You may be surprised to know that I, a medical doctor, do believe that there are certain pills that help with weight loss. I am certain of this. Even though the medical establishment is skeptical, if doctors learned more about these natural weight loss pills and actually used them in their practice, they would soon find out that they are effective. There are two ways to lose weight -- either reduce energy intake, or increase energy use.

Does the medical establishment or does the mainstream media understand the benefit of natural herbs?
A number of weight-loss pills are available online or at your local health food store, drugstore, or supermarket
. Most mainstream articles in magazines and newspapers question the effectiveness of these weight loss pills.

Here, you will get an honest review of the benefits and shortcomings of these natural weight loss pills and you will find our which of them work, and which have little or no basis to support the claims made by advertisers.

Przegl Lek. 2013. Acute poisoning with weight-loss dietary supplement falsely suggesting the use of amphetamine, We report a case of abuse of weight-loss dietary supplement in 27-year-old man, with characteristic for amphetamine sympathomimetic symptoms and positive analysis of this drug in the urine by immunoassay method (FPIA; Axsym, Abbott). However positive result was not confirmed by liquid chromatography coupled with tandem mass spectrometry (LC-MS-MS). The patient ate nine tablets of the Thermal Pro with declared composition of caffeine (250 mg), bitter orange (200 mg), beta-phenylethylamine (100 mg), willow bark (75 mg), Cayenne pepper (40 mg), 1,3-dimethyloamyloamine (DMAA, 35 mg), gooseberry extract (20 mg), bergamot orange (20 mg), black pepper (5 mg), after two-month period of regular consumption at dose of 2-3 capsules per day. After 4 hours, during admission to the Department of Toxicology, patient manifested typical sympathomimetic symptoms: anxiety, agitation, pale skin, sweats, tachycardia 120/min, mydriasis. Following the outcome of detecting amphetamine / methamphetamine in the patient's urine at 2377 ng/mL concentration, drug intoxication was suspected. It was considered that the ingestion was intentional or unconscious of adulterated dietary supplement. In view of the strong opposition of the patient, who denied any use of psychoactive substances, it was decided to re-examine collected speciments. The liquid chromatography coupled to tandem mass spectrometry (LC-MS-MS) method did not confirm the presence of amphetamine in the patient's blood and urine. Based on the composition of dietary supplements for substances which could be responsible for the positive amphetamine result in urine by FPIA method and available literature data, it was concluded that the substances that may react in the immunoassay could be dimethylamyloamine (DMAA, geranamine) or bitter orange components. False positive urinalysis towards amphetamine/methamphetamine by immunoassay and presence of sympathomimetic effects may contribute to a false diagnosis of this drug poisoning. Definitive confirmation of such intoxication requires the use of the reference methods.
