Intermittent Fasting in Diabetic Patients

Obesity is becoming increasingly prevalent worldwide. It is linked to health problems including cardiovascular disease, diabetes, cancer, musculoskeletal problems and even psychiatric problems. Intermittent fasting is an interventional strategy wherein individuals are subjected to varying periods of fasting. Intermittent fasting has recently attracted attention because experimental studies have highlighted its potential for correcting metabolic abnormalities. Preliminary findings indicate that intermittent fasting may be associated with increased lifespan, decreased mortality from cancers and cardiovascular diseases, improved insulin sensitivity, and reduced oxidative stress and inflammation. However, some of the data still remain controversial. No human studies have examined the effects of intermittent fasting in diabetics. Studies examining intermittent fasting in diabetic patients have encountered problems with compliance, malnutrition, and hypoglycemia rather than seeing benefits of weight loss. Regular meals (at least three meals each day) and a balanced diet are crucial in the management of blood sugar levels in diabetic patients.
