Eight Principles of Behavior Modification

May 7, 2015

The ongoing and stubborn health epidemic in the United States, combined with healthcare reform and a growing body of behavior change research, has sparked a revolution. It has become clear that “expert advice” does not translate into behavior change for people who are not ready to change. After all, despite doctors’ orders, nearly a third of prescriptions are left unfilled (Tamblyn et al. 2014).

What’s the Best Diet for Me?

February 13, 2015

At any given time, over 100 million Americans are on a diet (MarketResearch .com 2014). That’s about a third of the U.S. population. Despite the hundreds of best- seller diet books and the $60-plus billion Americans spend trying to lose weight each year (Marketdata Enterprises 2014), permanent weight loss remains elusive for most. Even so, dozens of diets remain on the market, each with ardent followers and outspoken opponents.
