Answer to Question 1

TRUE

Answer to Question 2

During the process of modifying unhealthy eating behaviors, relapses into past negative behaviors are almost inevitable. The three most common reasons for relapse are:
1 . Stress-related factors (e.g., major life changes, depression, job changes, and illness).
2 . Social reasons (e.g., entertaining, eating out, and business travel).
3 . Self-enticing behaviors (e.g., placing yourself in a situation to see how much you can get away with: One small taste won't hurt leads to I'll eat just one slice and finally to I haven't done well, so I might as well eat some more.)
