FacebookTwitterEmail Chances are, you’ve heard of WW, formerly known as Weight Watchers – I think everyone knows at least one (if not more than one) person who did the program while it was still Weight Watchers. Noom is a newer program that has been growing in popularity recently. If you're not familiar with either, the most obvious difference is the marketing: While WW markets their service with celebrity endorsements from the likes of Oprah and James Corden, Noom prefers to use their own satisfied customers as the face of their brand. If you’re on the fence between the two, I’m here to give you the what’s what on each program and highlight the differences.
