Conversely, continuous high-carbohydrate diets frequently promote lipogenesis and blunted insulin sensitivity. <strong>Carb Cycling<\/strong> provides the ultimate physiological synthesis: strategically modulating carbohydrate intake across high, moderate, and low-carb days to maximize muscle glycogen on demanding training days while driving aggressive fatty acid oxidation on rest or recovery days.

Consuming high quantities of dietary fats alongside high carbohydrates provides the exact biochemical environment for rapid adipose storage.
