Diet plays a critical role in RH, as the types and timing of food consumption impact blood sugar levels. Evidence suggests that avoiding meals high in simple carbohydrates, refined sugars, and alcohol consumption may reduce RH symptoms. [1][2][3] Meal composition, balance, frequency, timing, and portion size are some of the most commonly cited methods of controlling blood sugar fluctuations.[4] Evidence also suggests that diets that manage glycemic control and/or contain high fiber may also be helpful under the right circumstances.[5][6] However, due to the potential variability in underlying causes of RH, these dietary adjustments may not be suitable for everyone.

Diet significantly influences reactive hypoglycemia (RH) by affecting blood sugar levels; therefore, limiting the intake of high simple carbohydrates, refined sugars, and alcohol is a key recommendation. Additionally, meal composition, timing, and fiber content can help manage symptoms, though dietary adjustments may vary based on individual causes of RH.
