Dieting & cognitive performance


The research focused on the link between stress levels, cognitive function and the degree of support experienced during attempted weight loss.

It has been found that, during unsupported weight loss, salivary cortisol levels dramatically increase during the early stages of dieting, suggesting that the commonly seen impairments in cognitive function associated with dieting, are related to the stress experienced during attempted weight loss (Green, M. W., Elliman, N. A. & Kretsch, M. J. (2005). Weight loss strategies, stress and cognitive function: Supervised versus unsupervised dieting. Psychoneuroendocrinology. 30, 908-918).
