In the 1960s, Russian-born doctor, Nicholas Bachynsky , learned of the effects of DNP while translating Russian medical journals for the US government. The Russians had used DNP to keep soldiers warm in winter with the main side effect being weight loss. In the early 1980s Bachynsky used this knowledge to set up clinics across the southern US promoting a weight loss treatment underpinned by DNP. Weight loss of up to 7kg a week was claimed with the only side effect being increased body temperature. About 14,000 patients enrolled on the programme and Bachynsky became very rich.
