Okinawa Flat Belly Tonic is a weight loss supplement manufactured by Vitalina. This manufacturer made a probiotic weight loss supplement called BioFit which we previously reviewed, and it was one of the worst-formulated supplements we’ve come across.

There are several versions of a product with this same name sold, but we’re choosing to review the one manufactured by Vitalina, available on Amazon, as it has the most reviews and seems to be the original.

In this article we’ll review the ingredients in Okinawa Flat Belly Tonic based on published medical research to determine if it’s likely to be effective for weight loss.

Ingredient Review

Okinawa Flat Belly Tonic ingredients

The first thing a consumer notices when browsing the Okinawa Flat Belly Tonic Amazon product listing is that there is no image with the Supplement Facts label. The only product image is a single image of the front of the bottle.

This clearly violates Amazon’s dietary supplement guidelines, which state that dietary supplement images must show all sides of the product label including the ingredients list.

It’s also a red flag of a low-quality brand that doesn't care at all about their consumers. To fail to clearly publish the ingredient label in your product images, when nearly every supplement brand does so, is a sign of clear incompetence in our opinion. This information is critical for consumers to make informed purchase decisions.

The ingredients are listed in the product description.

The only three active ingredients in Okinawa Flat Belly Tonic are ketone salts: magnesium beta-hydroxybutyrate, calcium beta-hydroxybutyrate and sodium beta-hydroxybutyrate.

It’s important to point out that this product has no dosage listed for the active ingredients, which is extremely unprofessional and dangerous. Without a published dose of each active ingredient, there is no way for consumers or researchers like us to determine if the dose is safe.

Taking exogenous ketones can induce ketosis irrespective of diet, and the thought process behind most supplements containing beta-hydroxybutyrate (BHB) is that it will cause weight loss due to this influence of ketosis in the body.

Okinawa Flat Belly Tonic contains four inactive ingredients (magnesium stearate, rice flour, silicon dioxide, gelatin) which are all standard supplement filler ingredients. These are safe and non-toxic and should be no concern to consumers. It is notable that the brand spells silicon dioxide incorrectly (as “silicone dioxide”); another sign of a low-quality brand with no competent scientists.

Does It Work For Weight Loss?

Since the only active ingredients in Okinawa Flat Belly Tonic are ketone salts, we can review the medical literature on these compounds to see if there’s any proof they’re effective for weight loss.

We found one animal study suggesting ketone salts may be effective for weight loss, but the results in humans have been unimpressive. The linked animal study found that the supplemental ketogenic agents helped induce weight loss, but it was a poorly designed study with no control group.

The researchers of the study even noted that a ketogenic supplement called R/S 1,3-butanediol acetoacetate diester was the most effective, and significantly more effective than BHB.

A more recent human clinical trial compared the effects of a hypocaloric (fewer calories than maintenance) and ketogenic diet, with and without ketone salt supplementation, on weight loss. The study authors concluded that weight loss was “not further impacted by administration of an exogenous BHB-salt”.

It doesn’t appear that there are any medical trials testing the effects of a ketone salt supplement on a human population for weight loss, so we will conclude that this supplement is entirely ineffective.

Even if there were research suggesting that exogenous ketone salts could help with weight loss, Vitalina doesn’t publish the dosage of their active ingredients, so it would be impossible to determine if the supplement was accurately dosed.

Okinawa Flat Belly Tonic Side Effects

Exogenous ketones do cause side effects in some patients. A clinical trial of ketone salts as a supplement for healthy adults caused 1 of the 6 volunteers to drop out due to severe vomiting, nausea and abdominal pain. This was a small trial, but similar reports have been documented in other studies

We believe the risk of side effects is higher in Okinawa Flat Belly Tonic than other ketone salt formulations because the dose is not published, which means the dose could be dangerously high and we would have no idea.

Natural Weight Loss Alternative

We believe that patients interested in losing weight should speak to their doctor about intermittent fasting as a lifestyle modification that’s clinically effective.

A medical review on intermittent fasting published in the Canadian Family Physician journal analyzed the results of 27 different individual trials on intermittent fasting for weight loss. In all 27 trials the participants lost weight on average. The range of average weight loss spanned from 0.8% to 13% of baseline body weight.

The researchers also noted secondary benefits like reduced blood pressure and reduced insulin levels, although it’s impossible to attribute those effects to intermittent fasting because reduced weight itself may have caused those changes.

Intermittent fasting typically requires fasting for 16 hours of the day, and the standard caloric intake in the remaining 8 hours. Patients can drink water, coffee and tea during the fasting hours as these are non-caloric.

The reason intermittent fasting is proposed to be so effective for weight loss is because we burn fat rather than glucose when insulin levels drop, and extended periods without eating cause insulin levels to drop as documented by the above-linked study.

It’s important that patients talk to their doctors before starting an intermittent fasting routine, because it may not be safe for some patient populations like diabetics.

Conclusion

Okinawa Flat Belly Tonic is a poorly-formulated weight loss supplement and we recommend you avoid it. There is no proof that it’s effective, and it contains no published dosages on its Amazon label which violates Amazon’s guidelines and is dangerous to consumers.

Vitalina appears to be a very low quality supplement manufacturer with poor business ethics, and we recommend that consumers avoid all of their products, as the two supplements of theirs we’ve reviewed (BioFit and Okinawa Flat Belly Tonic) had so many issues that we don’t trust the brand at all.

We find the research on ketone salts for weight loss to be lacking generally, and believe that an intermittent fasting diet would be a free way for some patients to achieve weight loss outcomes superior to that which could be achieved with this supplement.
