You’ll be pleased to
hear that the Zotrim® formula
(included in Fibretrim™) has
tons of proof to back it up!

"Zotrim is the only non-medical proven weight loss product on the market to be confirmed as a weight loss aid with sound scientific proof."

We are extremely proud of the success of Zotrim.  It’s because of that and the results of one of our studies that we decided to create Fibretrim.

We knew that the Zotrim formulation was proven to be effective and with 10 million customers, we also knew it was popular.  But from the results of this study, we knew we could improve the formula.

So we created Fibretrim which is simply the proven Zotrim formula, with the addition of Inulin.  Not only does the Inulin make the formula more powerful, it also has a multitude of health benefits on its own.  Our formula is unique, you can read more about our ingredients here.

The Zotrim® formula has a massive amount of proof to back up its claims . . .

58 young women who were of normal weight or slightly overweight attended an eating clinic.

They were given either three Zotrim tablets or placebo tablets made of lactose fifteen minutes before a fixed calorie breakfast and again before an ad-libitum lunch consisting of twelve high and low fat savoury and sweet foods. Food intake (gram and calories) and food choice were carefully monitored.

Hunger and desire to eat were monitored by visual analogue scales.

"Robust results which help explain the weight loss results in previous research".

Placebo-controlled study on weight loss

Conducted over a 45 day period, 47 overweight subjects aged between 20 and 60 were given Zotrim or a placebo to assess the effects Zotrim’s formulation had on their weight loss.

Split into groups consisting of those on Zotrim and those taking a placebo capsule containing lactose, they were instructed to take their capsules 3 times a day before every meal.

Designed to examine Zotrim’s ability to help consumers maintain their weight loss, 22 of the 24 subjects who took Zotrim formula in the above study by Torben Andersen, were provided with a 12 month supply of Zotrim.  Weighed monthly, they were instructed to take Zotrim if they started to put weight back on:

Consumer study on weight loss and eating behaviour

Performed using 50 UK adults who wished to lose weight, they were provided with Zotrim tablets and were instructed to take 2 tablets, 3 times a day before every meal.

Over the course of a month, they had to complete questionnaires based on their progress for the time leading to day 7, 14 and 28.

  • 50% reported to have eaten less than usual
  • 66% reported to have snacked less between meals

Gastric emptying rate study

In order to assess the connection between stomach fullness and gastric emptying, 7 subjects - who had previously fasted prior to the study – were given Zotrim formulation on one occasion and placebo capsules of lactose on another occasion in a double blinded study.

Asked to drink 20ml of apple juice followed 15 minutes later by a further 400ml, their gastric volume was monitored through ultrasound measurement every 10 minutes until their stomachs had emptied.

  • Zotrim: average gastric emptying 58 minutes
  • Placebo: average gastric emptying 38 minutes

Time to fullness study

The time needed to achieve gastric fullness was investigated using 20 subjects who were asked to take 2 tablets of the Zotrim formulation or 2 of the lactose placebo capsules.

Instructed to take them 10-15 minutes before every main meal, whilst they ate they had to monitor the length of time it took for them to feel full.  This figure was then compared to their other meals.

  • Zotrim: Average combined time to gastric fullness over 3 meals: 35 minutes
  • Placebo: Average combined time to gastric fullness over 3 meals: 61 minutes

Effect of TV Viewing and Zotrim on snacking

Identified as a key influencing factor behind our eating choices and weight management, the effect of TV viewing and Zotrim on subjects energy intake was explored with the help of 11 healthy adults.

Split into 2 groups, subjects were required to either take 2 Zotrim tablets or 2 placebo tablets in the morning as well as before lunch. Two hours after eating, subjects were then exposed to a TV video or a blank screen were given the additional option of either reading/studying or having unlimited access to sugary foods.

Their total energy intake during lunch and snacking was then measured. 

  • Zotrim: energy intake dramatically reduced when watching TV
  • Placebo: energy intakes was significantly higher when subjects watched TV than when they chose not to

Weight Loss Study

During a customer intervention, 61 overweight women took Zotrim for a period of 4 weeks.  From here their hunger and eating patterns were recorded, whilst their weight loss and waist measurements were also taken at the beginning of the study, during week 2 and lastly on week 4.

  • Subjects consistently felt fuller for longer
  • Changes witnessed through Zotrim over these 4 weeks compared favourably with long term weight management therapies

What did the BBC say about Zotrim®?

"The only company which could show a clear link between weight loss and their product was a herbal diet pill, called Zotrim, which makes you feel full.

Their research had been published in a reputable journal and conducted with a control group to compare any placebo effect."  Professor Lesley Regan

Zotrim is the only non-medical proven weight loss product on the market to be confirmed as a “weight loss aid with sound scientific proof."

Cost effective, 100% natural and the only natural diet pill to provide evidence of weight loss on BBC2’s Professor Regan’s Diet Clinic (16th April 2009).

What did Professor Lesley Regan say
about our competitors?

Professor Regan stated that Zotrim is the more superior dietary supplement when compared to other products on the market, many of which do not provide sound evidence of actual weight loss.

The Pink Patch said "no evidence of its effectiveness actually exists", while Formoline L112 said they couldn't provide a copy as their research hasn't ever been published.

Lipobind sent research results showing the tablets do bind with fat - but admitted they were yet to investigate whether the pills actually help people lose weight.

In Professor Regan’s own assessment of Zotrim she stated that Zotrim’s research showed a "clear link to weight loss” with the “difference in weight loss between the group taking Zotrim and the group taking the placebo was significantly different."

Without introducing any changes to their dietary habits or lifestyle, participants were effectively able to reduce their meal sizes, feel fuller faster and experience increases of satiety and energy levels.

Professor Lesley Regan
