Bad breath from drinking weight-loss coffee may be due to excessive caffeine intake, which irritates the mouth and leads to halitosis. Alternatively, frequent consumption of weight-loss coffee may cause internal heat, triggering conditions such as periodontitis that result in bad breath. It could also be caused by caffeine in the weight-loss coffee inhibiting gastrointestinal motility, reducing saliva secretion, and allowing large amounts of bacteria to grow in the mouth.
