body weight is influenced by both food intake and energy expenditure. acylated ghrelin enhances appetite, and its circulating level is suppressed by growth hormone. data on the acylated ghrelin responses to exercise of different intensities in obese individuals are currently not available. this study examined the effects of an intermittent exercise protocol on acylated ghrelin levels and hunger...

Rats acquired a preference for an aqueous odor (almond) presented in simultaneous compound with sucrose. Separate presentations of saccharin reduced this preference in rats with ad-lib access to food during training or at test, but not in rats that were hungry during both training and test. In contrast, separate presentations of sucrose reduced the preference for the almond irrespective of depr...

Sustainable development and poverty alleviation are two intertwined issues that continue to be accorded the highest priority by decisionmakers. This paper seeks to anlayse the nexus between these two topics within a transdisciplinary integrative framework (sustainomics). Following the 1992 Earth Summit in Rio de Janeiro, including the adoption of the United Nations’ Agenda 21, and the 2002 Worl...

One of the World's greatest challenges is to secure sufficient and healthy food for all, and to do so in an environmentally sustainable manner. This review explores the interrelationships of food, health, and environment, and their role in addressing chronic micronutrient deficiencies, also known as "hidden hunger", affecting over two billion people worldwide. While the complexity and underlyin...

A central goal of neuroscience is to understand how neural dynamics bring about the dynamics of behavior. However, neural and behavioral measures are noisy, requiring averaging over trials and subjects. Unfortunately, averaging can obscure the very dynamics that we are interested in, masking abrupt changes and artificially creating gradual processes. We develop a hidden semi-Markov model for pr...

A healthy meal is a complex cocktail of macroand micro-nutrients. Yet, when it comes to discussing diets, we typically consider calories to be the central drivers of hunger and obesity, disregarding other factors. The threat that climate change poses to agricultural productivity and food security around the world, especially in the tropics and sub-tropics, is also usually analysed only in terms...
