Dr. Mike Roussell knows the nutrition game. On top of being a nutrition expert, Mike is also an author of several books as well as a nutrition adviser for Men’s Health and Shape magazines. He believes in the idea of what he calls the “Psychology of Nutrition” or the mental aspect of eating and dieting. He actually did a research on the eating behaviors of ordinary people, ordinary being people who aren’t really into the whole health and fitness mindset yet. He found out the hardest part of maintaining a diet was not planning or crafting the right nutrition plan rather it was the doing of the nutrition that people find most difficult.
