Studies have shown that training in a fasted state has the potential to tap into stored fat for fuel i.e. using fat reserves for energy. The logic behind this is that after a night-long fast, one’s blood sugar and liver glycogen stores are low, and thus the body uses stored fat for energy. Research has pointed out that fasted training is effective and doesn’t hinder performance, provided that one trains at the right intensity and/or duration. To begin try to figure out an optimal duration and pace by fasting for 12-14 hours and following it with a longer duration, low intensity ride. Some important points to keep in mind when it comes to fasted riding, is to keep well hydrated - drink a cup of black coffee/tea/ green tea or water before your ride and carry a bottle of water on your ride.
