The present study tested the hypothesis that habitual exercisers demonstrate an increased accuracy of regulation of food intake in compensation for previous dietary energy intake. Twenty-three lean healthy male subjects were divided into two groups on the basis of their habitual exercise levels: non-exercisers (no exercise sessions/week, n 9), and exercisers (>two exercise sessions of 40 min or...

This article investigates the reasons behind the disappearance of Francis Glisson's theory of irritability during the eighteenth century. At a time when natural investigations were becoming increasingly polarized between mind and matter in the attempt to save both man's consciousness and the inert nature of the res extensa, Glisson's notion of a natural perception embedded in matter did not sat...

Some particles are heavier than others, say a trio of theorists, because they are first in line to fill their plate at the source of mass Why are some things heavier than others? In the case of people, the answer clearly has a lot to do with what gets plunked down on the dinner table. For fundamental particles, however, the answer has never been obvious. In fact, it's so mysterious that the bri...

To optimize fitness, animals must dynamically match food choices to their current needs. For drosophilids, yeast fulfills most dietary protein and micronutrient requirements. While several yeast metabolites activate known gustatory receptor neurons (GRNs) in Drosophila melanogaster, the chemosensory channels mediating yeast feeding remain unknown. Here we identify a class of proboscis GRNs requ...

In addition to usual division of the subject and the usual description of the various humoral systems, three chapters deal specially with three items : (1) Neuroendocrine and Psychosomatic Aspects of the Endocrinopathies. 'The psychologic forms which contribute to the development and integration of the personality structure stem not only from the biologic inheritance of the human race but also ...

Obesity and overeating have become fundamental problems in modern society. This article studies the inhibition of food-seeking behavior, and how contextual cues can control it. Rats that had free food in the home cage nevertheless learned to lever press for sucrose or high-fat pellets in a distinctive context (a Skinner box). Lever pressing was then inhibited by extinction, in which lever press...

While it has been proposed, based on epidemiological studies, that whole grains may be beneficial in weight regulation, possibly due to effects on satiety, there is limited direct interventional evidence confirming this. The present cross-over study aimed to investigate the shortterm effects on appetite and food intake of 48 g of whole-grain wheat (daily for 3 weeks) compared with refined grain...

A paragraph on the negative side of Romanticism, however, is in order, since Romanticism is negative at base: it developed in understandable disillusionment over the excessively optimistic claims of the Enlightenment after the fiasco of the French Revolution and its aftermath. Its discontent was wider than the Enlightenment, however: it was a discontent with civilization as such, as was argued ...

The commercial laying hen has demonstrated appetites for energy, protein and calcium. Compounded layer diets are balanced with respect to energy as it is generally considered that the energy appetite of the bird is dominant. The current practice of feeding compounded diets has been shown to be inefficient where environmental or disease status alters the bird’s energy metabolism (Mastika, 1987; ...

OBJECTIVE To investigate the influences of resources and food-related goals on the variety of food choice among older people. DESIGN A questionnaire-based survey in eight European countries: Poland, Portugal, United Kingdom, Germany, Sweden, Denmark, Italy and Spain. SUBJECTS Participants (n 3200) were above 65 years of age and living in their own homes. The samples were quota samples, eigh...
