Ephedra classified as a herb and use for weight loss increases. 1995 Dexfenfluramine (Redux) was developed as an alternative to fenfluramine with less side-effects. 1990’s 1997 Removal of fen-phen is called for by the FDA after reports linking fen-phen with heart valve problems. Redux removed from the market due to similar problems relating to cardiovascular health. 1998 Meridia is put on the market. 2000’s 2004: Ephedra removed from the US market from concerns with raising blood pressure which could lead to strokes and death. 2009 Hydroxycut diet supplements pulled off the market after reports of liver damage.

In 2005, TrimSpa was sued for Anna's erratic behavior at a concert- associated with slurred speech and behavior http://www.youtube.com/watch?v=A4GsS5ua4MEh t TrimSpa Baby! Potential TrimSpa Side Effects and Concerns Original TrimSpa formula contained the stimulant herb ephedra Expensive (>$48/month) No longer individually lists the ingredients Side effects may include anxiety and insomnia (rec. amount of 4 pills/day = two 8-ounce coffee) May trigger migraines (tyramine) Shouldn’t be taken with Monoamine Oxidase Inhibitor(MAOI) antidepressant drugs What’s good about TrimSpa? Contains glucomannan, a water-soluble dietary fiber derived from konjac root Keeping Up With the Kardashians “How HOT Can You Be?” Kim claims to have lost 15 lbs, Khloe 25 lbs(some of which she gained back) Advertises “to help burn calories, support energy levels, and supercharge workouts” (getquicktrim.com) Pressures women receive: Temptation of getting that bikini body Kim and Khloe Kardashian use sex to sell their QuickTrim diet pills http://www.youtube.com/watch?v=Q69Igo7xcGA 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 QuickTrim 4 QuickTrim products Sculpting gel for cellulite 14-day "burn and cleanse“ 48-hour cleanse 8-hour weight loss formula that burns calories 300% x faster All of which are advertising fast weight loss.

At best, these diet pills will produce short-term weight loss because they stimulate or speed up metabolism and act as diuretics Since 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 Problems with Diet Drugs 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, osteoporosis FTC challenges marketing of claims -> required to back up claims with the science Fines levied against 4 over-the-counter non-prescription diet pills: Xenadrine, One a Day Weight Smart, CortiSlim, TrimSpa A combined $25 million Receive money back when consumers have been deceived Ex: Bayer Corp. paid $3.2 million civil penalty to settle claims and agreed to stop ads that say “multivitamins can increase metabolism” Trying to lose weight? Don’t turn to pills! FTC claims there are NO scientific evidence that diet pills cause weight loss Testimonials from individuals are not a substitute for science FTC 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! Counterfeit Diet Pills Booming trade in counterfeit slimming pills Medicines and Healthcare Regulatory Agency(MHRA) sited 2 prescription-only anti-obesity pills: Xenical, Reductil Very commonly counterfeited in UK Through illegal pharmacies and illegal websites where demand is high and maximum profits are made Fake prescription obesity pills contain little active ingredient, some may cause harm Made in substandard conditions, contain impurities No true regulation (no prescription necessary) Problems There is NO medical or other supervision of any kind May be easily abused. Ex: In fact, teenage girls are some of the heaviest users of retail diet pills, because they’re easily accessible.
