Can running fasting to lose weight?

This is one of the questions that I have asked for more recent years ... what can bring us benefits run fasting?Each person usually has run its own quirks, some can not do it without listening to music on their headphones, others have applications that monitor calories and there are others who begin fasting day running.

 

What actually happens when we left to run on an empty stomach?

    What happens is that by not having sufficient carbon hydrates in the body for energy, your body begin to use stored fat to use them as fuel. Remember that our body always resort to get energy from carbohydrates consumed during the day, should it have no reservations, use its alternative source, lipids or fats.
    However, it is important to remember that if you usually run on an empty stomach have to do it in moderation because it is not the same as obtaining energy from carbohydrates to fat (the fat contribute less energy).This fasting running has its advantages, but like almost everything in life has its drawbacks:
