why the gut

The digestive system is part of the gut and is responsible for ingestion of the food, the release of digestive enzymes and juices, and transport of food and subsequent waste through the body, and the breakdown of food into smaller pieces during digestion. The digestive system uses the food that you feed it to produce energy, but if you are consuming food with a poor nutritional profile it may be taking more energy to process than it is giving to your body. Which sounds like a weightloss dream scenario, but in actual fact it is draining you of energy making you feel tired and hangry.
