How Does Skinny Diva Raspberry Ketone Compare to Other Brands

Skinny Diva raspberry Ketone diet pillThe powerful weight loss benefits of raspberry ketone are well known, and the ingredient has become an increasingly common sight on the labels of weight loss formulation ever since the US TV personality, Dr. Oz, stood in front of a camera and referred to raspberry ketone as ‘a miracle in a bottle’.

The Protein Lab (based in the UK) are just one of many supplement manufactures who have jumped on the raspberry ketone bandwagon and produced a dedicated raspberry ketone blend. For reason or reasons unknown The Protein Lab seems to consider the blend is better suited for women, so they have placed the capsules in some nice pink and white bottles and are marketing it as part of their Skinny Diva range of products.

Advertised Benefits

Skinny Diva websiteNobody can accuse Skinny Diva for going overboard when it comes to promises, or making outlandish claims for their raspberry ketone blend. They keep it nice and simple:

  • Can aid weight loss
  • Can help decrease your Appetite

Breaking it down a little they explain that weight loss will be achieved because the capsules will help the user to ‘burn fat at a higher rate’.

Raspberry ketone has the power to do all of this, but some blends fail to fully utilize the power of the ingredient so it does not necessarily follow that all raspberry ketone products will live up to their manufacturer’s claims.

What is Raspberry Ketone and what Benefits can it Provide?

what does raspberry ketone doRaspberry ketone is a compound that is found in several fruits, including cranberries and blackberries, but the ingredient is usually sourced from raspberries.

Initial interest in raspberry ketone’s potential as a weight loss aid stems from laboratory tests conducted in 1995. Mice were fed unhealthy amounts of fat each day, while also being given regular doses of raspberry ketone, which appeared to prevent them from becoming obese. Despite the promising results, raspberry ketone remained a relatively unknown ingredient until Dr. Oz’ heard of the tests and decided to spread the word.

Although raspberry ketone is known to be an effective weight loss aid, scientists are still not sure how the results are achieved. It has been speculated the ingredients may alter lipid metabolism by stimulating white fat cells in a similar way to the capsaicin component found in red peppers. Other tests indicate raspberry ketone can enhance the metabolism and fire up thermogenic fat burning. The ingredient is also believed to suppress the appetite, but most experts agree further study is required.

Cost can be often become a factor with raspberry ketone products. Natural raspberry ketone is an expensive ingredient to produce so some manufacturers opt to use cheaper, synthetic forms of the ingredient instead. Such versions invariably lack the power of the true ingredient and their existence can make choosing an effective raspberry ketone supplement rather tricky because manufacturers rarely state which form of the ingredient they are using.

The Skinny Diva Raspberry Ketone Formulation

Each capsule weighs 450mg and contains 100mg of raspberry ketone. Which type of raspberry ketone is not specified.


Skinny Diva states one or two capsules should be taken each day, with meals. That would provide a maximum daily dose of 200mg. Many experts agree that 100mg to 300mg of raspberry ketone is the correct daily dosage required for optimum weight loss, so the dosage here is about right.

Side Effects and Health Issues

Raspberry ketone usage has not been linked to side effects, but pregnant and nursing mothers should always consult a doctor before commencing any form of supplementation. The same advice is offered to anyone who has existing or suspected health problems,

The Bottom Line – Do We Recommend

Skinny Diva Raspberry Ketone capsules are marketed on the premise that they can suppress the appetite and encourage fat burning. In theory the capsules should do just that. They contain a powerful ingredient and the inclusion rate is more than sufficient to produce the promised result—if the blend uses naturally sourced raspberry ketone.

The fact that Skinny Diva fails to state which form of the ingredient they are using would not be an issue if customer feedback was available to provide an indication of how well the product worked for past customers.

Some weight loss results are still probable. How good those results are likely to be is harder to say. In the end it’s a bit of a gamble, so consumers may wish to consider looking at alternative raspberry ketone products that are endorsed by the recommendations of past customers.

Skinny Diva Raspberry Ketone Purchasing Options

Sales of Skinny Diva products appear to be restricted to the Skinny Diva website, where customers can opt to pay £24.99 for a bottle of 60 Raspberry Ketone capsules or splash out an extra £5 for a bottle of 90 capsules.

The 90 capsule option is easily the better deal, but customers should be aware Skinny Diva does not offer a money back guarantee. Postage and handling charges of £3.99 are applied to orders placed by customers in the UK, and non-UK customers can expect to pay charges of £8.99, but charges are waived on all orders that total £50 or more.

Lifeplan 5:2 Fasting Diet Support Review – Customer feedback and comments

Lifeplan 52 fasting diet pill

Lifeplan 5:2 Diet Support capsules have been designed for use by people who are practicing Michael Mosley’s 5:2 Diet.

Although the 5:2 diet can produce some very tangible weight loss results it is hard diet to stick to and the hunger pangs associated with the regimen make it all too easy for 5:2 dieters to throw in the towel and write the diet off as being too hard.

Lifeplan claim their capsules make 5:2 dieting easier by suppressing the appetite.

At A Glance

Claims: To help reduce users get the best out of the 5:2 diet

Positives: Good concept with a good ingredient

Negatives: In our opinion this is not in the same league as the original product.

Read about the 5:2 Fast Formula

What is the 5:2 Diet?

the 5:2 dietThe 5:2 Diet is an intermittent fasting method. Dieters eat normally for five days out of every week, after which they must fast two days.

5:2 Diet creator, Dr. Brian Mosley, claims this form of on-off eating pattern is more compatible with the human metabolism than so called ‘normal eating patterns’ because it is similar to the kind of eating pattern early man was forced to endure. After a kill there would be days of plenty, but days of poor hunting were sure to follow and Mosley believes the human body was forced to adapt to such an irregular eating schedule.

Mosley’s theory makes sense, and many people have sustained very impressive weight losses by living the 5:2 way, but an ice-age has come and gone since early man walked the earth and present day men (and women) who try intermittent fasting often find their hunger pangs soon become a diet killer.

Two (500mg) capsules should be taken three times each day. Capsules should be taken with two glasses of water.

How the Capsules Work

glucomannan weight loss ingredientEach Lifeplan 5:2 Diet Support Capsule contains 500g of glucomannan. This is an increasingly popular appetite suppressing ingredient that often appears on the labels of weight loss formulations as ‘konjac’, ‘ konjac fibers’, or ‘konjac root’.

Glucomannan is sourced from the roots of a perennial plant found growing in Asia and is sometimes used in vegan recipes that require a suitable alternative to gelatin. The roots are very fibrous in nature and when the fibers come in contact with water they have the ability to swell up and increase their volume by up to 17 times. It is this ability that makes the ingredient such an effective appetite suppressing tool. It is also the reason why Lifeplan recommend the consumption of two glasses of water with each dose of capsules.

After the capsules have been swallowed the ingested water causes the Glucomannan fibers to swell. This creates a feeling of fullness in the stomach that remove the desire for food and effectively suppresses the appetite.

 Lifeplan 5:2 Diet Support Pros & Cons

Customer Feedback

At the time of this review customer feedback was in short supply. The available feedback is admittedly very good, but the amount available is far too limited to provide an accurate picture of product potential:

“Purchased this product to give me a bit of support on the 5:2 diet that I am on and it’s brilliant. I take these tablets as instructed and it does a great job of making me feel full. I will definitely buy these again as they are really helpful and worth the money. Superb!”

“I found this product really helped me cope with my fasting days and stopped me feeling really hungry. I did a little research and found it also help you loose weight not just help keep you feeling full.”

“I am on the 5:2 diet and find the fasting days quite hard to get through. I bought this product and it worked for me. You take the capsules before you eat and it helps you to feel full (but not uncomfortably). I have lost a stone so far on this diet, I love it!”


Lifeplan do not appear to offer a money back guarantee.

Side Effects & Health Issues

Lifeplan’s blend relies on just one ingredient—glucomannan—and it is not known to be problematic so the chances of side effects are unlikely. As with any form of supplementation though, pregnant and nursing mothers should seek medical advice before use. The same advice is offered to anyone who has any health issues or concerns.

Where To Buy – Pricing & Availability

Lifeplan 5:2 Diet Support capsules can be purchased from the manufacturer’s website and from a number of independent suppliers. The product can also be found listed on Amazon and eBay and British 5:2 dieters should also be able to find a few bottles sitting on the shelves of their local Holland and Barrett store. Prices vary from one supplier to the next and range from $15 to $25.

What Is Obethin and How Does It Work

Obethin website appetite suppressantsObethin is a dietary supplement that promotes weight loss through appetite suppression. It is composed of a mix of fibre that expands in the stomach.

The science is simple. Users take the capsules 30 minutes before meals, three times per day. The capsules contain a mix of fibres that expand in the stomach and take up space. With less space in the stomach, users will eat less during mealtime.

Taking in less food, and the accompanying calories, should result in weight loss. After 30 days of taking Obethin, users must take a break for 5 days to allow the intestines to clear themselves out and get rid of any residual viscous gel.

Although the principle is sound, users should ask if this product is really the best way to eat less. It comes down to finding out if this product works and if it’s worth it.

Key Ingredients

The fibres in Obethin are listed as Glucomannan, Xanthan gum, Sodium alginate and Flaxseed.

  • Glucomannan comes from the root of the Konjac plant, and is sometimes listed as Konjac. It is used for a variety of conditions, including weight loss, but has only proved to be effective for controlling cholesterol and blood sugar in diabetics.
  • Xanthan gum is a thickening agent that is formed by mixing fermented sugars with a particular bacterium. It has not been proven to aid weight loss, and instead is effective at lowering blood sugar and cholesterol in diabetics, and as a laxative.
  • Sodium alginate, also known as Algin, is a chemical derived from brown seaweeds. It is used as a food additive and binding agent and to treat conditions like high cholesterol and high blood pressure. There is no evidence that is an effective weight-loss aid.
  • Flax seed is the seed of the Linum usitatissimum plant. It is used as a food supplement and for the treatment of a variety of conditions like those that affect the gastrointestinal (GI) tract and the heart and blood vessels. It has been shown to be effective in lowering cholesterol and lowering blood sugar in some diabetics. It has not been shown to be effective in weight-loss.

Obethin Possible Side Effects

Always consult your healthcare professional before starting any dietary supplement.  Pregnant or nursing women should not take this product.

Xanthan gum can cause gas and bloating and interacts with diabetes medications. It should not be used by people with conditions like appendicitis, vomiting, nausea and faecal impaction because of its performance as a bulk-forming laxative.

Sodium alginate is a thick gel that can interfere with medication taken orally. It sticks to them in the stomach and intestines and can affect how much medicine the body absorbs. Users should take it at least one hour after taking oral meds.

Flaxseed is generally considered safe as a dietary supplement when taken for up to 12 weeks. Higher doses and longer consumption can cause problems. The most common side effects involve the GI tract and include gas, bloating or stomach ache.

Bottom Line… Is It Recommended

Short answer: No.  While Obethin does win points for taking a sensible versus sensational approach to weight loss, it’s just not necessary nor is it worth it. Consumers should remember that Obethin works by basically creating a bulky, sticky gel in your stomach and intestines that can build up. That’s why they need to stop taking the capsules for 5 days after every 30 days of use.

The thought of having to expel this bulky gel is not pleasant, and can be totally avoided by going the natural route. Users can accomplish the same result – consuming less – by reducing their portion size and increasing the natural fibre in their diet using low-calorie options like apples. Increasing naturally occurring dietary fibre also has the benefit of adding the vitamins and minerals that occur in the food.

Processed food does not contain much fibre, and does contain lots of sodium, fats and sugars. A diet high in natural fibre will not contain much processed food, which will also get rid of the salt, oils and sugars that they add. Finally, a bottle of 120 capsules (approximately a 30 day supply) costs nearly 30 GBP. That money would be better spent buying something with a proven track record of success
