Fat Oxidation
Fat oxidation is the process of breaking down fat to produce energy.
Fat oxidation increases when insulin levels are lower and glycogen stores are reduced. This happens during fasting or when food intake is controlled. Over time, consistent fat oxidation contributes to fat loss. The key is maintaining the conditions that support it across days and weeks.
