Why is it that so few diet products are backed by science? Let’s find out if Slim 4 Life is one of the good ones. We decided to dive deep to learn more about ingredients, side effects, and clinical results. We also read through hundreds of dieter experiences. We condensed the facts to give you the info you need.
What is Slim 4 Life?
First off, Slim 4 Life is a weight-loss program, not a supplement. You have to visit a center to get your personalized evaluation. Once the consultation is complete, your diet plan is created. The length of time prescribed in the plan depends on how much you have to lose. Locations are available throughout Kansas, Missouri, and Texas; good for some dieters.
Slim 4 Life was started in 1979 with an original location. Since then, additional centers have been added in three states. We were encouraged by reports of results from some dieters but read on…
Price – “Unrealistic?”
The first thing that worried us about Slim 4 Life was the price.  The fine print of the contract tells customers there is a $210 fee for starting your diet plan. You have to pay for visits, up to five per week, and Slim 4 Life products. “There are good weight-loss programs on the market that help dieters learn how to eat right,” according to our Research Editor. “Paying thousands of dollars for guidance is not a very good idea.”
“For me the plan was going to cost around $2000 to lose 60 pounds,” claims one customer.
“They advertised lose 30 pounds for $30, but it is only to get you through the door. Once you are there they begin to show you around, they get your weight and begin explaining the program and how it works. My total cost was going to be 4,300.00,” says another.
The high price is worth it to some dieters. As one said, “I was saving money by not buying fast food and junk.”
Another shared, “Yes the diet is pricey but it worked for me.”
Unsupported Weight-Loss Guarantees – “A Problem?”
Any diet that promotes calorie restriction is going to help you lose weight. The trouble is when the plan promises the follower they will lose an unrealistic amount. According to the fine print on the official website, the dieter is guaranteed to lose between three and five pounds each week.  This statement is followed by the information that you may lose more than that or less. There’s also a catch.
According to one plan participant, “But by not buying their products they cannot guarantee the weight loss.”
“I know that if I don’t purchase the other $1,500 in products, they won’t “guarantee” my weight loss, but I am going to try to lose as much as I can and then try to maintain on my own,” another dieter says.
Still another buyer claims, “Keep in mind they do not guarantee your weight loss if you don’t buy all their products.”
We found some dieters that claimed to lose upwards of 10 pounds a month, but none reported any loss that even came close to the promised results. There’s not a single piece of clinical evidence that a weight-loss plan, based on food restriction, is safe or immune to rebound weight gain.
Based on our research all it takes is one problem with a diet plan, like unrealistic claims, to lessen your chances of long-term success. If Slim 4 Life lures in dieters with false advertising and unsupported guarantees, we’re concerned.
Where is the Science Behind Slim 4 Life?
There is scientific proof that a reduced-calorie diet  paired with an exercise program  can help you lose weight. Slim 4 Life takes care of the eating plan, but the FAQs section says you do not need to move more. Without details of how the program works, there’s no way to find support. DietSpotlight looks for clinical proof supporting claims of weight-loss, and Slim 4 Life does not offer any.
The Bottom Line – Does Slim 4 Life Work?
Are you on the edge of your seat waiting for the final word? At first Slim 4 Life intrigued us. We like the good BBB ratings for several locations, and some users report weight-loss, but after looking closely at the facts, we don’t feel we don’t feel comfortable giving this one our recommendation because of the high price and lack of clinical support. Plus, we’re worried the diet may be too low in calories.
If you want to shed 10, 20, 30 pounds or more, we suggest a supplement that combines great ingredients backed by published data with an affordable price and no risk of side effects.
Among the best products we’ve seen this year is one called Dietspotlight Burn. We appreciate the proprietary blend with four ingredients proven to help you lose fat and increase metabolism. We were unable to find talk of any side effects and excellent results are mentioned time and again.
Also, the creators of Dietspotlight Burn are confident enough in their product to offer a Special Trial Offer, which is a benefit.
Previous Slim 4 Life Review (Updated September 11, 2014):
What You Should Know about Slim 4 LifeSlim 4 Life or Slim 4 Life is a weight reduction program suited for men and women alike. This diet system aims to assist users by teaching them "weight management and healthy eating habits." Slim 4 Life offers 30-minute consultations to new customers for free by telephone. Their main office locations are Denver Metro, Northern Colorado and Minneapolis/St. Paul. There are customer testimonials offered on the official website. No company background/history is found on the website, but it is stated that the Slim 4 Life system has been around for 25 years. Regrettably, this company has an "F" BBB rating. Similar to Slim 4 life, the Applied Nutrition product line also has weight loss products that can be used in combination to achieve results. Unlike many other weight loss supplements and diet programs available, Slim 4 Life is essentially a system that focuses on changing eating habits for a lifetime. Another similar program, although it doesn't last for a year, Whole Body Research is a supplement company that offers joint health, weight loss, digestive health and daily wellness. With proper education, counseling and supervision, dieters are supposedly able to achieve the weight loss they desire. No diet pills or synthetic supplements are incorporated into the Slim 4 Life (Slim4Life) program. Some of the foods encouraged with Slim 4 Life are vegetables, meats, dairy products, fruits, starches, eggs and fats. While doing certain weight loss programs, it is encouraged sometimes to incorporate cleanses like Iaso Detox Tea or supplements like FenFast 375. It is not stated whether or not there is a 100% money-back/satisfaction guarantee offered with Slim 4 Life. The average dieter is stated to lose 3.3 pounds per week. A regular exercise regimen is not part of Slim 4 Life (Slim4Life).
Product Features of Slim 4 LifeSlim 4 Life is basically a weight loss program that's geared toward men and women suffering from obesity. As opposed to incorporating diet pills and weight loss supplements, Slim 4 Life focuses on altering the individual's way of eating permanently. Therefore the teaching of healthy eating habits, counseling, proper education and supervision are all part of the Slim 4 Life program. It is not stated on the official website how much Slim 4 Life costs. A free consultation is available via the website and a phone number is provided for new users to take Slim 4 Life up on this offer.
Advantages of Slim 4 Life
- Slim 4 Life encourages "healthy" eating habits.
- Free nutrition consultation available over the phone for first-time users.
- Slim 4 Life is a weight reduction system offered to both women and men.
Disadvantages of Slim 4 Life
- There are no appetite suppressants offered with the Slim 4 Life diet program.
- There is no stated price for the Slim 4 Life program on the official website.
- There doesn't appear to be any substantial company background information offered on the website.
- The Slim 4 Life weight loss program would require a somewhat drastic lifestyle change, which may not be suitable for some individuals. (See reader comments.)
- There doesn't appear to be any 100% money-back/satisfaction guarantee offered on the Slim 4 Life website.
- Slim 4 Life only appears to have branches in only three areas, which are Denver Metro, Northern Colorado and Minneapolis/St. Paul.
ConclusionOn the bright side, the Slim 4 Life or Slim4Life weight reduction program is unique in the sense that it doesn't require users to remember to take pills. While this dieting system does encourage a specific way of eating/way of living, a few crucial aspects were left off of the official website. For example, often those looking to lose weight need extra help in the form of a appetite suppressant or a metabolic booster. It would certainly be nice to see some pricing for the Slim 4 Life program posted on the website, along with a 100% money-back/satisfaction guarantee and some real background information on the company itself.
Slim 4 Life is a weight-loss clinic that offers in-house or at-home programs. There are a variety of supplements available to use with the plan. The two metabolism boosters are Metabolizer and LipoCell. Both supply caffeine, which means it's not likely the best idea to take them together.

Sometimes called Brazilian cocoa or paullinia cupana, guarana is a plant that grows in certain parts of Brazil. Over the years, it has been used to treat conditions such as chronic fatigue, obesity, poor athletic performance, anxiety, headache and poor mental function.
What is it Supposed to Do?
Many diet supplements and energy drinks contain guarana extract. This herb provides a significant amount of caffeine, which is a stimulant. It is supposed to boost mental performance and increase energy levels.
Some studies have been conducted with guarana. In fact, one study from the Journal of Psychopharmacology, “Guarana improved secondary memory performance and increased alert and content mood ratings.” 
Also called citrus aurantium, bitter orange is a plant. The fruit juice, flower, leaf and peel are all used to make traditional medicine. This ingredient is sometimes used to treat fungal skin infections, diabetes, nasal congestion, obesity, upset stomach, constipation and chronic fatigue.
What is it Supposed to Do?
Some over-the-counter weight-loss supplements contain bitter orange. This ingredient provides synephrine, which is a chemical that may help boost thermogenesis. It is often combined with some form of caffeine. Also, it is considered an alternative to ephedra (a banned ingredient).
According to the Mayo Clinic, “While some research studies suggest that bitter orange (Citrus aurantium) can help with modest weight-loss when combined with diet and exercise, it’s probably not worth the risk. That’s because bitter orange can cause a range of potentially serious health problems.” 
First of all, gingko is basically a large tree that is native to regions such as Korea, China and Japan. For many years, this herb has been used to treat health conditions like Alzheimer’s disease, depression, eye problems, anxiety, poor mental function and dementia. It is found in a number of dietary supplements.
What is it Supposed to Do?
Gingko leaf is often added to diet supplements and weight-loss products to help elevate mood and improve mental clarity or function.
We did not find any direct link between gingko biloba and weight-loss. However, “Several studies show that ginkgo has a positive effect on memory and thinking in people with Alzheimer’s disease or vascular dementia,” says the University of Maryland Medical Center.
Asian Ginseng Root
Also called panax ginseng, Asian ginseng is a plant that is native to regions like northeastern China, Korea and Siberia. This herb is often used to treat poor mental performance, Alzheimer’s disease, low stamina, flu, anxiety, depression, joint pain and various other ailments.
What is it Supposed to Do?
Asian ginseng is included in diet supplements to help improve mental and physical performance. This may help with regular exercise and staying active.
WebMD says that, “Evidence shows that taking Panax ginseng root daily for 12 weeks can improve mental performance in people with Alzheimer’s disease.” On the other hand, this herb does not appear to cause weight-loss.
Among the best products that has graced our presence this year is Dietspotlight Burn, which has four salient ingredients proven in studies that helps ignite the metabolism and hasten weight loss. Consumers have raved about this fat loss supplement’s remarkable results.

Slim 4 Life Side Effects:
Natural supplements taken for weight-loss are not 100% safe. Any formula, natural or not, may come along with negative reactions. Even though Slim 4 Life side effects don’t happen often, they do exist for some users.
Contractions of the esophagus causing food to move from the mouth to the stomach irregularly are known as digestive spasms or esophageal spasms. They may be very powerful and may cause serious discomfort in the stomach and esophagus. These spasms may even keep food from reaching the stomach. 
What causes digestive spasms?
The causes of digestive spasms can be a mystery to doctors. However, many believe these spasms come from a disruption of nerve activity with the swallowing action of the esophagus. Sometimes, it can be triggered by very cold or very hot food.
Loose, watery stool is often referred to as diarrhea. It may feel like liquid coming out during a bowel movement instead of a solid mass.
What causes diarrhea?
Many things may cause diarrhea. The culprits range from a virus or parasite to a reaction to something ingested. It could also be a sign of inflammatory bowel disease or ulcerative colitis.
Difficulty with bowel movements is described as constipation. It may be associated with the hardening of feces and occurs when bowel movements are very difficult or happen less than normal.
What causes constipation?
Constipation may be caused by a number of different things including:
- Medications or supplements
- Laxative overuse
- Too much cheese or dairy
- Inflammatory bowel disease
Heartburn is a form of indigestion. It comes along with a burning sensation in the chest, which is caused by acid regurgitation through the esophagus.
What causes heartburn?
Heartburn is a symptom of GERD or gastroesophageal reflux disease. Many different things can trigger heartburn including spicy foods, a hiatal hernia, pregnancy, slow digestion and more.  It may be something as simple as a food or medication ingested or a symptom of something more serious.
Slim 4 Life side effects don’t happen in all users, but some have reported digestive spasms, diarrhea, constipation, heartburn and other negative reactions.

Slim 4 Life Scientific Abstracts:
When compared to placebo, all treatments had led to improvement in task performance. In guarana, the improvements were observed in “attention” tasks with little evidence of reduced accuracy. Both ginseng and ginseng/guarana had increased speed of attention tasks as well as memory task performance with insignificant evidence of modulated accuracy. Guarana had also led to substantial improvements in serial subtraction tasks. The results had given the first example of the psychoactive effects of guarana in humans, as well as the psychoactive properties of ginseng. Caffeine content had been waved as a potential contributing factor due to the low amount given to participants (9mg). 
Bitter orange extract (p-synephrine) by itself or when combined with other herbal ingredients, didn’t provide substantial adverse reactions as an increase in blood pressure, heart rate, alter electrocardiographic data, blood cell counts, serum chemistry, or urinalysis. Bitter orange by itself or when combined with other products had not displayed the ability to increase resting metabolic rate and energy expenditure. With bitter orange/ p-synephrine products, a modest raise in weight-loss was noted when administered for 6 to 12 weeks. It was determined that longer studies needed to be carried out in order to further access the safety and efficacy of the products. 
Meta-analysis of 3 controlled trials featuring participants with schizophrenia and 8 controlled trials (randomized) with patients who suffer from dementia. Ginkgo treatment had decreased positive symptoms in participants suffering from schizophrenia and boosted cognitive function in everyday life of those with dementia. No effects of ginkgo biloba (Gb) on the symptoms of schizophrenia were discovered. There was a lack of evidence which preventing a firm conclusion in regards to Gb’s effect in other neuropsychiatric disorders (depression, autism, attention-deficit hyperactivity disorder, anxiety, and addiction). The data had concluded that Gb for use in patients with dementia as well as an adjunctive therapy for patients with schizophrenia should be supported. 
Green Tea Leaves
There was a great variation in the peak levels of theaflavins and catechins, overall, the kinetic profile was the same (t1/2 = 25–44 min and 49–76 min). The average coefficient of variation in t1/2 was 23.4%. In addition to the parent theaflavin andc atechin peaks, there had been 5 peaks (not identified) in saliva after tea treatment. Hydrolysis of theaflavin gallates, most likely from salivary esterases, was noted in vivo and in vitro. The outcomes had suggested that tea leaves could be administered as a slow-release (and convenient) source of catechins and theaflavins as well as lending information of the possible effects that tea has on preventing tooth decay and oral cancer.
