Thought distortions are common, predictable patterns of unhelpful thinking, such as all-or-nothing thinking, catastrophising and “should” statements. They often show up around food and exercise, and they can turn a small slip into a week of giving up. The skill to practise is spot it, name it, reframe it: notice the thought, label which distortion it is, then replace it with a more balanced and useful version. Below are the most common ones, with real food and exercise examples and a short exercise for each.
Why naming the distortion helps
Cognitive behavioural therapy (CBT) is based on the idea that thoughts, feelings and actions are linked. The NHS describes CBT as including questioning unhelpful thoughts and beliefs, and considering other ways of looking at things. NHS Every Mind Matters teaches a simple self-help version called “catch it, check it, change it”, and notes that knowing what sort of thinking is unhelpful makes it easier to spot. Once you can name a pattern (“that’s catastrophising”), it loses some of its grip.
How to use this article
Pick one distortion a week. Each time you notice it, write down three things:
- The thought, word for word.
- Its name from the list below.
- A balanced reframe: true, kind and useful.
By the end of the month you’ll have a personal list of reframes ready to use.
1. All-or-nothing thinking
Seeing things as completely good or completely bad, with nothing in between.
- “I had a doughnut at the meeting, so today is ruined.”
- “If I can’t do the full hour at the gym, there’s no point going.”
Reframe: “One doughnut is one food choice. My next meal can be a balanced one.” “A 20-minute workout still counts.”
Exercise: When you notice the thought, list three options between “perfect” and “nothing”. More practice: how to stop all-or-nothing thinking in your diet.
2. Overgeneralisation
Taking one event and turning it into a rule with words like “always” and “never”.
- “I overate at the party. I always lose control around food.”
- “My knee hurt on that run. I’ll never be a runner.”
Reframe: “I overate at this party. At the last two, I did fine.” “My knee hurt today; I’ll rest it and get it checked if it keeps hurting.”
Exercise: Circle every “always” and “never”. Find one exception.
3. Mental filter
Focusing only on the negative and filtering out everything that went well.
- Ignoring five days of good meals and fixating on one takeout supper.
- Seeing only the part of your body you dislike in a photo.
Reframe: “Five out of seven suppers were home-cooked. That’s a strong week.”
Exercise: At the end of each day, write down three things that went well with food, movement or rest before you write any criticism.
4. Discounting the positive
Admitting good things happened, but deciding they don’t count.
- “I walked every day this week, but that’s easy; it’s not real exercise.”
- “I lost two pounds, but it’s probably just water.”
Reframe: “Walking every day is a habit I didn’t have a month ago. It counts.”
Exercise: When you hear yourself say “but”, stop the sentence before it.
5. Catastrophising
Jumping to the worst possible outcome.
- “I gained a pound this week. Everything is falling apart.”
- “I missed my workouts while I was sick. I’ve lost all my progress.”
Reframe: “Weight goes up and down day to day. A week off doesn’t erase months of training.”
Exercise: Ask: “What’s the worst case, the best case and the most likely case?” Plan for the most likely one.
6. Jumping to conclusions
This comes in two forms. Mind reading means assuming you know what others think. Fortune telling means predicting the future as if it’s certain.
- “Everyone at the gym is staring at me and judging.”
- “I’ll never stick to this, so why start?”
Reframe: “Most people at the gym are focused on their own workout.” “I don’t know how this will go. I can try it for two weeks and see.”
Exercise: Write down the evidence for and against the thought, as if you were a fair judge.
7. Emotional reasoning
Treating a feeling as if it were a fact.
- “I feel like a failure, so I must be one.”
- “Learning to cook feels overwhelming, so it’s not for me.”
Reframe: “I feel discouraged right now. Feelings are real but they aren’t facts.” “Overwhelm means it’s new. I’ll start with one simple recipe.”
Exercise: Add “I’m having the feeling that…” in front of the thought. Notice how it changes.
8. “Should” statements
Rigid rules about how you or others must behave, often followed by guilt.
- “I should never eat dessert.”
- “Fit people ought to look a certain way.”
- “I should be at the gym every day.”
Reframe: Swap “should” for “could” or “I’d like to”. “I’d like to move most days. Today a walk works.”
Exercise: List your food and exercise “shoulds”. For each one, ask: “Who made this rule, and is it helping me?”
9. Labelling
Attaching a harsh label to yourself because of one action.
- “I ate the whole bag of chips. I’m disgusting.”
- “I forgot my gym clothes again. I’m such an idiot.”
Reframe: Describe the behaviour, not your worth. “I ate more than I planned while I was stressed. Next time I’ll plan a snack before that meeting.”
Exercise: Ban name-calling for a week. Every time a label shows up, rewrite it as a specific, fixable action.
10. Personalisation
Blaming yourself entirely for things that have many causes.
- “The whole family ate takeout tonight because I didn’t plan well enough.”
- “My trainer looked frustrated; I must be the worst client.”
Reframe: “It was a busy week for everyone. Takeout once is fine, and I can plan an easy freezer meal next time.”
Exercise: Draw a pie chart of everything that contributed to the outcome. Your slice is usually smaller than you think.

When to check with a professional
If negative thoughts about food, weight or your body are constant, affect your mood most days, or come with restricting, bingeing or compensating behaviours, talk to your doctor or a mental health professional about CBT or other support. In Canada, NEDIC offers a free helpline for food and body concerns.
Key takeaways
- Thought distortions are common and predictable; naming them weakens them.
- Use spot it, name it, reframe it, and write all three down.
- Good reframes are true, kind and useful, not forced positivity.
- Focus on one or two distortions a week.
- Describe behaviours instead of labelling yourself.
