Dr. Derek (Owner)
Derek Alessi, PhD (Dr. Derek™) became interested in the field of fitness training at an early age when he was an obese teenager. Determined to change his health, body and ultimately his future, he began strength training and developed a system to modify his nutrition. Derek dropped over 80-pounds in one year and later that same year, he entered his first and only body building contest. Disenchanted with the way body building tends to minimize health and well-being in order to encourage raw size, he left that arena and dedicated his career to helping individuals achieve better health and wellness through a program of planned exercise and practical nutrition. At the age of 19, Derek passed a national fitness certification exam and began his career in personal fitness training. He furthered his quest for more information through education and received post-graduate degrees in health and physical education as well as a master’s degree in nutrition.
As America’s Premier Health Advocate Dr. Derek’s core belief is that health and fitness are not a result of gimmicks, hype or the latest butt buster. Instead they are achieved by understanding the physiological complexities of the body and the synergistic role that the right kinds of exercise along with supportive nutrition can play in unlocking the healthy body that is inside every one of us.
Dr. Derek is passionate about body fat reduction, medication reduction and help individuals improve the quality of their lives. His practices incorporates: glucose, ketone, body fat and deep sleep tracking along with the right kind of diet and intelligent exercise to extend life and improve lifestyle.
