HOW TO COMBAT SNACKING

Why willpower doesn’t stop you from snacking.

You've done it. We've all done it. A perfectly on-track day, solid meals, macros in check — and then 4pm hits and you're somehow elbow-deep in a bag of chips you had no intention of touching. The internal monologue that follows is predictable: why can't I just have more discipline?

Here's the thing. Discipline has almost nothing to do with it.

Your brain isn't hungry. It's tired.

Snacking is rarely about physical hunger. What it's almost always about is mental fatigue looking for the quickest available source of pleasure. A bit like a wank, but with eating

Your brain runs on two systems: 

One is fast, automatic, and pleasure-seeking; the other slow, deliberate, and rational. 

Self-control is the slow system keeping the fast one in check. And after a long morning of emails, decisions, and cognitive load, the slow system is running on fumes.

So when 4pm arrives and the leftover cookie dough sourdough loaf your favourite client baked is sitting in the fridge (You are a star Nikki Deiner), you're no longer making a food decision. You're watching a worn out rational brain lose a fight it was never really equipped to win at that point in the day. It's not weakness. It's just how our brains work.

The implication is important: if the problem isn't willpower, the solution isn't more willpower.

Before we proceed, I just want to make it clear that this is in no way me telling you that you CANNOT have a snack. I am not one of those guys that puts food in “Good” and “Bad” categories. 

Snacking however does matter to those who are trying to control and account for the calories and macros. The French fry here and there, the square of chocolate. Licking peanut butter off the spoon etc. 

Ok.

LET’S GO!

The WORST strategy: Just try harder

Most people's approach to snacking is trying to suppress the urge every single time it arises. We call this habit inhibition.

This fails for one simple reason: it requires your rational brain to win the same fight, over and over, indefinitely, including on the days when you're at your most depleted. 

You may win most of them. But you only need to lose a few for the damage to add up. It’s a really slippery slope. The all or nothing mentality (As mentioned in a previous article) makes it even worse!

Research following people through their daily self-control battles found something striking: what determined whether people caved to temptation wasn't how strong their willpower was — it was how often they were exposed to temptation in the first place. The people who were best at self-control weren't fighting urges more successfully. They were engineering their lives so fewer urges arose.

Here’s the gameplan

Step 1: Remove the temptation entirely

The simplest and most effective intervention available to you costs nothing and requires zero willpower: don't have it in front of you.

People eat nearly twice as much chocolate when it was within arm's reach compared to two metres away. They eat significantly more from an open bowl than a closed opaque one. The food didn't change. The people didn't change. The distance changed. Visibility changed. That was enough.

If the snacks are on your desk, on the kitchen counter, or visible when you open the fridge, you will eat them — not because you're undisciplined, but because that's how every human brain responds to food proximity. The solution isn't to get better at resisting. It's to stop putting temptation in your path in the first place. 

Clear your environment of the foods that derail you. Not just hide them - remove them. What isn't there can't be eaten.

But here’s a common problem - Ever since Covid, accessibility to food and snacks got way easier with food delivery. So how? Read on..

Step 2: Swap, don't stop

The next approach is substitution. If access to snacks is too easy, substitute it with something else. This applies also if you are living with other people. It would be unreasonable to expect the rest of the household to follow your eating habits. They can have the chocolate; You “can’t”. So we substitute the “forbidden snack” with something else.

“The best way to get over someone is to get under someone else” – Substitute the snack with something else.

There’s a clear reason here why I’m not a relationship counsellor or psychotherapist. Psycho? Maybe. Therapist? No

Anyway…

Most people get their “anti-snacking” strategy wrong - Instead of steering the craving, they are fighting it. 

Telling yourself to "stop snacking" means relying on habit inhibition every single time the urge arises. Swapping the snack for a better option means redirecting the same impulse toward something that doesn't blow your macros. Your brain wants stimulation, something to do with your mouth, a small hit of pleasure. It doesn't actually need it to come from a bag of O’Lay’s.

Stock your environment exclusively with low-damage alternatives. Sparkling water, diet sodas, sugar-free gum, and other low-calorie snacks. When the urge hits, you're not fighting it — you're just steering it somewhere “cheaper”, (also explained in a previous article) somewhere where it won’t have a chance to de-rail your plans. The craving gets satisfied; the calories don't accumulate.

Step 3: Know your cues

Snacking doesn't appear out of nowhere. It's triggered. Every time you've snacked off-plan, something preceded it - a specific time of day, a particular location, a mood, a situation. Boredom at your desk at 3pm. Stress after a difficult meeting. The moment you sit down on the sofa after dinner. These are cues, and they're remarkably consistent.

Mine is when I’m watching TV. Window blinds down, air conditioning on, recliner sofa, fluffy blanket, remote control and then 

“Boom!” Chicken wings and spicy Thai food from Grab Delivery. It’s almost always the same pattern.

Once you know your cues, you have two options (As mentioned above)You can try to remove the cue itself - don't sit at your desk at 3pm without anything to do if you know that leads you to the office pantry to grab cake. As mentioned in Step 1.

Or you can build a deliberate substitute response for when the cue appears. When the 3pm slump hits, you make a black coffee, you reach for sparkling water. The trigger is identical, the reward is similar enough that the brain accepts it, but the middle part - the behaviour - has changed. As mentioned in Step 2.

The crucial point with Step 2 is that the reward has to stay. That's what makes the substitution stick. You're not removing pleasure from the thought loop — you're just changing how you get it. Try to remove the reward entirely and you're back to habit inhibition, which is just willpower with extra steps. Keep the reward, swap the behaviour, and the loop gradually rewires itself through repetition until the new behaviour becomes the automatic response to the cue.

This is called habit substitution, and it is substantially more effective than trying to simply discontinue a habit. Habits don't disappear — they get replaced. The brain’s pathway that connects the cue to the behaviour weakens when you consistently route the cue toward a different outcome.

So you might be thinking, what do I personally do in my TV situation? 

Step 2, when I am tracking my macros. 

Otherwise not even a herd of wild horses can separate me from my Thai food. “Ah Roi Mak Mak Krub!”

Step 4: Write yourself a plan

Motivation-based approaches - telling yourself you're going to do better, trying harder, feeling bad about it - are among the least effective strategies studied. What works dramatically better is an implementation intention: a specific, pre-made plan in if-then format. (We touched on this a bit in a previous article, but worth a re-mention)

Not:"I'm going to try to not snack this week."

But:"When I feel like snacking after lunch, I will grab a diet soda (NO it does not give you cancer!) and maybe take a 5min walk"

OR

“When I feel like blowing cash on food delivery, I will send a couple of coffees to my friends at 123 Devonshire Road instead” 

Black. No Sugar. Thanks.

The if-then format plugs directly into the brain's association wiring - the same system that makes habits automatic. By pre-deciding your response to the cue, you take the decision out of the hands of your depleted 3pm brain and hand it to your clear-headed brain instead. Implementation intentions are way more effective than motivation-based approaches for exactly this reason.

Write yours down. Be specific about the cue, the timing, and the substitute behaviour.

Step 5: Take more breaks

This might sound counterintuitive, but the logic is solid. Snacking spikes when mental fatigue accumulates. If you're grinding through hours of focused work and then suddenly find yourself eating something you had no intention of touching, your brain crossed a depletion threshold and went looking for pleasure. The snack was never really about food - it was self-medication for a tired mind.

Short, genuine breaks interrupt that accumulation before it reaches the danger zone. A ten-minute walk, a cold shower, a brief bout of exercise, even saying a quick prayer to thank your God for all that you have – Like an abundance of food, so much that it’s become a problem! - these reset your mental state and remove the emotional pressure that drives comfort eating. Athletes who sustain high output over long periods take more breaks, not fewer. The break isn't a reward for finishing. It's part of the strategy.

Step 6: Fix your meals

If genuine hunger is contributing — not mental fatigue, but actual physical hunger between meals — the fix is in what’s causing it and not in the snacking moment.

So rather than asking "how do I resist the 3pm hunger," the better question is "why am I hungry at 3pm?" — and the answer almost always lies in what you ate before.

Most people try to solve between-meal hunger by managing the snacking itself: resisting it, substituting it, planning for it. But if you're genuinelyphysically hungry two hours after a meal, that's a signal your meal didn't do its job. No amount of sparkling water and willpower fixes a meal that was too low in protein, too low in fibre, or too low in volume to create real satiety.Which brings me to my next point. Protein(again) and fibre.

Two nutrients drive satiety more than anything else: protein and fibre. Protein triggers the strongest hormonal fullness response and keeps you satisfied longest; most people are under-consuming it relative to their body's actual needs. Fibre adds bulk, slows digestion, and keeps gastric stretch receptors satisfied for longer. A meal built around both — a substantial protein source, plenty of vegetables, and adequate volume — creates genuine satiety that holds through the afternoon without needing top-ups.

If you're hungry an hour after lunch, the lunch wasn't built right. Fix that before adding any more complexity to your plan.

As for volume - The “cleaner” the food, the more volume you get. A plate of vegetables and lean meat will fill you up longer than a chocolate bar when the calories are equated. Make sense?

The Bottom Line

Snacking isn't a discipline problem. It's an environment problem, a fatigue problem, and a meal structure problem. Your brain is doing exactly what it's designed to do - seeking pleasure when it's depleted, responding to visible food, building habits from repeated behaviour. Fighting that with willpower alone is a losing battle.

Change the environment. 

Substitute the behaviour. 

Know your Cues

Write the plan. 

Take the breaks. 

Build the meals.

Do these five things and the willpower question mostly stops mattering.
