Article Synopsis
  • Previous research indicated that how much energy you burn through physical activity (AEE) plays a crucial role in how your body processes dietary fats, impacting body weight control.
  • The study assessed how different levels of physical activity affect the oxidation of specific dietary fats (saturated and monounsaturated) and insulin sensitivity in lean men over two months of training and one month of detraining.
  • Results showed that training increased the oxidation of dietary fats significantly, while a reduction in activity led to decreased fat oxidation, with strong correlations found between energy expenditure and fat metabolism markers.

The factors regulating the body's ability to switch from fat to carbohydrate oxidation in response to fuel availability changes, or metabolic flexibility (MF), are currently intensively investigated in the context of metabolic diseases. Although numerous metabolic diseases are associated with sedentary behaviors and metabolic inflexibility, the effect of habitual physical activity level (PAL) on MF regulation is surprisingly poorly known. We investigated how PAL affects MF in cross-sectional and interventional studies.
