1 / 6 6) McLean Deluxe

In 1991, McDonald’s tried to go the healthy route, crafting a buger dubbed the McLean Deluxe that would stand up to its critics, showing them the fast-food giant could offer low-fat options on a menu laden with trans fat and high-calorie products. The advertising campaign boasted a new kind of burger that was 91 percent fat-free with 10 grams of fat, compared to the Big Mac's 26 grams of fat. The burger actually contained seaweed that was meant to bind the meat together as a way of lowering the fat content. Needless to say, the burger was not a hit with customers and critics dubbed it the "McFlopper." <a href="http://www.thedailymeal.com/mcdonalds-10-most-spectacular-menu-flops?utm_source=huffington%2Bpost&utm_medium=partner&utm_campaign=mcdsflops" target="_hplink"><strong>Click here to see All of McDonald's Menu Flops</strong></a> <a href="http://www.flickr.com/photos/jbcurio/" target="_hplink"><em>Credit: flickr/ jbcurio</em></a>
