Washington, Apr 15 (ANI): A new study has found that having a low glycemic breakfast, which mostly includes fruits, before exercise can significantly enhance the benefits of working out.

A research team led by Dr. Emma Stevenson at the University of Nottingham sought to determine the effects of pre-exercise meal composition on fat metabolism in more typical (sedentary) individuals.

They found that blood glucose concentrations were higher after the having a high glycemic diet than the low glycemic meals.

It returned to baseline levels by the time exercise was commenced, after which they were not influenced by breakfast type.

They found that plasma free fatty acids (FFA; a marker for adipose oxidation) fell after consumption of both HGI and LGI breakfasts, but began to rise post-breakfast in the LGI treatment.

Exercise caused a rapid increase in FFA in both groups, but this was higher in the low glycemic diet compared to the high glycemic diet.

The authors concluded that consuming a LGI breakfast increases fat oxidation during subsequent exercise and improved satiety during recovery in sedentary females.

The findings are published in The Journal of Nutrition. (ANI)
