MACMILLAN K, Norman. EXERCISE AND FAT BURNING: ¿TO EAT OR NOT TO EAT BEFORE TRAINING?. Rev. chil. nutr. [online]. 2009, vol.36, n.1, pp.72-74. ISSN 0717-7518. http://dx.doi.org/10.4067/S0717-75182009000100008.
The World Health Organization (WHO) has proposed to associate diet and exercise to handle the overweight prevalent in the population. The traditional exercise recommendation for fat burning is a moderate intensity session. In this condition fat oxidation during the activity reaches 6to 8 grams per minute, which is greatly diminished when previous carbohydrates is ingested. Another option recently studied as a strategy for managing overweight is strength training or intermittent high intensity efforts. In this condition glycogen depletion favors the use of adipose tissue as energy after the exercise. With this strategy it is not necessary fasting before training. Carbohydrates ingestion prior to the session will increase glycogen oxidation and promote greater fat oxidation after the exercise.
