If you watch cable TV or listen to talk radio, you can't escape the ads for CortiSlim, which make the irresistible pitch that it's not your fault that you're fat. The problem, you see, is that you're stressed out. Their pills are supposed to fix that.

A nationwide consumer class action lawsuit against the manufacturer and distributor of CortiSlim charges that the company's claims are false and misleading.

The CortiSlim pitch goes something like this: when you're under stress, your body releases a hormone called cortisol, which does a lot of things, including increase your appetite. Not only that, we're told that cortisol actually influences where the fat from all that stress-related eating goes - straight to your belly.

The ads for CortiSlim say it blocks cortisol, which helps you lose weight without a lot of diet and exercise.

The suit charges CortiSlim with using a series of misleading infomercials in which the human body's ability to regulate weight loss is allegedly linked to the body's production of a chemical substance called cortisol. Contrary to the company's advertisements, the suit charges the defendants' marketing claims are unsubstantiated and lack a valid scientific basis.

The official CortiSlim Website features a FAQ section that is somewhat vague about when consumers of the product will see results. However, it advises users to not weigh themselves for the first 30 days of using the product. In fact, the company recommends not using a scale to measure the product's effectiveness!

The lawsuit seeks a refund for all consumers who relied on the company's claims.
