Competing response training means choosing a specific action that is hard to do at the same time as snacking, and doing it as soon as you notice the urge. Because snacking usually involves your hands, your mouth and your attention, the most useful replacements keep one or more of those busy for a few minutes while the urge passes. The method has two parts: learn to notice the urge early, then practise your replacement every time until it becomes the new habit.
Where this idea comes from
Competing response training is borrowed from habit reversal, a behavioural approach first developed for nervous habits such as nail-biting and tics. A review of the research found that awareness training and the use of a competing response were the essential components of habit reversal. Mindless snacking is not the same as a tic, but it shares the same structure: a cue, an automatic action and a quick reward. That makes the two core skills, noticing and replacing, a practical fit.
This is a tool for unplanned, automatic snacking. It is not about skipping meals or planned snacks. If you are physically hungry, eating is the right response.
Step 1: Build awareness of the urge
You cannot replace a habit you do not notice. For one week, track each unplanned snack with four quick notes:
- Cue: what was happening right before (opening the pantry, sitting down to TV, finishing a work call)?
- First sign: what was the earliest thing you noticed (a thought, reaching for the cupboard, a feeling in your body)?
- Feeling: bored, tired, stressed, rewarded, restless?
- Hunger rating: 1 (starving) to 10 (stuffed).
The aim is to catch the urge earlier each time. At first you may only notice once the food is in your hand. Over a week or two, many people start catching it at the thought or the first step toward the kitchen. That earlier moment is where your competing response goes.
Stress is a common driver. Harvard Health notes that ongoing stress raises cortisol, which increases appetite and may ramp up motivation to eat, and that keeping “comfort foods” handy makes stress eating more likely. If your log shows stress as a frequent cue, pair your replacement with something calming.
Step 2: Choose your replacements
A good competing response is easy to start, physically gets in the way of snacking and takes two to five minutes. Pick at least one from each category below so you have options in different settings.
Hands replacements
- Squeeze a stress ball or putty.
- Knit, crochet or do a small craft.
- Fold laundry or tidy one drawer.
- Hold a water bottle and drink from it.
- Do a quick hand stretch: clench and spread your fingers ten times.
- Write a short list or doodle on a notepad.
- Do a page in a puzzle book.
Mouth replacements
- Brush your teeth or use mouthwash. Most foods taste off afterward, which is a helpful signal that eating time is over.
- Sip a glass of cold water or sparkling water.
- Make a cup of herbal tea such as peppermint, rooibos or chamomile.
- Chew sugar-free gum.
- Hum, sing along to a song or call a friend.
Mind replacements
- Name the feeling in one or two words (“restless,” “drained”).
- Take five slow breaths, counting each exhale.
- Do a short puzzle such as a crossword or word game.
- Read two pages of a book.
- Ask: “Am I hungry, or do I want a break?” If it is a break, take one that is not food.
Step 3: Match replacements to your cues
The best response depends on the situation. Use your awareness log to build a simple match-up table. Here is an example:
| Cue | Competing response | Why it fits |
|---|---|---|
| Sitting down to watch TV | Knitting or a stress ball in hand, water bottle beside you | Keeps hands busy for the whole show |
| After dinner, wandering into the kitchen | Brush teeth right after the dishes | Signals the end of eating for the day |
| Mid-afternoon at the desk | Stand, stretch, refill water, five slow breaths | Breaks up sitting and restores focus |
| Driving home | Sing along to music, sip water | Keeps mouth busy until you are home |
| Feeling stressed | Name the feeling, then a two-minute walk | Addresses the stress, not just the urge |
Step 4: Practise until it is automatic
The first few times, the replacement will feel like effort. That is normal. Habits form through repetition in the same situation. A review of habit-formation research explains that repeating a chosen behaviour in the same context until it becomes automatic is the core of building a new habit, and that missing an occasional opportunity did not seriously set back progress.
Practical ways to get those repetitions in:
- Stage the tools. Put the stress ball beside the remote, the toothbrush within reach after dinner, the herbal tea next to the kettle.
- Rehearse once when calm. Walk through the cue and the response on purpose a few times so it is familiar.
- Hold it for a few minutes. Many urges ease if you give them a short window. Set a five-minute timer and do the replacement until it rings.
- Decide after. When the timer goes off, check in. If you are actually hungry, have a planned snack. If not, carry on.
Pair these with a few if-then plans for high-risk windows so the response is decided before the urge shows up.
Step 5: Make the old habit harder
Competing responses work better when the environment helps:
- Store snack foods out of sight, or in opaque containers on a high shelf.
- Keep a ready-to-eat planned snack (cut vegetables and hummus, fruit, yogurt) at eye level for real hunger.
- Avoid eating in front of screens, which blurs the link between eating and attention.
- Buy single portions of treats you enjoy rather than family-size bags.

Troubleshooting
“I forget to do it.” Make the tool visible at the cue location. A stress ball you cannot see will not get used.
“The urge comes back after the timer.” Try a different category. If hands did not help, try mouth or mind. Or check whether you are actually hungry and need a proper snack.
“I gave in.” Note what happened in your log without judging it. One slip says nothing about the next attempt.
Quick takeaways
- Track unplanned snacks for a week to find cues and the earliest sign of the urge.
- Pick at least one hands, one mouth and one mind replacement.
- Match replacements to specific cues and keep the tools within reach.
- Hold the replacement for about five minutes, then check true hunger.
- Repeat in the same situations until it feels automatic.
FAQ
Isn’t this just distracting myself?
Partly, but with a plan. The replacement is chosen in advance, matched to a cue and repeated until it becomes a new habit, which is different from hoping a distraction comes along.
What if I am actually hungry?
Eat. Competing responses are for automatic snacking, not real hunger. A regular pattern of satisfying meals makes the true-hunger check much easier.
