@thesashafischer: When you are metabolically flexible, your body is able to switch between fuel sources such as carbs and fats to maximise efficiency. When you go long periods without food, your body shifts gears to rely on different fuel sources, such as glycogen breakdown, protein breakdown for glucose, and fatty acid oxidation. #1 telltale sign of metabolic inflexibility is the “hanger” and a need of frequent snacking. #weightlosscoaching #bloodsugarbalance #intermittentfastingforbeginners
