Too tired to be healthy? You're not alone, survey finds

Feel too tired to work out? No motivation to eat your greens? You're not alone. Low motivation and fatigue are the primary factors keeping people from adopting a healthy lifestyle, a British survey suggests.

The poll of 2,086 adults was conducted online by YouGov on behalf of the World Cancer Research Fund and published Wednesday. It asked people what prevented them from making healthy changes to diet and being more physically active.
