David John Hume, aged 25, is a final year Ph.D student (University of Cape Town, South Africa) aspiring to enroll for post doctoral study in 2015. Obesity research has always been his main interest with his work primarily focusing on the factors which predispose individuals to weight regain (or “weight loss relapse”) after successful weight reduction. His publications include work on resting and activity-related thermogenesis in formerly overweight women; the socio-cultural, environmental and behavioural determinants of obesity in black South African Women; the role of adipose tissue in insulin resistance in women of African ancestry; the metabolic effects of African bird’s eye chilli in overweight individuals; and electrophysiological (EEG) response to visual food cues in obese and overweight women.


Heightened brain-reactivity to food cues, as measured by differences in attentional bias during the early and maintained phases of information processing, may relate to a higher Body Mass Index (BMI). The present study explored differences in the attentional processing of visual food-related versus neutral stimuli in obese, overweight and normal weight women
