Both Plenity and glucomannan based supplements work by absorbing water in the stomach and thickening it. With supplements like hourglass fit holding 50-60X it’s weight and Plenity claiming to hold 100X [1]. Our tests showed that it was more like 80, but that’s still good win.
That’s simple, it’s that Plenity only works on one way to assist weight loss, whereas some of the best commercial options (we’d recommend hourglass fit or instant knockout instead) have other ingredients that help with cravings.
Most notably 5HTP, which was previously only available via prescription[2], but is now commercially available as it is well documented to be safe and effective. 5HTP has been proven to actively effect brain chemistry to reduce desire for fatty, sugary and carb rich foods and has even been demonstrated whilst monitoring brain activity[3].
Or ingredients that help boost energy whilst dieting (amino acids, stimulants and vitamin complexes), that both cost less and don’t require a prescription.
But, that isn’t the biggest concern, Plenity is only licensed in the USA and Europe or the UK quite simply won’t allow it as it seems (although it isn’t well broadcast), may contain titanium oxide.

According
to the manufacturer, Plenity contains two active ingredients: cellulose and
citric acid. Cellulose is an indigestible plant fiber that makes up plant cell
walls. It is cheap and easily sourced. Citric acid is also a cheap food
compound sourced from citrus fruits and doesn’t really do anything to aid
weight loss, it’s likely just to help break down in the stomach.
Humans
cannot digest cellulose, so it simply passes through our system and is excreted
as waste (poop). It has no nutritional value, so diet pill manufacturers have
latched on to it as a cheap and convenient calorie-free thickening agent for
their products.
The Plenity
manufacturers claim that the cellulose and citric acid combine and react with
the fluid in the stomach to create a feeling of fullness and satiety, which
helps reduce hunger pangs and cravings.
We don't
disagree with this, but we know that there are already effective, natural
appetite suppressants such as Glucomannan that have far more research and
evidence of their effectiveness to back it up.
What
Plenity is heavily relying on for the effectiveness of their diet pills is what
they cleverly refer to as 'superabsorbent hydrogels'. This is nothing more than
mixing fiber with water in your stomach, making you feel full and lowering your
temptation to eat between meals.
But this is
no different to the many other much better-quality weight-loss supplements
currently on the market at a much more cost-effective price. Plus, there are
much safer alternatives to consume than a product containing inactive,
questionable ingredients such as titanium dioxide.
