In a new study, researchers at Uppsala University now demonstrate that one night of sleep loss has a tissue-specific impact on the regulation of gene expression and metabolism in humans. This may explain how shift work and chronic sleep loss impairs our metabolism and adversely affects our body composition. The study is published in the scientific journal  Science Advances . Epidemiological studies have shown that the risk for obesity and type 2 diabetes is elevated in those who suffer from chronic sleep loss or who carry out shift work. Other studies have shown an association between disrupted sleep and adverse weight gain, in which fat accumulation is increased at the same time as the muscle mass is reduced -- a combination that in and of itself has been associated with numerous adverse health consequences. Researchers from Uppsala and other groups have in earlier studies shown that metabolic functions that are regulated by e.g. skeletal muscle and adipose tissue are advers...

So you think that you really need food to get you through a workout? According to some articles, the thought of loading up on carbohydrates has been called into question. It is true that having carbs before a workout is good and it might even increase performance but what I have read lately it also says that it stops the body from using that stored fat for the needed energy. Fasted is the optimal state to workout because during that time the body releases insulin to lower the blood sugar, proteins and fats that are absorbed by our digestive system so that the glucose can be transported to muscles and be used for energy. So now that you know....what are you going to do? It is ok to workout fasted or if you prefer to have your normal intake of pre-work out or protein before the workout....now you know it is ok.
