Try Unimate, water, or other very low-calorie drink options during your fasting period. Remember that our bodies are capable of storing ample amounts of energy in the form of glycogen and fat to sustain our daily activities and more. However, our bodies may not be as practiced at accessing energy stored in the form of fat, because they are instead adapted to having a constant supply of glucose from high-calorie convenience foods due to our habits of constant snacking and late-night eating. Allow your body up to one month to adapt to intermittent fasting and retrain itself to become more metabolically flexible.
Try to identify the root of your craving. If the craving is based on simply eating unhealthy foods and not to satisfy your hunger, find ways to limit your exposure or desire to aforementioned foods. In addition, other types of foods can increase levels of satiety or fullness when consumed. During your eating window, try to limit the amount of nutrient-poor foods while maximizing healthy, calorically dense, and nutrient-rich foods. Experiment with different types and amounts of food until you find the regimen that works best for you.
