BeSlim Review - 13 Things You Need to Know
If you want the bottom line on BeSlim, give me just two minutes of your time. Our research team put an intense focus on the ingredients, potential side effects and clinical studies backing the claims. Additionally, we examined hundreds of user comments and reviews. Lastly, we gathered the facts to give you the details.
What is BeSlim?
BeSlim is a weight loss supplement. This product was created by the supplement manufacturer Medifast through the TSFL BeSlim program. The program takes around 30 days to start seeing results.
Medifast claims that users of BeSlim will lose weight and improve their general physical fitness after a minimum of 30 days in the BeSlim program.
BeSlim was released in 2002 and remains one of Medifast’s most popular products to date. Their parent company, Take Shape for Life or TSFL has been in the supplement market since the early 80’s. They have a full range of supplements and fat burners in addition to their BeSlim line.
There are numerous different products in the BeSlim Line. These include cleansing teas, meal replacements/protein powders, capsule supplements and more. While each product contributes differently to weight loss and physical fitness, they all share some common ingredients.
According to Medifast all of the ingredients included in BeSlim are organic and non-GMO. BeSlim works by boosting your endurance during workouts while kick-starting your metabolic rate. A higher metabolism leads to more fat loss through thermogenic effects in your body.
The main active ingredient in BeSlim is Camellia Sinensis leaves aka green tea. Camellia Sinensis has two complimentary fat burning effects on your body. The green tea ramps up your ability to go harder, for longer, during your workouts.
In addition to this energy boost, green tea also raises your body temperature creating a phenomenon known as thermogenesis. When your body temp is raised, your body goes into fat burning mode. This is because your body needs more heat and energy to survive in colder weather.
Fat burners like BeSlim and other products on the market take advantage of this phenomenon. Their goal is to get your body temperature to a safe, but high temperature to maximize fat burning.
Raspberry Ketones are an interesting addition to BeSlim. Your body produces ketones in your liver. Your body drastically increases the number of ketones created when your body goes into starvation or fat burning mode. Ketones put the keto in the ketogenic diet.
L-Carnitine seems to be the last of the active ingredients that contribute to fat burning. This helps prime your muscles for growth while restricting the amount of fat that is created in your body. L-Carnitine also has a positive effect on hair and skin quality. 
Does BeSlim Work?
BeSlim supplements will be effective in certain situations. From their marketing, it seems like this product is aimed almost exclusively at women. The formula and active ingredients included in BeSlim also allude towards this fact.
This product will work on both genders, but it seems to be designed to maximize women’s weight loss- which can be radically different than weight loss for men. Women tend to carry higher fat percentages in their body due to how fat is distributed through the body.
The green tea extract is the main active ingredient in BeSlim. All of the other active ingredients in this product are designed to work around and with the GTE.
With the vast majority of fat burners on the market advertising, some thermogenic effect BeSlim is not unique in that regard. The goal of TSFL BeSlim is to create the most fat loss using thermogenesis.
The issue with BeSlim is the fact that it is not a very strong fat burner. While it will have some effect on weight loss, it is very likely that the product will not hold up to strong scrutiny. BeSlim simply does not have enough effective active ingredients to be considered a top-tier product.
Stronger fat burners will create a better thermogenic effect. This comes with the downside of more side effects- irritability, lack of sleep, etc. These side effects tend to diminish with time alongside the fat burning effect. When you use a supplement like BeSlim, you are not maximizing your endurance and gains.
The bottom line is that this supplement works well for those who are just starting out on a workout routine. However, if you are trying to beat a plateau or hit the gym hard, you will be better served by other products. 
BeSlim Benefits and Results
Results gained from BeSlim will likely be moderate for the vast majority of users. Unfortunately, I was not able to find any scientific studies that address the specific proprietary blend of substances used by BeSlim.
Luckily, there are many studies on the efficacy of green tea, ketones, and many of the other active ingredients in this product. Green tea will have a substantial effect on weight loss when compared with a control placebo. The reason for this is the caffeine in the tea.
The caffeine increases your heart rate and at the same time creates a need in your body for more fuel to make energy. This leads to weight loss since your body converts fat to energy. Caffeine has been shown to be an effective weight loss aid and you will see benefits from this product.
There is always a but…and the but for this product is the intensity. Since there are not many active ingredients in BeSlim other than caffeine it might be better (and cheaper) to simply drink a cup of coffee and a multivitamin with your morning workout. You would be getting essentially the same substances at a fraction of the price. 
Details on BeSlim and Weight Loss
BeSlim Medifast claims that their product works by taking advantage of a synergistic effect that happens in the body when particular substances are mixed in a proprietary blend. There are no scientific studies that have been done on BeSlim- but we can deduce the effectiveness of this product from the active ingredients.
There will be some weight loss benefits from taking BeSlim but do not expect something revolutionary. There may be small effects from taking a caffeine supplement with your workout.
If you are serious about weight loss, it would be prudent to consider supplements other than BeSlim Medifast. Unless you have a heart condition or something else preventing you from taking a stronger fat burner, you may want to take a look at another supplement that has more/stronger active ingredients. 
How to Use (Take) BeSlim
BeSlim has comprised of 2-4 capsules taken daily. Medifast recommends that you start by taking one capsule with your morning meal. Preferably after your meal, you should also engage in physical activity.
When you have your mid-day meal take another capsule. If you take the capsule too late in the day it will contribute to side effects like sleeplessness- so be aware. After you have taken BeSlim for about a week, you can double your dosage to 2-4 capsules per day.
Since you are chasing a thermogenic effect when taking BeSlim, you can try to take it on an empty stomach in the morning- right before you workout. When you do cardio exercise on an empty stomach, your body will automatically tap into your natural fat stores.
These fat stores are used by your body to create the energy needed to work out. Taking BeSlim to boost this effect is a good way to increase your fat burning ability. In addition to the thermogenic effect, this supplement will also drastically boost your energy levels when working out. 
BeSlim Product Warnings
This product should be avoided by a couple of key groups. If you have a heart condition or high blood pressure stay away from BeSlim unless you have consulted with a physician.
Pregnant as well as nursing mothers should also avoid taking BeSlim. The supplements included in this product are not meant for infants.
BeSlim will contribute to restlessness, higher heart rate, nervousness, and a whole host of other issues that come with taking stimulants. If you have any serious medical condition, it is imperative that you stay away from this supplement.
Is BeSlim Safe?
As far as being a fat burner goes BeSlim safe. The product has been on the market for more than 16 years now. The manufacturer behind BeSlim is also a prominent supplier in the nutritional industry. Medifast has a pretty solid reputation in the community so you should be able to give them the benefit of the doubt.
If you have any preexisting conditions like high blood pressure, anxiety, or are expecting/nursing a child this product is likely not safe. Always consult a physician before taking a new supplement if you have one of these conditions. 
BeSlim Side Effects
Some side effects from BeSlim ingredients may include:
- Trouble Sleeping
- Heart Palpitations
- Shaking Legs
- Excess Energy
The BeSlim side effects are relatively mild compared to the competition. This is because BeSlim is not as strong as many of the other supplements in the marketplace.
A good rule of thumb is – the stronger the supplement, the stronger the side effects. You can avoid the vast majority of BeSlim side effects by taking the correct dose at the correct time.
Going over your dose or taking the supplement too late will greatly contribute to issues with the capsules. As long as you follow the general instructions, you should be fine. If you are having trouble while following instructions drop your dose down. This will help you find out if you are allergic to something in the capsules. 
Through an exhaustive search of various blogs and online searches, we found no lawsuits that involved BeSlim.
There are many other fat burners on the marketed that are aimed at this demographic. Since every supplement is different make sure you choose one that is aimed towards your fitness goals.
Weight loss supplements are going to be different than muscle building supplements, for example. When it comes down to it, you want to find a product that works for your body and fitness level.
This product is among the most popular fat loss supplements aimed towards active women. Instead of just being a fat burner, Instant Knockout aims to increase workout duration and intensity.
Instant Knockout is much lower in caffeine when compared to BeSlim. The manufacturer of Instant Knockout claims this will reduce the jittery feeling that comes with many other weight supplements.
The three main active ingredients in Instant Knockout are:
- Coffee extract
- Cayenne pepper
- Green tea extract
It stands to reason that the manufacturer of this product is looking to create a thermogenic effect, much like BeSlim. 
Muscletech Hydroxycut Hardcore Next Gen
This supplement is considerably more hardcore than BeSlim. Muscletech Hydroxycut Hardcore Next Gen is meant for people who are serious about their workouts and cutting before shows/athletic performances. This stack will give you much greater gains than BeSlim results.
While the effects of this supplement are considerably stronger than BeSlim weight loss effects there is also a downside. With greater effectiveness comes more side effects. Before committing to a supplement like Muscletech Hydroxycut Hardcore Next Gen, you should dip your toes in by trying one capsule.
If the pill agrees with your body- continue ahead. Starting small and working your way up will help you if something in your body is not happy about this pill in particular. It will also make allergic reactions much less due to the smaller amount of the supplement in your bloodstream.
The main active ingredient in Hardcore Next Gen is caffeine anhydrous. This additive is proving extremely popular in the bodybuilding world. This product also comes with:
The combination of all of these substances in one pill makes for a seriously amped stack. 
RSP Nutrition Quadralean Thermogenic
This product is the solid middle ground between Hydroxycut and BeSlim. While it is not going to jack you up like Hydroxycut, it will have a performance and thermogenic boosting effect that is stronger than the BeSlim results.
The manufacturer uses many of the same additives, like Yohimbe, Skullcap, and caffeine. However, the doses have been tweaked compared to the two supplements that were just mentioned. RSP Nutrition tried to build a middle of the road supplement and they succeeded.
If you find yourself at an impasse when it comes to deciding between BeSlim and Hydroxycut this is a fantastic solution. Simply go for the moderate stack and dosage and you will likely reach your goals quickly. 
The Bottom Line on TSFL BeSlim
So, should you whip out your credit card and be part of the BeSlim club? Well, we appreciate that all of these food products are available directly through the official website. Also, it’s nice to see that company background information and contact details are provided. However, we have some doubts about this program because it’s not really backed by any solid science. Furthermore, we’re concerned about the high cost and less-than-savory taste.
If you’d really like to shed some pounds, then we encourage you to select a diet program or product that does not have an unpleasant taste, will not break your bank account, is easy to use anywhere and gives you plenty of bang for your buck.
