All animals face the possibility of limitations in food resources that could ultimately lead to
starvation-induced mortality. The primary goal of this review is to characterize the various …

▪ Abstract The ability of animals to survive food deprivation is clearly of considerable survival
value. Unsurprisingly, therefore, all animals exhibit adaptive biochemical and physiological …

In recent years a revival of interest has emerged in the health benefits of intermittent fasting
and long-term fasting, as well as of other related nutritional strategies. In addition to meal …

Patients with anorexia nervosa (AN) often show normal to elevated physical activity levels
despite severe weight loss and emaciation. This is seemingly in contrast to the loss of …

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 …

Mammals and birds adapt to prolonged fasting by mobilizing fat stores and minimizing
protein loss. This strategy ends with an increase in protein utilization associated with …

The physiological challenges initiated by food limitation and the risk of death by starvation
were likely faced by the very first animals and show no signs of abatement within the …

Phocid seals are one of the few groups of mammals capable of sustaining the energetic
demands of lactation entirely through body nutrient stores while fasting. Lactation …

During long-term fasting at rest, protein utilization is maintained at low levels until it
increases at a threshold adiposity. This study examines 1) whether such a shift in energy …

Background Our evolutionary history is defined, in part, by our ability to survive times of
nutrient scarcity. The outcomes of the metabolic and behavioural adaptations during …
