Why Do I Not Get Hungry When I Work Out?
Digestion needs blood. Workouts send blood to muscles, not the digestive system. Exercise naturally slows digestion.
The vagus nerve sends brain impulses to the stomach to start digestion. Stress, worry, and intense activity can also activate this nerve.
Your liver and muscles store glycogen, a sugar. Glycogen is broken down for energy during exercise.
Cramps, headaches, and lethargy can result from dehydration. It might also make you bloated.
Hunger is signaled by ghrelin. It boosts appetite, food intake, and fat accumulation. Long workouts can boost or lower ghrelin, according to research.
Stress increases heart rate, blood pressure, respiration, and body temperature, which might affect hunger.
