Notice the lie after a binge
After a binge, people often tell themselves “I’ll start dieting again tomorrow”—but then the cycle repeats. This isn’t just lack of willpower; several psychological and biological mechanisms are involved.
1. The brain tries to reduce guilt (cognitive dissonance)
After a binge, people often feel a conflict between:
- “I want to control my eating.”
- “I just ate a lot more than I planned.”
This mental discomfort is called Cognitive Dissonance.
To reduce that uncomfortable feeling, the brain creates a comforting story:
“It’s okay, tomorrow I’ll be strict again.”
That promise temporarily reduces guilt, even if it isn’t realistic.
2. Restriction increases the chance of another binge
Many binges happen after strict dieting or food restriction. When you plan to “diet harder tomorrow,” you’re often planning more restriction.
But restriction triggers:
- stronger hunger hormones
- increased food obsession
- stronger reward response to food
This biological pressure makes the next binge more likely, which is a core part of Binge Eating Disorder patterns and similar cycles.
3. The “fresh start effect”
Humans like the idea of starting over.
Psychologists call this the Fresh Start Effect—the belief that:
- tomorrow
- Monday
- next week
- next month
will somehow make behavior easier.
After a binge, saying “tomorrow I’ll be perfect again” gives a feeling of control, even though nothing actually changes overnight.
4. Short-term comfort vs long-term reality
The brain often chooses short-term emotional relief over long-term change.
Right after a binge:
- guilt and shame are high
- promising a future diet reduces those feelings quickly
But that promise doesn’t address the underlying triggers (restriction, stress, emotional eating, etc.).
5. All-or-nothing thinking
Many people approach food with extreme rules:
- “I must eat perfectly.”
- “I ruined the day.”
- “I’ll restart tomorrow.”
This pattern is linked to All-or-Nothing Thinking, a cognitive distortion where anything less than perfect feels like failure.
So after one binge, the brain decides the day is already “lost.”
6. Dopamine and reward learning
Highly palatable foods trigger the brain’s reward system.
This involves Dopamine, which reinforces behaviors that feel rewarding. If binge eating temporarily relieves stress or emotions, the brain learns that binging works, even if it causes regret later.
