Whey Protein Suppresses Hunger?

vidence suggests that high protein diets are beneficial for weight loss. A number of intervention studies have assessed different types of high protein diets and generally the result show that they cause weight loss when compared to high carbohydrate alternatives. … Continue reading

Sleep Stress: Obesity Trigger?

Stress causes adaptation and allows beneficial changes to occur in organisms. For example, exercise is a form of stress that forces physiological adaptations to improve physical performance. However, following application of a stressor, time must be allowed for adaptation. During … Continue reading

Is the Brain a Digestive Organ?

The perceived energy content of foods is predictive of the self-reported appetite sensations elicited thereafter. Further, sensory experience, which may include the visual appeal of packaging, the aroma, or the associations drawn through advertising and branding, are known to affect … Continue reading

More on Resistance Starch

Resistant starch, also known as dietary fibre, represents the fraction of carbohydrate intake that contains glycosidic bond types that result in incomplete hydrolysis by human digestive enzymes. Such carbohydrate was once considered to be important to health solely because it … Continue reading

Chewing and Energy Intake

Traditionally, obesity has been thought of as a simple energy imbalance, whereby calorie intake becomes too great when compared to the amount of energy expended on metabolic processes and physical activity. However, within the last decade, a picture is emerging … Continue reading

Breakfast Affects Subsequent Feeding Habits

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

Playing Electronic Games Increases Energy Intake

Research has shown that playing electronic games and watching television can cause weight gain and are associated with obesity. For example, subjects playing an electronic game while eating have been shown to consume more energy when compared to those given … Continue reading

Lack of Sleep Causes Increased Energy Intake

The purpose of sleep is not fully understood, but it is thought to be an important period of restoration that is aided by hormonal changes. Research shows that adults who attain less than 7 hours of sleep a night have … Continue reading

Peptides that Regulate Feeding Behaviour: The Orectic Peptides

As discussed previously (here), there are a number of peptides that have been identified within mammals that regulate feeding behaviour. Anorectic peptides that act to reduce food intake include insulin, leptin, somatostatin, bombesin, calcitonin, cholecystokinin, corticotrophin releasing factor and peptide … Continue reading

Viscosity of Drinks and Gut Hormones

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
