Plain English Summary

Background and study aims
Reactive hypoglycemia (RH) is a disorder where levels of glucose (sugar) in the blood become dangerously low following a meal (called hypoglycemic episodes). Nutritional therapy is recommended for people affected by RH. The macrobiotic Ma-Pi 2 diet is a nutritional therapy that improves glucose control in people with type 2 diabetes. The aim of this study is to investigate whether the Ma-Pi 2 diet improves blood glucose levels in patients affected by RH.

Who can participate?
Patients diagnosed with RH, aged 26 to 65.

What does the study involve?
Patients are randomly allocated to one of two groups. One group receives the control (low-glycemic index) diet for 3 days followed by the macrobiotic Ma-Pi 2 diet for a further 3 days. The other group receives the Ma-Pi 2 diet and then the control diet. All participants' blood glucose levels are measured throughout the study by using continuous glucose monitoring devices and glucometers.

What are the possible benefits and risks of participating?
There may be immediate direct benefits to the subjects participating - i.e. reduction of the number of hypoglycemic episodes. The main risk could be a drastic decrease in glucose levels and to avoid it participants will be strictly monitored by the doctors and specialists involved.

Where is the study run from?
The Endocrinology Area of the University of Campus Biomedico of Rome (Italy).

When is the study starting and how long is it expected to run for?
February 2014 to February 2015

Who is funding the study?
UPM Un Punto Macrobiotico International Association (Italy)

Study information

Scientific title

A randomized crossover trial to assess the effect of the Ma-Pi 2 MAcrobiotic diet in the treatment of reactive HYPoglycemia with continuous glucose monitoring system (MAHYP)



Study hypothesis

This study is designed to determine whether short-term administration of the macrobiotic Ma-Pi 2 diet improves metabolic control in non-diabetic subjects affected by reactive hypoglycemia (reduction of the number of hypoglycemic episodes and assessment of glycemic distributions through different readings by continuous glucose monitoring system) compared with a low-GI diet for reactive hypoglycemia – to date, there is no diet for treating this condition.

The null hypothesis is that there will be no reduction of the number of hypoglycemic episodes or that there will be no difference according to the dietary sequence administered.

Reactive hypoglycemia


The subjects enrolled in the study are randomized and consequently divided into two homogeneous groups to receive the two dietary treatments in opposite sequence. Over a period of 6 days they are lodged in a farm in Italy, where they receive all daily meals (Ma-Pi 2 Macrobiotic meals or a control low-GI diet for reactive hypoglycemia).
Anthropometrical measurements will be carried out at baseline and after 6 days of the dietary interventions. Glucose profile measurements will be performed throughout the trial by using continuous glucose monitoring and glucometers.

Drug names

Primary outcome measures

Reduction of the number of episodes of reactive hypoglycemia (blood glucose level below 70 mg/dL) in patients affected by such condition during macrobiotic Ma-Pi 2 diet administration compared to a same period during the administration of a low-GI diet.

Secondary outcome measures

Glycemic distributions assessment through different readings (< 40; 41-50; 51-60; 61-70, 71-80, 81-90, 91-100, 101-110, 111-120, 121-130, 131-140, 141-150, 151-160, 161-170, 171-180 and > 180 mg/dL), measured and compared between the two dietary treatments
