Habits are formed by repeating actions over time. Forming new habits is difficult because transitioning away from old, comfortable habits causes anxiety. Our default eating habits, formed from psychological connections between cues and food, are hard to resist when stressed. Behavior modification aims to break these connections by identifying triggers for overeating and making a plan to avoid triggers or change routines. This includes eating slowly away from distractions, using smaller plates, and keeping healthy snacks available instead of leftovers.
