– Declining beta-cell function
– Relationship between insulin resistance and decline in beta-cell function
– Two types of prediabetes: a) elevated fasting BG but normal OGTT, b) normal fasting BG but elevated 2 hour OGTT
– Postprandial glucose excursions
– Can type 2 diabetes be reversed? Remission vs. reversal
– Diabetes Remission Clinical Trial (DiRECT)
– VIRTA health trial
– Nutritional interventions: weight loss, carbohydrate restriction, fasting, etc.
– Weight loss: why does it lead to remission or improvement in biomarkers?
– Best blood markers to monitor?

Nicola has a particular interest in the use of low-carbohydrate diets in the management of type 2 diabetes, and leads a research programme investigating dietary modification – including increasing protein or the use of very-low-calorie-diets – on the factors underlying type 2 diabetes.
