaminantneeds to be fought.
This artificial sweetener has been used controversially, since there have been a few studies showing how it might be potentially harmful. A comprehensive top 10 list of the best diet plans is available in this link.
Carrageenan:Thickener made from red seaweed. Studies have been performed which show it may potentially cause inflammation in the body.
One study by the University of Iowa found:
“cancer-promoting effects of undegraded carrageenan...widespread use of carrageenan in the Western diet should be reconsidered”
The clinical study advised to limit the use of this ingredient since it’s possible for it to lead to unwanted side effects. It also is only found in processed foods.
FD&C Yellow 5:Artificial food dye added to give foods a yellow color. It’s known to be one of the most allergy causing of all food colorings.
The Center for Science in the Public Interest has tried to ban this ingredient, due to its lack of nutritional value and potential for side effects.
FD&C Yellow 6:Food dye that can be extracted from things like petroleum and coal tar. The University of California, Los Angeles has found that:
“(Yellow 5 and Yellow 6) have been found to be contaminated with benzidene or other carcinogens.
Soy Protein Isolate:A 90% soy protein by weight extract. It’s often GMO and it can potentially lead to side effects such as:
• Allergies, reduced testosterone, and increase estrogen.
• Reduced mineral absorption, increased risk for gout, and mood swings.
Soy also has what’s known as phytoestrogens, phytates, and goitrogens. This can potentially lead to unwanted side effects.
Corn Syrup:Processed sweetener that is extracted from corn, it’s a cheap sweetener often found in many processed foods.
There is also no book or guide to the SlimFast 321 Diet Plan, it essentially offers snacks, shakes, and a suggestion to eat a 500 calorie meal every day. This can be hard to sustain for some, as the only non-packaged foods allowed is one meal.
No recommendations are offered for what the 500 calorie meal should be. 500 calories is also not a lot for a full meal.
A guide of the top 10 best diet plans is offered via the link provided here.
EDITOR’S TIP: Combine this diet with a proven meal replacement such as 18 Shake for better results.
The SlimFast 321 Diet Plan Quality of Ingredients
Ingredients like artificial colors, food coloring, sucralose, soy protein isolate, carrageenan, and others are cheap to add and not necessary. These ingredients are cheap substitutes for more wholesome additives.
There’s a possibility for side effects and the basis of the diet is very simple. With the reduced calories it’s likely one will lose weight. However, this can be done with any low calorie foods. Many of the additives in SlimFast products aren’t actually proven good for the body.
The ingredients in the plan are artificial, processed and not natural. This makes this an unsuitable weight loss diet plan.
The Price and Quality of The SlimFast 321 Diet Plan
Prices can vary depending on where one buys their SlimFast brands from. A 4 pack of the high protein meal replacement sells for $6.93 on, the 4 pack of granola bars sell for $5.89, and the 100 caloriesnacksrange from $4.93 on Amazon.com.
Though inexpensive, the quality of ingredients is poor, and many customers have said that it does not suppress appetite. Many artificial colors, thickeners, binders, and other processed ingredients are added. The kinds of ingredients added are poor and cheap to source.

Thanks to dr.mack201@gmail. com for his wonderful work, My girlfriend left a week before our vacation to be with another man. I was desperate to get her back when I found dr.Mack. I don’t know how I found him, I don’t remember. But, when I first saw the good testimonies about his wonderful work and after reading the Testimonies, I decided I had to try. after his spell, I got a text from my lover. And we started going back and forth by text, she asked to meet the next day. So we did, and that night we ended up sleeping together, and about a few days after we got back together. anyone who needs help, should email dr.mack. He is the best.

I think I'll stick to my doctor and our diet. Diet plans always leave me confused and frustrated.

+I've done great on it. Then again, I don't like to eat much. I eat a bigger meal because I am a bigger girl and I intake around 1000 to 1200 calories a day instead of the barely 1000 they want you to eat. I may also eat a nutrition bar. Took me off my weight loss plateau.

+Slim fast does work, as anything will if you are dedicated to it; I think on the 321 plan, it helps those with sweet tooths because it cuts your cravings. I too have statrd the plan this is my first day and i will pray for success and give it my all. i did the HMR prgram , but is was way! too costly, couldn't afford it.My friend was on the slim fast 321 plan and lost a great deal of weight, its all about being committed ; I know we can do this, lets work tpgether to accomplish our personal goals; please feel free to email me at anytime, I need the support as well as different variety of suggessions. My goal is to loose 100lbs, no slow healthy way with slim fast; i too will be eating my 500cal for lunch and sometimes switching for breakfast; dinner is when I will have my shake to avoid over eating too late as I work long hrs most of the time. Overweight people are despearte for fast change, I'm one of them, but we must condition our minds to think slow. Again we can do this, because I'm tired of feeling fat and can't fit into normal jeans. I will succeed with the 321 plan on Slimfast. We will succeed!.

-Terrible....
posted Sep 23rd, 2013 7:42 pmTried this for a week and was not impressed at all. Even after just a week I was so grossed out by the sweetness of the products you have to stick within. And I'm not even a diabetic
The meal bars were like eating a chocolate bar, the snack bars are like chocolate bars too. Then when you come to meal time your so sweetened out you feel sick you can't even eat or you eat too much trying to get the sweetness out of your mouth.
The shakes are alright by themselves, Definitely try adding fruit of any kind, makes them a little easier.
But each to their own... I kinda benefited trying this though. Got so sweetened out that I'm not wanting anything to do with anything sweet for quite awhile!

?Up to how much weight could I lose in a month? I'm 23 years old, and I'm 5 ft. 4. I've never been this big. I weigh 153 lbs. It's really messing with my social life because now I don't feel so social. I don't like to go out. I worry people might be shocked when they see me being that I've always been thin. The biggest anyone had ever seen me was 129 lbs. I am now 24 pounds above that. I'm on day 3 of the 321 plan. I'm extremely dedicated. I'm exercising daily and plan to at least an hour a day, 7 days a week. I'm following the 321 plan as I should. I'm taking mega t green tea, and peach and fiber Omni life drink.

Everything I've tried taste good. I feel sufficiently full, not bloated, just full. Started working out 3 weeks into it and its fine too. Been doing it a month now. Used it to lose weight many years ago but now so many more options makes it more fun. Love the meal bars and snack bars plus choc, van & straw ready made shakes. Can't wait to try the chips type snacks.

?Does my diet plan sound reasonable ? So far day one - just spent a blinking hour drinking one for breakfast, as it made me feel full - it didn't taste awful either. (I'm usually hungry within 2 hours of eating breakfast) I've been meaning to diet for some time, as I put on weight since last summer for various reasons - making me the heaviest I have ever been, but my eating habits were better and I wasn't drinking as much, etc, and I've never tried to lose weight before - I've always been active, now probably not so. I am eating more fruit and calorie controlling through my fitness pal app, and instead of limiting myself to the calories on slimfast, will eat right, and to the calories on my fitness pal that are designed to make me reach my goal over a matter of time .. having a slim fast for breakfast, and for lunch if I'm at home, but a reasonable pack lunch if I am out. I do not count any exercise on my fitness pal app, against my calorie count, as I feel I would be naturally doing this exercise with my previous lifestyle. I'm 23, 5'5", and just over 12 stone, I wish to be 10 and a half ideally, but 11 / 11.5 would be GREAT for now - all my friends say I look like a 12/14, but I've just pushed over a 16, yet I'm still parachute pants in 18's. All I'm trying to do is get back to my once fairly athletic figure, fit in my old clothes and not drown my small waist !! Does this sound a sensible, and diet effective way to do things ?

+To be honest yes it is terrible to only drink or eat slim fast products, but this is not the message they are giving out to people. If you do read more into the 321 diet, it tells you what to eat on a daily basis along with the slim fast products to help you loose weight. So those who are being negative, this diet includes actually healthy food as well as well balanced meals. Those taking only the shakes and bars are doing it wrong. But it's their body, no right to judge.
posted Feb 7th, 2012 8:56 pmIt works fantastic and I'm healthy says my doctor. Just make sure you are taking this diet correctly. There is nothing wrong with it. Just speak to a doctor before starting any diet, your health is important too.

?Does the slim fast 123 plan work for smaller people? I'm a 5'2 female who weighs 105lbs, my goal is 95. Does the Slim Fast 123 Plan work for people who only want to lose a little weight? Or only if your big?
