What is Dinitrophenol?

Dinitrophenol, also known as DNP, is a compound that was discovered to have weight loss properties during World War II. Workers in armory factories would incidentally ingest small amounts of it and began losing significant weight. This led to its popularity in niche circles like bodybuilding and modeling. However, DNP is highly dangerous and can be fatal. It affects the body by altering how neurons connected to fat cells regulate energy utilization, leading to increased body temperature and potentially fatal hyperthermia. Andrew Huberman strongly discourages its use due to these severe risks 1.
