As the name suggests, Body & Fit Sustained Release Fat Burner is a natural fat burning supplement distributed by Body & Fit.

The company says its slow release fat burner is unique and “one of a kind.” However, although the formulation may differ from the alternative options, slow-release fat burners are nothing new.

In this review, I’m going to take a closer look at the ingredients in Body & Fit Sustained Release Fat Burner and explain the things they can do. I will also share some comments from previous users and, towards, the end of the review, will look at the cost of using Body & Fit Sustained Release Fat Burner and its ability to provide good value for money.

Although this Body & Fit supplement has possible potential in several areas, it’s lacking in others. There are better options to choose and if, after reading this review, you decide Body & Fit Sustained Release Fat Burner is not an option you wish to try, don’t worry. I’m going to suggest a better fat burner you can use instead and, unlike Body & Fit Sustained Release Fat Burner, it has a money-back guarantee.


Who Makes Body & Fit Sustained Release Fat Burner?

This is part of a range of sports supplements distributed by Body & Fit Sportsnutrition B.V. It’s a Dutch company based in Heerenveen, the Netherlands.

Body & Fit has been trading since 1995 and has the goal of inspiring people to live fitter and healthier lives.

In addition to distributing its own range of supplements, Body & Fit also sells health and wellness products manufactured by other respected companies including Optimum Nutrition and Slimfast.

The company website also provides options to buy training accessories such as yoga mats, hoodies, and Body & Fit T-shirts.

Although it’s based in the Netherlands, Body & Fit distributes its products all over Europe and even has an English language version of its website for customers in the UK.

If you visit the site from the UK, the site will automatically detect your location, render all the information in the appropriate language, and provide prices in pound sterling instead of euros.

Although Body & Fit is a reputable company, one thing lets it down – it does not back its supplements with a money-back guarantee.


Promised Benefits

Body & Fit doesn’t make a lot of exaggerated claims for its product. As is the norm with this company, it simply tells it like it is without any BS or hype.

  • Sustained release
  • Provides zinc to contribute to normal fat metabolism
  • Contains 200 mg of caffeine per dose.


How to Use Body & Fit Sustained Release Fat Burner

The dose is two capsules, taken once per day, with a full glass of water.

You have the option of taking the capsules shortly after your breakfast or 30 minutes before your workout.

The capsules provide a reasonably high dose of caffeine so, if you take them before your workout, they should give you some extra energy to train.

However, if you normally train in the evening, you may want to adjust your routine so it’s possible to take the capsules before your workout and still have a five-hour gap before going to bed.

If you don’t it’s possible the caffeine in Body & Fit Sustained Release Fat Burner may interfere with your ability to sleep.


Who Can Use Body & Fit Sustained Release Fat Burner?

The product appears to be aimed at most men and women who are seeking something to help them to lose weight.

However, Body & Fit makes it clear its sustained release fat burner is not intended for children or women who are pregnant or nursing a child.

Sustained-release supplements tend to be especially useful for people who have hectic routines or find it difficult to remember to take pills. In this case, you only need to remember to take a dose after breakfast or before training and that’s it. Job done. It’s an easy product to fit into your daily routine.


Things to Bear in Mind

Like other weight management products, Body & Fit Sustained Release Fat Burner is a supplement. It’s important to understand what a supplement is and never to see any form of supplement as a magic pill.

The word “supplement” refers to something you get or use in addition to something else. For instance, Some people work two jobs to “supplement” their income.

Diet pills and other weight loss supplements, supplement the efforts you are already making by controlling your diet.

In this case, it’s important not to see Body & Fit Sustained Release Fat Burner as a product that provides an excuse not to try and eat healthy foods. The pills will work best if you use them alongside a healthy diet that contains nutritious foods that are low in fat and sugar.

Body & Fit Sustained Release Fat Burner Ingredient Potential

Okay. This is a very important part of the review. It’s where we take a look at the ingredients and see what they can do.


Acetyl L-carnitine (250 mg)

Acetyl L-carnitine provides L-Carnitine. It’s an amino acid-like chemical that helps the body convert fat into energy. It’s not a particularly common diet pill ingredient but it does have value.

Research suggests supplements that provide L-Carnitine L-Tartrate may also help speed up muscle recovery after exercise. So its presence here may make Body & Fit Sustained Release Fat Burner a little more attractive if you are someone who likes to train.


​Ashwagandha extract (250 mg)

Ashwagandha is a respected adaptogen herb and the dose here is okay.

Herbs of this type are good for reducing anxiety and stress. This one is also a popular testosterone booster. It’s unlikely to directly help with weight loss but its ability to increase testosterone may still be beneficial. In addition to supporting muscle growth, testosterone also helps the body to burn its fat.


Caffeine (200 mg)

Caffeine is a stimulant. It provides energy. That makes it useful for fighting diet-related fatigue. It’s also good for boosting concentration and helping to blow mental cobwebs away.

Caffeine suppresses appetite as well but the effect is very mild. It has far greater potential as a fat burner. Research proves its ability to increase energy expenditure and help you to burn extra fat.

The dose provided here is the equivalent of a couple of cups of standard coffee. That’s slightly less than you’d get by drinking three espressos (77 mg of caffeine per shot).

If you are generally okay drinking a couple of coffees back to back, you should be able to use this supplement without any negative issues.

However, if you are normally overly sensitive to caffeine, you may want to forget about Body & Fit Sustained Release Fat Burner and choose a stimulant-free fat burner instead.

Choline (82.5 mg)

There’s a lack of evidence to support using choline for fat burning but one study, involving female martial artists, suggests it may support rapid weight loss without reducing physical strength.


​Ginger extract 20:1 (50 mg)

GingerGinger is not a popular diet pill ingredient. Nevertheless, it may have the potential to support weight loss and this is a heftier dose than it appears.

Body & Fit is using a 20:1 extract. That means it is meant to have 20 times normal potency. It’s impossible to verify the claims made for extracts like these but, if the claim holds good, the 50 mg extract Body & Fit is using will be the equivalent of a full gram of standard ginger root extract.

The results of a 12-week study conducted on obese women (aged 18-45) show ginger was effective in supporting reductions in body weight. However, the women in the study were getting two grams of ginger per day. Even if Body & Fits’ extract has the necessary potency, its slow release fat burner will still be providing only half that amount per day.


​BioPerine (5 mg)

Bioperine is a popular diet pill ingredient. It’s a black pepper extract that boasts an unusually high level of piperine.

Piperine is the alkaloid that gives black pepper its smell. Standard black pepper extracts are generally only 7-8% piperine. BioPerine is standardised for potency and strength. It’s at least 95% piperine.

Why is this important? Let me explain. Piperine boosts the absorption of other ingredients, helping you to absorb them faster and more easily.

I’m not sure how this makes it a good fit for a slow-release supplement like this one though. It would seem to work against the desired effect.


​B Vitamin Complex

Body & Fit Sustained Release Fat Burner contains five B vitamins. Each one offers individual benefits and their presence here will certainly help support good health.

One of the things all B vitamins do is help your body extract energy from the food you eat. That’s why they are present in so many energy drink formulas. It’s also why they are common additions to sports supplements.

Some stimulant-free diet pills use B vitamins to compensate for the lack of caffeine. Others have both.


​Chromium (40 µg)

Chromium is a popular diet pill ingredient. It regulates blood sugar and insulin. By doing this, it can prevent the blood sugar spikes and dips that can trigger sugar cravings.


​Iodine (150 µg)

Iodine is a valid diet pill ingredient but its presence in Body & Fit Sustained Release Fat Burner or any other supplement will only offer value to people who are iodine deficient.

Your thyroid gland needs adequate iodine to produce the thyroxine and other “T-hormones” that govern metabolism.

When your diet fails to provide sufficient iodine, your metabolism may slow down. This will make you more prone to weight gain. It will also make losing weight more difficult.

Zinc (5 mg)

Zinc gets the most attention for its ability to boost testosterone and support efficient immune function. Nevertheless, some research suggests zinc can also support fat loss by controlling appetite and insulin resistance.


Body & Fit Sustained Release Fat Burner Customer Reviews

At the time of this review, the Body & Fit website was the only source of customer feed.back That’s not ideal. I would prefer to see customer reviews from a less biased source.

However, although many of the reviews are positive, there are enough negative experiences posted to make me believe there has been no tampering and that the information the site provides is accurate rather than hand-picked.

Unfortunately, the positive reviews are lacking in detail. One lady says the pills helped control her appetite, and a male customer says he lost 20 kilos in 12 weeks, but most customers just say that they are happy the pills work.

Most of the negative reviews are not from people claiming Body & Fit Sustained Release Fat Burner does not work. They are from people complaining the pills are too big to swallow and/or saying they don’t like the taste or smell.

Known Side Effects

Customer reviews don’t mention side effects but the formulation contains caffeine. The dose is not unreasonably high but, although the average person should be able to use this supplement without issues, people who are sensitive to caffeine may experience jitters, headaches, nausea, and/or similar caffeine-related side effects.


Health Considerations

If you are pregnant or nursing a child, please don’t take any kind of supplement without getting clearance from your doctor first.

If you have an existing medical condition of any kind at all, it would also be unwise to use supplements without checking with your doctor first.

Certain supplement ingredients can present interaction issues when combined with medication. It doesn’t matter if the medication has been prescribed by a doctor, a dentist, or another medical professional. If you are taking medication, don’t use it with supplements without asking a doctor first.

Where to Buy Body & Fit Sustained Release Fat Burner

At the time of this review, Body & Fit appears to be mainly distributing its sustained release fat burning formulation via the official site. It may later become available via and other Dutch or European sites but, if you are reading this review from the UK, the only option will be to buy the product via the Body & Fit website.

Each box provides a 30-day supply of capsules. The original price is £36.99 but, at the time of this review, the cost of buying Body & Fit Sustained Release Fat Burner had been reduced to £22.19.

Shipping is extra but that’s not a problem. With such a low price, Body & Fit would not be able to afford to waive the postage and packaging costs.


Does Body & Fit Offer a Money-Back Guarantee?

Unfortunately, Body & Fit does not provide a money-back guarantee.


Body & Fit Sustained Release Fat Burner Review: Diet Pill Ninja Conclusion

The Diet Pill Ninja: Honorable Diet Pill ReviewsBody & Fit Sustained Release Fat Burner is a relatively cheap weight management supplement and, due to the caffeine and B vitamins, it should provide most people with a reasonable energy boost. However, in all probability, it will offer more benefits as a performance booster than a weight loss aid. Having said that, it should be good for helping you to burn some extra calories while training.

As for providing a sustained release of benefits, that’s a nice idea but there is no way to check on the science. Body & Fit obviously believes/hopes its pills will do this, but it doesn’t provide any evidence that shows they can do so.

Due to the presence of caffeine, the pills should certainly provide a metabolism boost but their ability to do this will be limited in people who have a high tolerance to caffeine. It will also reduce as they become accustomed to it.

The formulation is also held back by the lack of any good natural appetite suppressants. Hunger is one of the most frustrating things about dieting, so this is a very big failing.

Iodine and zinc offer theoretical weight loss benefits but probably only to people whose diets fail to provide enough of these two important nutrients.

So, although Body & Fit Sustained Release Fat Burner is a reasonably cheap weight management supplement to buy, I cannot recommend it. I don’t feel it will offer the average person good value for money and it lacks a money-back guarantee.


Capsiplex: A Good Alternative to Body & Fit Sustained Release Fat Burner

Box of Capsiplex Fat BurnerIf you need a good diet pill to help you to lose weight, consider using Capsiplex instead. It costs a little more than Body & Fit Sustained Release Fat Burner but it’s a much better product and when you order two boxes, you get a third one for free, making the cost of using Capsiplex much cheaper than using Body & Fit Sustained Release Fat Burner.

The Capsiplex formulation provides a potent capsicum extract that suppresses hunger and boosts your metabolism to help you burn extra fat.

Like Body & Fit Sustained Release Fat Burner. Capsiplex is a one dose a day formulation and it boasts its own slow-release technology that allows the pills to be gentle on your stomach but hard on your fat.

Even if you decide not to take advantage of the opportunity to get three boxes of Capsiplex for the price of two, the overall cost of using the product will still be cheaper because the manufacturer does not add any shipping charges and, in these post-Brexit days, there is no need to worry about any import tax because the pills are dispatched from within the UK. Capsiplex also has a 60-day money-back guarantee, so you can buy it and try it with nothing to lose.
