I wonder if people stop and think how drinking 'slimming tea' or coffee could cause weight loss

Still, perhaps it remains a more convenient false promise than the commitment the guaranteed solution of taking exercise and taking care with your diet would provide.
Googling on 'slimming coffee', just to have a laugh at how it misrepresents it's action, I came upon this below linked. It reminds me of the Chinese powdered milk scandal, where melamine (that's Formica, the plastic veneer used on desk and kitchen worktops), was added as a bulking agent.
Alerts from the US-FDA

'Public Notification: Lishou Slimming Coffee contains hidden drug ingredient
[10-23-2015] The Food and Drug Administration (FDA) is advising consumers not to purchase or use Lishou Slimming Coffee, a product promoted for weight loss. This product was identified by FDA during an examination of international mail shipments.Image of Lishou Slimming Coffee
FDA laboratory analysis confirmed that Lishou Slimming Coffee contains sibutramine. Sibutramine is a controlled substance that was removed from the market in October 2010 for safety reasons. The product poses a threat to consumers because sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke. This product may also interact, in life-threatening ways, with other medications a consumer may be taking.
Health care professionals and patients are encouraged to report adverse events or side effects related to the use of this product to FDA's MedWatch Safety Information and Adverse Event
Note: This notification is to inform the public of a growing trend of dietary supplements or conventional foods with hidden drugs and chemicals. These products are typically promoted for sexual enhancement, weight loss, and body building and are often represented as being “all natural.”

I'm surprised this drug hasn't been banned in Singapore, it sounds potentially dangerous...
