Reversal of Diabesity: Normalization of Insulin Release Curve in Association with Reversal of Non-Alcoholic Fatty Liver Disease.

OBJECTIVE: Type 2 diabetes with obesity is regarded as an incurable, progressive disease with many complications. The hypothesis was tested that glycated haemoglobin (HbA1c) and the insulin release curve can be restored by traceable systematic methods. METHODS: 122 people with diabesity were investigated before and after three and 6 months of traceable systematic management methods. Basal body mass index (BMI), fatty liver, HbA1c, and insulin release curve were measured. RESULTS: After 3 months of traceable systematic management, BMI decreased from 30.76 ± 0.48 to 21.86 ± 0.09 kg/m2 (p < 0.001) and remained stable during the last 3 months (21.82 ± 0.09 kg/m2 at 6 months). Colour Doppler ultrasound showed non-alcoholic fatty liver disease (NAFLD) in all diabesity participants at baseline. At 3 months, only one participant had low-grade fatty liver, and fatty liver was reversed in other participants (p < 0.001). The number and grade of fatty liver at 6 months were the same as at 3 months. Fasting plasma glucose decreased and continued to decrease thereafter (p < 0.001). Two-hour postprandial plasma glucose decreased and continued to decline until 6 months (p < 0.001). HbA1c also decreased and maintained this level at 6 months. At baseline, the peak value of insulin release was 1,141.09 ± 43.02 pmol/L at 2 h after meals, and the early phase of insulin secretion was lost. After 3 months of management, the insulin concentration was 621.62 ± 19.32 pmol/L at 2 h after meals. After 6 months, the value decreased, and the early phase of insulin secretion recovered. CONCLUSIONS: Normalization of the insulin release curve in type 2 diabetes was achieved by traceable systematic methods. This was associated with recovery from NAFLD. Diabesity is reversible by traceable systematic management.
