Time Restricted Eating Plus Exercise for Weight Management

Cognitive Decline Clinical Trial

Official title: Time Restricted Eating Plus Exercise for Weight Management

Status Active, not recruiting

Clinical Trial Summary

Time restricted eating (TRE) is currently the most popular form of intermittent fasting which involves confining the eating window to 8-10 hours (h) and fasting for the remaining hours of the day. TRE is unique in that during the eating window, individuals are not required to count calories or monitor food intake in any way, resulting in high adherence. Accumulating evidence suggests that TRE produces a natural energy deficit of ~350-500 kcal/d. Physical activity in combination with a healthy diet pattern is recommended for older adults. While aerobic type exercise is the most commonly recommended, retention of lean mass via resistance training, especially in older adults, may be more effective at improving mobility, neurological and psychological function, executive and cognitive functioning, and processing speed. TRE combined with physical activity has not been examined in older adults or in people with overweight or obesity. This study holds the potential to 1) decrease body weight 2) improve lean mass 3) improve insulin sensitivity, and 4) improve attention, executive functioning, and processing speed in older adults. The aims of this study will examine the effect of TRE combined with either resistance training or aerobic training on body weight, body composition, metabolic disease risk, and cognition in adults over age 50. It is hypothesized that the TRE combined with resistance training group will see the most significant improvements in body composition, insulin sensitivity and cognition due to lean mass accretion.
