CBT applied to eating: 3 techniques I use with my patients
Cognitive Behavioral Therapy offers concrete tools to work with the thoughts that maintain a difficult relationship with food. Three techniques I apply in the consulting room.
Cognitive Behavioral Therapy (CBT) is the psychotherapy tool with the strongest evidence base for working with eating disorders and binge eating. I use it almost always in the consulting room, combined with a psychonutrition lens.
In this article I want to share three concrete techniques I apply over and over. They’re not magic formulas — they’re exercises that require practice — but used well they shift the relationship with food significantly.
1. Automatic thoughts log
CBT starts from a simple idea: we don’t react to events, we react to how we interpret them. When you eat “too much” at 11 pm, what triggers the behaviour isn’t the hunger itself, but the thought that appears immediately before.
The exercise is to write, during or just after the behaviour, three columns:
| Situation | Thought | Emotion (0-100) |
|---|---|---|
| 23:00, in the kitchen, looking at the fridge | “It’s ruined, I’m a mess” | Sadness 80, guilt 90 |
| At a party, saw a table with lots of desserts | “If I don’t eat anything I’ll look ridiculous” | Anxiety 75 |
The idea is not to judge the thought, but to see it written and notice that it’s a thought, not a fact. Many patients report that the simple act of writing it down drops the emotional intensity by 20-30 points.
2. Cognitive restructuring
Once the thought is written down, we can examine it. The classic CBT technique proposes asking yourself four questions:
- What’s the evidence for it? Is it really “a mess” to have eaten something off-plan?
- What’s the evidence against it? Are there other times I ate off-plan and nothing serious happened?
- What would I say to a friend in the same situation? We’re usually much more compassionate with others than with ourselves.
- Is there an alternative way to see it? For example: “I ate something that wasn’t in my plan. I didn’t like how I felt. Tomorrow I’ll go back to my routine without punishing myself.”
This technique doesn’t turn thoughts into positive ones (that’s not realistic). It turns them into more flexible and less absolute — which is what we need to stop falling into the all-or-nothing cycle.
A trick to make it easier: When you’re restructuring a thought, first write down the version your head tells you and then, in a separate column, the version you’d tell someone you love. The difference between the two is usually enormous.
3. Exposure with response prevention
This technique is for the cases in which a food has become “forbidden” in the head. The more forbidden a food is, the more you think about it.
The logic is the opposite of prohibition: include the food in a controlled way until it loses its emotional power.
The protocol, step by step:
- Choose one food that you’ve forbidden. Any one.
- Make a plan: when you’ll eat it, how much, in a way that isn’t a response to a binge.
- Eat it mindfully. Without guilt. Without compensating afterwards.
- Note what happened: did a binge erupt? Was it easier than you thought?
What usually happens, with repetition, is that the food loses its emotional charge. It stops being “the forbidden one” and becomes just… a food.
Important: this technique works best with professional accompaniment. If there’s an active eating disorder (anorexia, bulimia, recurring binge eating), it needs an adapted plan.
How to start today
If you want to start applying CBT to your relationship with food without waiting for a session, the most accessible option is the automatic thoughts log. Five minutes a day. Doesn’t require knowing much about CBT.
The Food & Mood Journal in the store includes a template designed exactly for this. It’s free and available in English.
If you feel the relationship with food is already affecting your daily life (you avoid social situations, you think about food most of the day, you eat until you feel physically ill), consider booking a consultation. Many people wait years before asking for help, and almost all of them, when they finally do, say: “I wish I’d done it sooner”.
Want to go deeper into CBT applied to eating? The CBT Applied to Eating mini-course is available in the store. Four video lessons with a downloadable workbook.
