Recent clinical research studies evaluated metformin's potential effects as a weight-reducing drug in non-diabetic individuals despite its glucose-lowering effects. Metformin reduces weight by acting on the appetite regulatory pathways, peripheral fat metabolism, and averse unfavorable fat storage. Clinical recent findings indicated that individuals maintain weight with the help of lifestyle modifications and bariatric surgery. However, metformin's clinical efficacy on weight loss helped the individuals overcome overweight and obesity complications. Metformin alters the hypothalamic physiology, including insulin and leptin sensitivity. Furthermore, metformin regulates the circadian rhythm changes and gastrointestinal physiology by affecting food intake and regulating fat oxidation, storage fat in the liver, muscles, and adipose tissues. Research also indicated other appetite suppressing medications such as topiramate, lorcaserin, and phentermine along with metformin also seems logical but clinical data reported that their weight loss results are lacking. However, more detailed research on how metformin induces weight loss in non-diabetic individuals and the prescription of other pharmacological interventions is needed.

Cancerous patients, under the chemotherapy or radiotherapy, are at high risk of malnutrition due to the associated complications with the treatment procedures such as chewing problems, dysphagia, nausea etc. Considering the patients’ history of alcohol consumption, smoking or any other diseases and performing several physical examinations are essential in early identification of high-risk patients for nutritional complications, losing unintentional weight and fat free mass. In this review, we tried to briefly explain the risk of malnutrition in patients with head and neck cancers who are undergoing surgery, chemotherapy and radiotherapy. Oral nutrition, nasogastric tube and percutaneous endoscopic gastrostomy are different methods of nutritional interventions, which have been compared due to their efficacy in maintaining the patients’ weight. In this study, we reviewed the results obtained in clinical trials about the efficacy of intense nutritional intervention on limiting the chemoradiotherapy-associated complications in patients with head and neck cancers.
