An automated accessibility tool is a piece of software which can test a web page, or even an entire website, for accessibility. Automated accessibility tools are useful because they can save you a huge amount of time. Don't want to check images for alt text on each and every page on your website? Run the site through an automated tester and it'll do it all for you!

Automated accessibility testing tools have been around for a long time and have historically been a useful way of checking websites for accessibility. Bobby, one of the first and most well-known automated accessibility testing tools, is now almost 10 years, and although is no longer freely available, plenty of other free tools such as WebXact () and Wave ()do exist.

But are these tools a little too good to be true? Can you test a website for accessibility so easily? Unfortunately the answer is a resounding no. There are a number of underlying problems associated with using just automated tools to test for accessibility:

Do they work? Yes -- you do lose weight initially on a High Protein/Low Carb diet but 90% of your initial weight loss is water. And that's where the problems begin.

What happens after your body has shed its water weight? It starts to burn the left over fat and then, because it lacks carbohydrates to burn for energy, it starts to burn protein - your muscles. These diets induce a metabolic condition known as ketosis which is really an unhealthy condition found in people who suffer from kidney disease and diabetes. It is not usually found in healthy people. Burning protein is not healthy because protein is nature's building material and is vital for repairing and rebuilding your body's cells, tissues and organs. Advocates of the Low Carb/High Protein/Fat diets play down ketosis and claim it's proof your body's burning fat. That's true in part. Ketosis does burn fat but will also, eventually, burn your body's muscle tissue.
