Dieting Alone Won’t Do It
Evidence from researchers at Oregon Health & Science U indicates that dieting alone does not result in significant weight loss. Scientists believe this is due to the body’s compensatory mechanism of reducing its level of physical activity when caloric intake is reduced. For the study, primates ate high fat diets for several years and then were placed on calorie reduced diets while scientists tracked their activity levels. While there was no significant weight loss while on the low fat diet, the monkeys’ activity levels were dramatically reduced. The scientists, writing in the American Journal of Physiology - Regulatory, Integrative and Comparative Physiology, believe this is due to the body’s natural reaction of reducing activity levels in response to reduced caloric intake.
