Dr. Bissonnette brings a credible and unique perspective to the discourse on obesity, working as a dietitian for several years in an outpatient clinic that treated obesity and morbid obesity. Later, he received his doctoral degree in the nutritional sciences with a focus on biochemistry and epidemiology from the faculty of medicine at the University of Toronto. Consequently, he has a solid medical and epidemiological background on the understanding of population health and the biochemical and metabolic implications tagged to obesity, caloric restrictions, and weight regain. Dr. Bissonnette also understands, first hand, the frustration experienced by physicians, NPs, PAs, and dietitians, as they attempt to manage the majority of obese and overweight patients who fail to lose sufficient weight while following restrictive caloric diets.
