Meet the Team

Dr. David Plourdé

Dr. David Plourdé holds a Ph.D. (Doctor of Philosophy) with a concentration in interdisciplinary sciences: with specializations in the fields of human nutrition and exercise physiology from Union Institute & University in Cincinnati, Ohio. Prior to receiving his doctoral science credentials, he was a social worker with a background in food addiction recovery, graduating with a bachelor of arts in social work from the University of Wisconsin-Whitewater.

As a devout follower of Jesus Christ, his original intention was to go to seminary after completing his undergraduate degree, however, that all changed after having had a spiritual awakening about the new calling and direction for his life in science.

Dr. Plourdé has been practicing in a laboratory setting studying human nutrition, chemistry, metabolic research, exercise physiology, muscle metabolism, body composition science, the psychology of eating behavior, and food addiction recovery for 31 years (over 84,000 clinical hours).

Thousands of overweight men and women (from California to New York - from Minnesota to south Florida) have successfully lost clinically significant amounts of body fat weight through his scientific weight loss method.

With the help of a team of brilliant field experts - Dr. Plourdé relentlessly pursued three primary objectives in his formal research:

  1. To develop a non-invasive technique to monitor the enzyme mechanism, Hormone Sensitive Lipase (HSL), that regulates the weight of each individual fat cell.
  2. To develop an interdisciplinary scientific method (which eventually became The Plourdé Method ® ) to control the HSL enzyme, and thus reduce fat cell weight and body fat levels in a totally predictable fashion.
  3. To select & establish a statistical tool that would predict when body fat weight loss would biologically plateau in an overweight person - (guided by objective scientific principles) similar to how the yellow light comes on in the dashboard of your vehicle indicating you’ve gone critically low in fuel levels.

Dr. Plourdé was able to accomplish these objectives through the implementation of three human trials, tracking over 308 subjects divided among those three trials over a 15 year period with seven day a week doctor-patient interaction.

The ensuing Plourdé Method® has become the exact road map to successfully navigate your own weight loss journey while benefiting from decades of clinical experience by the nation’s leader in science based weight loss.

Dr. Plourdé is now entering into a new chapter of his career, becoming an author and speaker. His first book will be published within the next year.
