The glucose response to acute calorie restriction was heterogeneous in the long‐duration group with some responding similarly to those in the short‐duration group, some responding, but only slowly, and others not responding at all. Overall, HbA<sub>1c</sub> concentration in the short‐ vs. long‐duration groups fell to 44 ± 2 vs. 64 ± 6 mmol/l (6.2 ± 0.2 vs. 8.0 ± 0.5%; <italic>P </italic>=<italic> </italic>0.002). Fasting plasma glucose levels decreased to 5.8 ± 0.2 vs. 8.4 ± 1.1 mmol/l (<italic>P </italic>=<italic> </italic>0.024) respectively. A total of 87% of the short‐duration group and 50% of the long‐duration group achieved non‐diabetic fasting plasma glucose levels at week 8.
