Clinical trials: Sympathetic Disorder
OBESITY, HYPERTENSION
The Autonomic Nervous System and Obesity
In its simplest terms, obesity is the results of a positive balance between food intake and energy expenditure (EE). I.e., we take in more energy, in the form of food, than we expend, e.g., by exercise.
