We give competitive golfers a simple, proven nutrition system designed to increase energy, sharpen focus, and improve consistency from the first tee to the final putt. Built by PGA Tour winner Derek Ernst, this program makes pro-level fueling easy for anyone.
About Derek Ernst
For most of my life, I believed better golf came from better swings.
After competing at every level of the game—from junior golf in California, to playing on the PGA Tour, and now coaching one of the nation’s top collegiate golf programs—I realized something many golfers overlook:
The best players don’t just train differently. They fuel differently.
Throughout my playing career, I experienced firsthand how nutrition affected my energy, focus, recovery, body composition, and performance. Some weeks I prepared well. Other weeks I didn’t. The difference wasn’t just how I felt—it showed up on the golf course.
That realization sparked a passion to study performance nutrition and learn how elite athletes can maximize their potential through better daily habits.
So, I created DEEP Golf Nutrition to simplify that process. My mission is to help golfers stop guessing about nutrition and start building habits that improve performance both on and off the course.
