Thermoregulation: The Key to Weight Loss

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

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

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

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

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

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

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

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

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

Aerobic Exercise: No Post-Exercise Thermogenic Effects

It is claimed that aerobic exercise is beneficial at causing weight loss. This claim is based largely on the ‘eat-too-much, do-too-little’ theory of obesity that explains weight gain in terms of an energy surplus caused by too much food and … Continue reading
