Most food cravings peak and pass within about 20 minutes, and they are driven far more by habit, restriction and tiredness than by a lack of willpower. A craving is a strong urge for one specific food, usually something sweet, salty or fatty, that turns up whether or not you are hungry. Hunger is the body asking for food in general. The people who learn how to control cravings are not gritting their teeth every night. They eat enough protein and fibre to stay full, they plan the foods they love instead of banning them, and they sleep. Mr PT Fitness is a private home studio at 35 McIntosh Road, Dee Why, run by Matt Reilly, a personal trainer with 10+ years' experience, and "I am fine all day, then the 9pm snacking wrecks it" is the most common nutrition problem clients bring through the door.
Why do hunger and cravings sabotage diets?
Hunger and cravings sabotage diets because most diets are built to create them. Cut food too hard, cut out whole food groups and skip meals to save calories, and you arrive at the evening hungry, tired and thinking about the exact food you banned. Willpower loses that fight most nights, and the diet gets blamed instead of the design.
The size of the deficit matters most. Eating 300 to 500 calories a day under your needs is barely noticeable after the first week. Eating 1,000 or more under is a different experience: hunger becomes the loudest thing in your day, every meal feels too small, and the first slip turns into a full evening of eating. Why crash diets fail covers what that aggressive version does over a few months.
Banning foods backfires in its own way. A food you have told yourself you can never have becomes more interesting, not less, and the first time you eat it the day feels ruined, so the eating continues. Dietitians call this the "what the hell" effect. The rule was the problem, not the biscuit.
Skipping meals finishes the job. Arriving at dinner having eaten 400 calories since breakfast guarantees a big dinner and a long night of grazing. Most of the clients who come to the Dee Why studio describing "no self-control at night" are simply under-eating until 3pm.
What is the difference between hunger and a craving?
Hunger is a general, physical need for food that builds gradually and is satisfied by almost any meal. A craving is a sudden, specific desire for one food, usually sweet, salty or fatty, that shows up with or without hunger and is often triggered by a time, a place, a mood or a sight. Telling them apart is the first skill, because they need different responses.
| Physical hunger | Craving | |
|---|---|---|
| How it starts | Builds gradually over an hour or more | Arrives suddenly, often within minutes |
| What it wants | Any food. A chicken salad sounds good | One specific food. Only the chocolate will do |
| Where you feel it | Stomach: empty, rumbling, low on energy | Head and mouth: thinking about the taste |
| Common triggers | Time since the last meal, a hard session, a small lunch | The 3pm slump, the TV going on, stress, boredom, walking past the bakery |
| After eating | Satisfied, and it stops | Often followed by guilt, or by wanting more |
| What to do | Eat a proper meal with protein and vegetables | Wait 20 minutes, then have a planned serve if you still want it |
The quickest test is the apple question. If you would happily eat an apple or a boiled egg right now, that is hunger, so eat a meal. If only the specific thing will do, that is a craving, and the 20-minute pause applies. Both are normal. Neither is a character flaw, and treating a craving like a moral failure is what turns one biscuit into the packet.

How do protein, fibre and volume keep you full?
Protein, fibre and food volume keep you full because they slow digestion, fill the stomach and stretch a meal across more hours. A meal with a palm of protein, two fists of vegetables and a serve of a fibre-rich carbohydrate will hold most people for four to five hours. The same calories as white toast and juice are gone in two.
- Protein first: protein is the most filling of the three macronutrients per calorie in feeding studies. Aim for a palm-sized serve at every meal, roughly 25 to 40g: eggs, Greek yoghurt, chicken, fish, lean mince, tofu or legumes.
- Fibre next: the Australian adequate intake is 25g a day for women and 30g for men, and most adults get closer to 20g. Oats, wholegrain bread, legumes, vegetables and fruit with the skin on close the gap without much effort.
- Volume and water: foods high in water weigh a lot for their calories, which is what the stomach notices. A big bowl of strawberries, a plate of roast vegetables or a chunky soup fills you up in a way a handful of lollies never will.
- A glass of water first: it costs nothing, and many people find that what felt like hunger at 4pm was mostly thirst and a long gap since lunch.
- Do not skip the carbohydrate: a serve of potato, rice or wholegrain bread with dinner is part of what makes the meal hold until morning. Cutting it is a common reason the 9pm cravings start.
In practice that looks like eggs on wholegrain toast for breakfast, a big salad with chicken or tuna and chickpeas for lunch, yoghurt and fruit mid-afternoon, and a protein with two fists of vegetables and some potato or rice for dinner. People eating that way rarely describe themselves as hungry, even in a deficit. Losing fat without tracking calories covers how to use hunger and fullness as your feedback instead of a number.
How do you manage cravings without banning foods?
You manage cravings without banning foods by planning them in. Decide in advance which foods you love, how often you will have them and how much, then eat that serve slowly and without guilt. A planned 40g of chocolate two or three nights a week does far less damage than a banned block that disappears on a Thursday.
- Pause for 20 minutes. Drink a glass of water, stack the dishwasher, walk to the end of the street, reply to a message. If you still want the food after 20 minutes, have it. Most of the time the urge has moved on.
- Portion before you start. Never eat from the packet. Put the serve you decided on in a bowl, put the rest away, sit down and eat it. Eating from the packet is how 40g becomes 200g without a single decision being made.
- Make the trigger harder to reach. Keep the foods that undo you out of the house, or in single-serve packs on a high shelf. Buy the small bar at the shops when you want it rather than the family block for the pantry. Environment beats willpower every time.
- Have it after a meal, not instead of one. A craving on an empty stomach takes a lot of food to settle. The same craving after a proper dinner is satisfied by a small serve.
- Write the pattern down for a week. Note the time, the place and what was happening. Most people find two or three repeat triggers, usually the drive home, the couch after dinner and Friday afternoon, and a plan for three moments is far easier than a rule for every one.
- Plan the weekend. Cravings that are managed Monday to Friday and then let loose on Saturday are the most common reason a sensible week shows nothing on the scale.
How are sleep, stress and hunger linked?
Short sleep and ongoing stress are both associated with higher hunger and more snacking, especially on sweet and salty foods. In sleep-restriction studies, people who sleep around five hours eat roughly 250 to 400 more calories the next day than when they sleep seven to eight, and they reach for energy-dense foods more often. Stress eating is a learned pattern, and it responds to the same planning as any other craving.
Sleep is the lever most people ignore. The hardest hour for cravings in most households is 9pm to 10pm, and the person on the couch is usually tired rather than hungry. Going to bed 30 minutes earlier is one of the most effective nutrition strategies there is, and it does not involve food at all. Aim for seven to nine hours, keep the phone out of the bedroom, and notice how different the next afternoon feels.
Stress eating is about the job the food is doing. The chocolate at 3pm is a break from the inbox. The chips in front of the TV are a reward for a long day. Neither is a nutrient problem, so the fix is to give the job to something else: a five-minute walk around the block, a phone call, a shower, ten minutes outside. Many clients also find a training session takes the edge off a stressful day far better than anything in the pantry.
Some hunger needs more than a plan. If hunger feels constant and out of proportion despite eating well and sleeping, or it comes with unusual thirst, unexplained weight change or fatigue, see your GP. If you feel out of control around food, swing between strict restriction and overeating, or food is causing real distress, talk to your GP, an Accredited Practising Dietitian or a psychologist. A personal trainer can help with structure and training, and should not be your only support for any of those.
If you want help putting this into a week you can live with, the nutrition plan from $120 sets your protein and fibre targets, the planned treats and a meal structure that holds through the evening, alongside 1-on-1 training from $50 a session, small group from $25 a person, or online coaching from $50 a week with monthly check-ins. It is general healthy-eating guidance within a personal trainer's scope, not a dietitian service. Clients come from Dee Why, Brookvale, Curl Curl and Collaroy.

Frequently asked questions
How do I stop cravings?
You rarely stop cravings completely, but you can shrink them. Eat enough protein and fibre at meals so you are not hungry when one hits, wait 20 minutes before acting, portion a planned serve instead of eating from the packet, and get seven or more hours of sleep. Most cravings fade within about 20 minutes.
Why am I always hungry on a diet?
Constant hunger on a diet means the deficit is too big, meals are low in protein and fibre, or you are skipping meals and arriving at dinner starving. Shrink the deficit to 300 to 500 calories a day, put a palm of protein and two fists of vegetables in every meal, and sleep more. If hunger stays, see your GP.
Are cravings a sign of deficiency?
Almost never. Craving chocolate does not mean you are low in magnesium, and craving chips does not mean you need salt. Research links cravings to habit, cues, mood, restriction and tiredness far more than to nutrient gaps. If you are craving non-food items such as ice or dirt, or you feel unwell, see your GP.
