In animals, including humans, free access to high-quality (generally energy-dense) food can
result in obesity, leading to physiological and health problems. Consequently, various …

The compulsive nature of weight loss behaviors central to anorexia nervosa (AN), such as
relentless self-starvation and over-exercise, has led to the suggestion of parallels between …

1. The science of nutritional ecology spans a wide range of fields, including ecology,
nutrition, behaviour, morphology, physiology, life history and evolutionary biology. But does …

There is growing evidence that, rather than maximizing energy intake subject to constraints,
many animals attempt to regulate intake of multiple nutrients independently. In the complex …

Many factors contribute to how much we eat. One such factor is the variety of different foods
available. The current article reviews the variety literature with a specific focus on the factors …

Optimal time allocation to foraging behaviour may be constrained by intrinsic and extrinsic
factors forcing animals to adopt compromises to meet their daily energetic needs. Our goal …

This study aimed to verify the effects of heat stress and dietary energy level on dry matter
intake (DMI), water intake, total and partial ruminal and intestinal digestibilities, ruminal …

Restricted food intake is associated with increased physical activity, very likely an
evolutionary advantage, initially both functional and rewarding. The hyperactivity of patients …

The nutrition transition has created an obesogenic environment resulting in a growing
obesity pandemic. An optimal foraging approach provides cost/benefit models of cognitive …

The question of how much time a foraging herbivore should spend in a patch of food poses
a central challenge in classical foraging theory. However, there remains uncertainty about …
