In a recent research report, [Bodenlos et al. 2007. Vagus nerve stimulation (VNS) acutely alters food craving in adults with depression. Appetite, 48, 145–153] concluded that, in depressed patients, acute activation of a device for VNS caused a significant change in cravings specifically for sweet foods. We argue that there is no evidence for any effect on food cravings. Rather, the findings indicate...
In their defence of their original paper, Bodenlos, Borckardt and George (2007) maintain that there is little consensus in measurement of food craving and their own measure bears some resemblance to others. However, we argue that a useful concept of craving, and its measurement, must be distinguished from more general measures of appetite. Furthermore, we believe that their defence of their own significant...
Despite the overwhelming evidence linking alcohol to the development of disease, the contribution of alcohol toxicity to ill health remains controversial. One of the major problems facing researchers is the fact that alcoholic beverages, which contribute little to the nutritional requirements of the body, are often substituted for food and nutritional deficiency alone can promote cell damage. Long-term...
The leaves of the khat plant (Catha edulis) are chewed for their pleasurable effects. Chewing releases cathinone which may decrease appetite through an unknown mechanism. Levels of the peptide ghrelin increase with hunger and decrease immediately post-prandially, while peptide YY is released following a meal. We hypothesised that the anorexigenic effects of khat may be mediated through changes in...
Long chain omega-3 fatty acids (LC n-3 FA) are considered nutritional factors with a potential to modulate food intake. Thus, the aim of the current study was to determine whether appetite could be affected by LC n-3 FA when included in a calorie-restricted diet to treat overweight or obesity.Appetite was explored in volunteers (31±5 years; BMI: 28.3±1.5kg/m 2 ) during the last 2 weeks of...
Twelve 11-year-old girls (six lean, six overweight) were given meals in the laboratory and at school for 5 days, with exercise imposed for 2 days and sedentary activities on another 2 days in counterbalanced sequences. During a preliminary visit, the FLEX heart rate method was used to predict individual exercise durations eliciting 1.5MJ energy expenditure. Morning and afternoon cycling exercise was...
Sodium alginate is a seaweed-derived fibre that has previously been shown to moderate appetite in models of acute feeding. The mechanisms underlying this effect may include slowed gastric clearance and attenuated uptake from the small intestine. In order to assess whether alginate could be effective as a means of appetite control in free-living adults, 68 males and females (BMI range: 18.50–32.81kg/m...
