Those molecules are ideally used as either immediate
energy fuel for your muscles and brain or converted to glycogen and stored in the liver and muscles as reserve energy.
As you already know, protein - rich food can rev up your metabolism,
provide fuel for the muscles and support greater fat loss — so when you simply can't wait for lunch to come, don't automatically reach for the chocolate bar.
During times of metabolic stress (such as weight training or other intense exercise), BCAAs may aid in protein synthesis,
become fuel for your muscles and prevent catabolism (muscle breakdown).
Starchy foods like pasta, rice, potatoes, sweet corn, cereal, bread, beans and so on are an important source of carbohydrates, the main source of
fuel for muscles during exercise.
Research supports the findings that this stops excessive muscular catabolism (breakdown) and helps store the protein as
fuel for the muscle tissue.
Coconut is a great source of medium chain triglycerides (MCTs), which are the best low
glycemic fuel for your muscles after exercise (I also recommend exercising in the morning, before your breakfast).
Oxygen is
fuel for the muscles.
Adrenaline is a shot of
fuel for your muscles.
So the main reason why bodybuilders need to focus on improving their insulin sensitivity is because without it, their bodies will tend to store more nutrients as fat instead of using them as
fuel for the muscles.
The body knows how to synthesize protein and turn it into energy and
fuel for your muscles.
The oxygen you take in enters the bloodstream and is carried to your muscles, where it is either used immediately or stored to break down glucose and create ATP energy — i.e.,
fuel for your muscles.
When your body is in a state of ketosis, it will begin to look for another source of
fuel for your muscles.
ATP is
the fuel for your muscle contractions.
Before exercise, the goal of nutrition is to provide a boost of
fuel for your muscles to burn for energy.
It is important to note that protein should be used as a source of tissue support, rather than energy, while carbohydrates and fats provide the majority of
fuel for the muscles.
