Exposing The Claims Of Sensa Weight Loss Crystals

Someone is always trying to come up with the next big thing to help people lose weight effortlessly without dieting and exercise. A lot of individuals are quick to write off any such products as quick-fixes or gimmicks.

While it’s true a lot of these products are exactly that, I try and keep an open mind on what research may be able to add to the battle against obesity.

I think most experts will agree that a healthy diet and exercise are integral components behind any weight loss program.

I doubt there will ever be the “magic bullet” single pill or supplement to help people lose weight. None-the-less, when new products come out I try and review them with an open mind.

In today’s post we’re going to review Sensa Weight Loss Crystals and assess the validity of the product claims.

More after the jump…

The crystals, a product created by Dr. Alan Hirsch, are designed to be sprinkled on your food before you eat (much like salt). The end results is the compounds in the crystals are supposed to trigger you to eat less and therefore help you lose weight without even trying.

Heck, according to the ad below you can lose up to 30 lbs without dieting by simply using the crystals. Haven’t we seen similar claims like this before? Now let’s not rush to judgment just yet.

When the crystals first made it on the scene, it seemed like there may be legitimate research to back up the claims. Dr. Hirsch reported that his study had been peer reviewed by the Endocrine Society, in essence signifying that the Endocrine Society basically endorsed the results of his study.

Here’s the first red flag…the Endocrine Society reported in an ABC 20/20 interview that they were basically shocked at the promotional nature of Dr. Hirsch’s product because they did NOT endorse it.

In fact, I could find no published peer reviewed studies!

So while the Sensa website makes references to several studies on the product, it appears they’ve been done by independent laboratories and not been peer reviewed.

Does this mean the product doesn’t work?

No not necessarily, it just raises a red flag on claims of efficacy.

One of the main things I look for in research is published peer reviewed studies in credible medical or nutrition science journals. It’s just too easy to misinterpret results or come to the conclusions you were hoping for with independent laboratory studies. After all, who do you think is paying for the study?

One of the main problems I found with their initial study was the claim that inhaling odors prior to a meal can decrease how much is consumed. The issue I had was the study used extreme concentrations of the substance in the form of a nasal spray (not crystals).

Now why would the study use a nasal spray if they were testing the effects of the crystals?

In researching the Sensa Crystals, I read a lot of negative reviews from people who had actually tried them. Some were positive in all fairness, but the vote of public opinion seems to counter the claims on product effectiveness.

Some users report the crystals are not odorless or tasteless although I can’t confirm as I’ve not tested personally.  With the steep price tag of $89.95 it’s not an inexpensive product to experiment with.

Various users reported numerous negative side effects including such things as hives, dizziness, and loose bowels. Although this may be in isolated incidents, it’s enough to make you think twice about trying the product.

This is a perfect example where we can’t be persuaded just because a product claims it’s “clinically proven.”

What exactly does that mean? This could simply be that some independent laboratory came to the conclusions the manufacturer wanted them to in a non-peer reviewed study.

This is what makes things difficult for the consumer. Heck, maybe the compounds consumed in large doses in a nasal spray (as completed in their study) really did help people eat less. But what does that have to do with the crystals? It’s too much of a stretch to draw any clear correlations.

I did a little more digging on the company’s website and found the product ingredients.


This is a polysaccharide (aka long chain carbohydrate) that is commonly used as a food additive. Typically its main role is that of a thickener or filler in processed foods. It can also serve as a binding agent in pharmaceuticals, which is probably what it’s doing in the Sensa crystals.

Tricalcium Phosphate

Basically this is just a form of calcium. Not sure what impact that has or why it’s in the product. While research has shown that calcium plays a metabolic role in fat oxidation, there’s no correlation that I’m aware of on appetite suppression. After all that’s what we’re talking about here, right?


Ok, this one is easy. Silica is essentially sand and I’m guessing it’s included to give the crystals their hardness.

Natural and Artificial Flavors

That’s all it says, we have no idea what these flavors are. I guess they’re keeping that proprietary. Since the Sensa crystals are supposed to work by affecting taste/smell receptors it would be nice to know what they are.

To be completely honest I can’t draw much of conclusion at all from the product ingredients. There’s nothing listed from what I see that I’m aware of impacting sensory receptors with appetite.

So do these crystals really work?

It’s hard to say but my guess is not so much. There’s just not enough in credible research or consumer reviews to back up the product claims.

While I don’t see anything in the product ingredients that would be deemed as “unsafe” for consumption, the question becomes is it worth it to test?

Considering the expensive price tag I’d pass until I saw some better real world results or credible research.

The entire premise behind the product I have sort of an issue with anyways. Trying to trick your body into eating less isn’t necessarily the best of strategies. This is just another example of a weight loss product promoting the idea of eating all your favorite foods and still losing weight.

Just because you eat less pizza and pasta doesn’t automatically equate to the reduction of body fat. Let’s use common sense here for a minute.

Besides, you want to be eating whole foods that help control your appetite naturally. Foods rich in fiber do this along with natural fats which stimulate the production of the hormone leptin.

The body has its own means of helping you realize when “enough is enough.” We only screw up the signals when we consume a diet that is largely compromised of processed and refined foods.

Take in things like high fructose corn syrup, hydrogenated fats, artificial sweeteners, etc, and you short-circuit the normal regulation of neurotransmitters in your brain that impact appetite.

Bottom line in my book is you don’t need to sprinkle anything on your food or attempt to trick your body into eating less. Give your body plenty of live, natural foods and it will take care of this for you.

Because of all this, my final review on Sensa weight loss crystals is a thumbs down. Save your money to use on proven supplements or better yet more fresh fruits and vegetables.
