UK scientists identified 6 types of obese individuals based on a new study: 1) young male heavy drinkers, 2) unhappy/anxious middle-aged adults, 3) happy older adults with health conditions, 4) young healthy females, 5) older affluent healthy adults, and 6) individuals with very poor health. The study concluded strategies for weight loss should be tailored to the individual's type. Researchers suggested messages about alcohol reduction could help young adults while exercise and counseling could benefit unhappy middle-aged adults.
