It does sound magical: sit on the couch, have another hamburger, swallow a diet pill and watch the pounds melt away!Reading the ads alone for such pills, could cause your self esteem to stumble - "We know you hate the extra pounds, the ugly look and the social stigmata attached to fat people" - I think they meant stigma - even their bad grammar is an important red flag!

Once they break you down, the enticing offers start.

"You don't have to spend the rest of your life exercising yourself to death"

"Thousands of people amazed with immediate results."

"Lose 7 pounds in 7 days" and "#1 Diet Pill in America."

"This is America's fascination with the quick fix. Do I really have to eat less? Do I really have to excercize," asked Tom Bartholomy of the Better Business Bureau.

The Better Business Bureau warns there is no quick fix to weight loss and that consumer complaints are rolling in.

"The top three that we are seeing right now with the most inquiries and most complaints about are things relative to hoodia, ephedra, and anatrim," said Bartholomy.

Hoodia Miracle Diet gets a grade of "unsatisfactory" from the BBB -  and PureHoodia, Inc. gets an "F" - which means the BBB "questions the company's reliability" and that "especially serious allegations" are on file.

"All of them have been on and off the market for a number of years, sometimes banned by the FDA, sometimes re-approved by the FDA," said Bartholomy.

They are easily available on the Internet and in health food stores. Compalints range from lack of results to companies not honoring money back guarantees.

"None of them by themselves will do anything to help you lose weight. There are proven appetite suppressants, but it's not  the magic pill. I mean there are other things that I have to go with it," said Bartholomy.

The best advice is to talk to your doctor about weight loss and adopt a plan that’s safe and effective.
