When is a diet pill worth $150?

Never...

In a standard high pressure sale, miss "never been more than 10 pounds overweight" tells you that this pill is not for you if you're just trying to lose a few vanity pounds. That guarantees that they will be the biggest buyers.

What's in this wonder pill: caffeine, ephedrine, green tea extract, l-tyrosine, cayenne, and various vitamins and minerals. This is known as an "ECA Stack" and the makers of this wonder pill claim that their propriety mixture makes their pill far more effective than other pills with same ingredients.

They also claim: " First , significantly overweight people have a genetically-based tendency to store excess dietary calories as body fat. [ the pill ] helps overcome this tendency by effectively increasing the body's ability to destroy calories in specialized "wasting cycles" within fat, muscle, liver and other body cells.
Second , [ the pill ] dramatically interferes with the process of converting calories to fat.
Third , [ the pill ] exerts a profound "lipolytic" action ? it "mobilizes" stored fat, moving it out of the fat cell and thereby reducing the size of the fat cell mass.
Fourth , [ the pill ] inhibits the creation of new fat cells (yes, scientists now know that we create new fat cells throughout life).
Fifth , [ the pill ] increases the special process (called apoptosis) in the body that results in the destruction of immature fat cells before they become bloated with fat.
Sixth , [ the pill ] is especially effective in prolonging all of these actions in the body for the longest possible time. "

Just looking at the first five claims, this pill should not be over the counter if they were true. Number six is just a variation of "tiny time pills", a buffering coating that burns off slowly.

How does this pill work? Look at the first two ingredients: Caffeine and Ephedrine, both stimulants. I'd be thin as a rail if caffeine worked for me and Ephedrine is contra-advised by by the FDA:

It can kill, it is also used in the manufacture of the street drug Ecstasy! Ephedrine is an amphetamine-like chemical derived from plants. It can cause heart attacks and other metabolic problems.

Is this pill worth your life? No, not ever.
