Increased Fat Oxidation<\/strong><\/span><\/h3>\n<p>Fasted cardio may enhance <strong>fat utilization as a fuel source<\/strong>. A 2016 study published in <em>British Journal of Nutrition<\/em> found that <strong>fat oxidation during exercise was significantly higher in a fasted state<\/strong> compared to a fed state (Schoenfeld et al., 2014).<\/p>\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>However, this does not necessarily translate to greater fat loss over time\u2014total energy balance remains the most important factor.<\/p>\n<\/blockquote>\n<h3 class=\"wp-block-heading\"><span id=\"2_Improved_Insulin_Sensitivity\"><strong>2.
