In 2008, after losing his son and father within a year, Brian found himself tipping the scales at well over 300 pounds.  He knew his life had to change.  He immersed himself into furthering his education, receiving his degree in Holistic Nutrition with an emphasis on Biochemistry and Physiology from the Global College of Natural Medicine (now the University of Natural Health at Kingdom University).  Brian lost over 150 pounds, transforming his body and his life.

In 2010 Brian began his nutritional practice through a chiropractor’s office and then branched out on his own in 2012, starting Nessel’s Nutrition.  Since 2010, Brian has counseled over 12,000 patients from around the world.  He receives referrals from over 100 doctors throughout the Midwest and has been published numerous times in Health and Fitness magazines and media.  By 2018, Brian had helped his patients lose over 120,000 pounds, get off thousands of medications, and find a new path to life-long health and fitness.

In 2023, Brian opened his own training gym to pursue his passion for fitness and weight training. The gym has certified personal trainers that run weightlifting circuit classes to help their clients gain strength, work on their metabolism, and gain an overall sense of well-being.
