When the body enters starvation mode during fasting, it switches from using glucose to burning stored fat, a process called ketosis. This shift can lead to both physical and mental effects, such as increased energy, mental clarity, or in some cases, fatigue and hunger pangs. Each individual’s experience with starvation mode and ketosis during fasting can vary.
