25 QuickTrim“This product isn’t intended to be a complete replacement for having a reasonably healthy diet and lifestyle” (kardashiansquicktrim.com)Dangers of Kardashian-Endorsed QuickTrim4 QuickTrim productsSculpting gel for cellulite14-day "burn and cleanse“48-hour cleanse8-hour weight loss formula that burns calories 300% x fasterAll of which are advertising fast weight loss.

27 Lose it on the QT!Fast Cleanse- “48-hour Super Diet Detox” to drop a dress sizeFiber-rich drink 4x/day b/w mealsPrimarily a digestion-resistant polysaccharidesExtreme Burn- supposed to be used long term after finishing 14-day planContains a lot of caffeine and herbs to boost potencyPowerful stimulants, laxatives, and diuretics.At best, these diet pills will produce short-term weight loss because they stimulate or speed up metabolism and act as diureticsSince under "supplements" instead of “medications”, they are NOT required to undergo rigorous FDA testing to ensure they are safe and do what their manufacturers claim they do
29 Diet Pill Makers Misleading Consumers Federal Trade Commission says some diet companies make false advertising claims ranging from rapid weight loss to reducing risk of cancer, Alzheimer’s, osteoporosisFTC challenges marketing of claims -> required to back up claims with the scienceFines levied against 4 over-the-counter non-prescription diet pills:Xenadrine, One a Day Weight Smart, CortiSlim, TrimSpaA combined $25 millionReceive money back when consumers have been deceivedEx: Bayer Corp. paid $3.2 million civil penalty to settle claims and agreed to stop ads that say “multivitamins can increase metabolism”
30 Trying to lose weight? Don’t turn to pills! FTC claims there are NO scientific evidence that diet pills cause weight lossTestimonials from individuals are not a substitute for scienceFTC also said that customers using the products and providing testimonials were paid as much as $20,000 for their “endorsements.”The media and women’s magazine have been “urged” to refuse or remove these type of ads from their magazines, or investigate the claims being made.But doesn’t because they want the revenues!
31 Counterfeit Diet Pills Booming trade in counterfeit slimming pillsMedicines and Healthcare Regulatory Agency(MHRA) sited 2 prescription-only anti-obesity pills: Xenical, ReductilVery commonly counterfeited in UKThrough illegal pharmacies and illegal websites where demand is high and maximum profits are madeFake prescription obesity pills contain little active ingredient, some may cause harmMade in substandard conditions, contain impuritiesNo true regulation (no prescription necessary)
