The Homeostasis of Weight Control

Posted on July 26, 2016 by Robert Barrington

The traditional model of body weight loss considers the only two factors relevant to weight loss to be energy consumed and exercise performed. In this model, energy balance is an equilibrium between these factors. Part of this assumption considers energy … Continue reading →

Fibre and Protein: Weight Loss Foods

Posted on September 23, 2015 by Robert Barrington

Protein is a weight loss food. Evidence from the nutritional literature suggests that eating a high protein diet causes weight loss in those who are overweight. The reason for this in not clear, but the weight loss effects of protein … Continue reading →

Protein: Gut Hormones and Satiety

Posted on May 9, 2014 by Robert Barrington

High protein diets show weight loss effect when compared to high fat or high carbohydrate diets. The reason for this is unknown, but protein has satiety inducing effects and this may contribute to its anti-obesogenic effects. The mechanisms by which … Continue reading →

Breakfast Affects Subsequent Feeding Habits

Posted on September 3, 2012 by Robert Barrington

Reports suggest that decreasing numbers of people are consuming breakfast regularly, and yet at the same time evidence suggests that breakfast may be protective of obesity. For example, epidemiological studies have reported that regular consumption of breakfast is associated with … Continue reading →

Peptides that Regulate Feeding Behaviour: The anorectic Peptides

Posted on June 5, 2012 by Robert Barrington

Peptides that regulate appetite have been identified in the tissues of the gastrointestinal tract, pituitary, pancreas, hypothalamus and general neural tissues of mammals. These peptides tend to show paracrine, autocrine and endocrine functions that synergistically allows the regulation of energy … Continue reading →

Nutrient Detection Regulates Energy Balance

Posted on May 18, 2012 by Robert Barrington

Mammals can maintain energy balance despite large fluctuations in physical activity and energy intakes because they have complex neuronal and hormonal systems that regulate appetite, satiety and metabolism. Short term appetite regulation is achieved by receptor mediated detection of food … Continue reading →

Peptide YY

Posted on May 17, 2012 by Robert Barrington

Peptide YY is a gut hormone consisting of 36 amino acids which shares structural similarity to neuropeptide Y and pancreatic polypeptide. Peptide YY is released from the mucosa of the ileum of the small intestine and the colon where it … Continue reading →

Viscosity of Drinks and Gut Hormones

Posted on January 6, 2012 by Robert Barrington

A number of gut peptides are known to be involved in inducing a feeling of satiety and reducing further food intake. Many of theses act locally on the gastrointestinal tract, but others enter circulation and act on the central nervous … Continue reading →

The Regulation of Energy Balance

Posted on January 5, 2012 by Robert Barrington

Despite daily fluctuations in energy intake, energy balance is maintained in humans such that body weight can remain constant for long periods of time. The maintenance of a constant body weight occurs because the body has a sensitive homeostatic feedback … Continue reading →
