During the past 30 yr, investigating the physiology of eating behaviors has generated a truly
vast literature. This is fueled in part by a dramatic increase in obesity and its comorbidities …

Despite the large volume and extensive range of obesity research, there is substantial
disagreement on the causes and effective preventative strategies. We suggest the field will …

Objective Dietary protein restriction induces adaptive changes in food preference,
increasing protein consumption over carbohydrates or fat. We investigated whether …

Feeding behavior is guided by multiple competing physiological needs, as animals must
sense their internal nutritional state and then identify and consume foods that meet …

The study of consummatory responses during food intake represents a unique opportunity to
investigate the physiological, psychological and neurobiological processes that control …

A growing literature suggests manipulating dietary protein status decreases sweet
consumption in rodents and in humans. Underlying neurocircuit mechanisms have not yet …

Pharmacological administration of fibroblast growth factor 21 (FGF21) alters food choice,
including that it decreases the consumption of sucrose and other sweet tastants. Conversely …

Free-feeding animals navigate complex nutritional landscapes in which food availability,
cost, and nutritional value can vary markedly. Animals have thus developed neural …

Low-protein diets can impact food intake and appetite, but it is not known if motivation for
food is changed. In the present study, we used an operant behavioral task–the progressive …

Disordered eating can underpin a number of debilitating and prevalent chronic diseases,
such as obesity. Broader advances in psychopharmacology and biology have motivated …
