Popis: | Overweight and obesity are often theorized using the energy balance equation. When energy intake (EI) is greater than energy expended this creates a positive energy balance and leads to weight gain, conversely when energy expenditure (EE) exceeds EI this creates a negative energy balance and weight loss. Physiologists have been examining the relationship between EE and EI since the 1950s. Total daily EE is comprised of two main components; resting metabolic rate (RMR) and physical activity (PA). This review will examine and report the relationships between both major components of EE and EI, and therefore the impact of PA on body weight. The relationship between energy expended through PA and EI appears to be weak, especially within one day and over longer periods in overweight and obese adults. However, recent data have demonstrated a strong relationship between RMR, hunger and food intake. The differences observed in the relationships between PA EE and EI and metabolic EE and EI are not surprising. EE from PA is highly variable and episodic whereas EE from RMR is very stable and tonic. These new data provide evidence for a fundamental link between EE and EI. |
