The Core Diet

You won't believe how good you'll feel

The Core Diet for Athletes was developed 12 years ago by QT2 Systems coach and founder Jesse Kropelnicki. The Core Diet was designed to help athletes live, train, and compete at their optimal level.

Through proper nutrition that includes nutrient rich foods consumed at the right time, the Core Diet will have you performing and living at your very best. You really won't believe how good you feel!

At the Core Diet we believe it is not just important to know what to eat, but to know why you are eating it. We teach the logic behind sports nutrition to make it sustainable for a lifetime...The Core Diet is not a fad, but a lifestyle.  As Jesse says, you are always better off being 80% compliant for 10 years, than 100% compliant for 8 weeks. 

Whether it be to maintain an already healthy weight, lose weight, or fuel training and racing, the Core Diet can provide you with a plan that suits your individual needs.

Approved Foods

The Core Diet is focused around those foods which are the the most nutrient dense, and critical for athletes to focus on to improve performance, improve health, and reach, or maintain body composition. The Core foods, lean meats, fruits, veggies, nuts, seeds, lean dairy, and legumes, are the backbone to the program. Other less nutrient dense foods serve a specific purpose and are timed to provide athletes a benefit to their training, and decrease the storage of unwanted body fat.
