Thermogenic Synergy

Posted on September 26, 2024 by Robert Barrington

A range of thermogenic agents have been investigated for their effects in humans. Of the agents tested, a large number of effective thermogenic agents from plants have been identified. However, often the size of the effects is small and should … Continue reading →

Thermoregulation: The Key to Weight Loss

Posted on November 11, 2022 by Robert Barrington

Many “experts” claim that calories in minus calories out equals net weight gain. Based on this it is often claimed that by adding up all energy in food, subtracting the basal metabolic rate and the energy used in exercise, a … Continue reading →

The Importance of Taking Breakfast

Posted on October 18, 2016 by Robert Barrington

Breakfast is literally named because it breaks the overnight fast. In this regard, it has very important metabolic implications. During the night, as fasting proceeds, an increasing catabolic state is entered whereby stored tissues are catabolised and then oxidised to … Continue reading →

More on Dietary Thermogenesis

Posted on July 4, 2016 by Robert Barrington

The thermic effect of food and the thermic effect of exercise are often overlooked when energy balance is considered. Obesity is considered by many to be a simple balance between energy consumed and energy expended, but this does not take … Continue reading →

Calorie Counting: More Holes

Posted on July 31, 2015 by Robert Barrington

Calorie counting relies on the energy balance equation to explain body weight changes. Proponents of calorie counting claim that the change in body weight experienced by an individual is related solely to the amount of physical activity they perform, in … Continue reading →

Resting Metabolic Rate Increases With Body Weight

Posted on December 30, 2014 by Robert Barrington

The resting metabolic rate (RMR) is the energy expended by the body at rest with the individual sitting or lying. In other words it is the energy required for normal metabolic and homeostatic regulation. The basal metabolic rate is similar … Continue reading →

Smoking and Body Weight

Posted on December 18, 2014 by Robert Barrington

Both smoking and obesity increase the risk of mortality. However, smoking is inversely related to body weight. This suggests that something about the act of smoking, or its associated behaviour may prevent weight gain. While smoking is bad for the … Continue reading →

The Compartments of Energy And The Energy Balance Fallacy

Posted on December 5, 2014 by Robert Barrington

The energy utilised by the body is liberated from a number of separate compartments and can be measured as heat. In reality, body heat is measured as one unit, but for theoretical purposes it is convenient to compartmentalise this heat … Continue reading →

Cayenne Pepper And Protein For Weight Loss

Posted on May 29, 2014 by Robert Barrington

Forced calorie restriction is the current treatment for being overweight. The main problem with this approach however, is that it does not provide successful long term results. Initially, forced calorie restriction causes weight loss, but this has been shown to … Continue reading →

Weight Loss Lowers Resting Metabolic Rate

Posted on May 5, 2014 by Robert Barrington

It is a widely held belief amongst medical professionals and dietitians that weight gain is caused by small incremental accumulations of fat tissue due to a positive energy balance. This belief results in an associated belief that weight loss is … Continue reading →
