Weight Loss and Cognitive Function in Adults

Weight Loss and Cognitive Function in Middle-Aged and Older Adults

More than two-thirds of middle-aged and older adults are overweight, which places them at greater risk of disability and higher medical expenses. Lifestyle interventions which promote weight loss for this population are needed. However, it is not known how different weight loss approaches impact brain (cognitive) functions, such as memory and attention. The investigator's investigation aims to improve adherence to a hypocaloric diet prescription through improved attention and inhibitory control, reduced hunger, and increased satiety.

The objectives of this pilot study are to: 1) determine the feasibility and establish proof-of-concept; 2) establish proficiency and feasibility of the proposed cognitive function assessments; and 3) obtain preliminary data for effect size generation.
