The Weight Loss Effects of Alcohol

Posted on February 24, 2014 by Robert Barrington

We are told by the ‘experts’ who control our lives that when we get fat it is because we eat too much and do too little. This ‘eat-too-much, do-too-little’ theory of weight gain is ‘common knowledge’ to most and so … Continue reading →

Thermogenic response to Fat: Obesity

Posted on February 20, 2014 by Robert Barrington

The ‘eat-too-much, do-too-little’ theory of obesity claims that weight gain is a simple case of a positive energy balance. Too much food and too little exercise is said to cause a small but constant accumulation of stored energy that over … Continue reading →

Postexercise Energy Expenditure from Aerobic Exercise

Posted on February 8, 2014 by Robert Barrington

  The energy balance equation suggests that body weight is determined by the amount of calories consumed and the amount of exercise performed. However, this equation does not represent the true picture because it does not account for the ability … Continue reading →

Energy Balance: A Complex Subject

Posted on February 6, 2014 by Robert Barrington

  The energy balance equation is often used to justify that weight gain and obesity is caused by too much food and too little exercise. This ‘eat-too-much, do-too-little’ hypothesis of weight gain blames the individual for their excessive body fat. … Continue reading →

Energy Restriction Diets Fail

Posted on January 27, 2014 by Robert Barrington

  Energy restriction diets do not cause successful long term weight loss. Despite this energy restriction diets are still considered the only way to cause weight loss by many people, including those in the medical establishment. While weight loss is … Continue reading →

Thermic Effect Of Food and Energy Expenditure

Posted on January 18, 2014 by Robert Barrington

  The thermic effect of food (TEF) is the postprandial rise in energy expenditure that is due to the processing of ingested food. It was first shown by Seguin and Lavoisier in 1793 when they measured an increase in oxygen … Continue reading →

Energy Expenditure In More Detail

Posted on January 17, 2014 by Robert Barrington

  Daily energy expenditure is composed of three main components, the resting metabolic rate (RMR), the thermic effect of food (TEF) and the thermic effect of activity (TEA). The resting metabolic rate is the energy required by the body to … Continue reading →

Protein Versus Carbohydrate Versus Fat: Energy Considerations

Posted on December 11, 2013 by Robert Barrington

Altering the ratio of the macronutrients can have a strong influence on the prevailing metabolic energy balance because protein, carbohydrate and fat are metabolised quite differently. Postprandially, protein can increase thermogenesis by 25 to 40 %, glucose by 6 to … Continue reading →

Forced Calorie Restriction: More Evidence of Metabolic Damage

Posted on November 16, 2013 by Robert Barrington

Forced Calorie restrictive diets that attempt to coerce the body into accepting a lower level of fat mass are dangerous and do not work. That they cause metabolic damage is well evidenced in the scientific literature. Such dietary regimens are … Continue reading →

Thermic Effect of Food Blunted in Vegetarians?

Posted on August 18, 2013 by Robert Barrington

he thermic effect of food (TEF) is the increase in body heat produced following a meal. This can be measured in a laboratory setting and gives some indication as to the amount of energy that the body is prepared to … Continue reading →
