Cravings: the physiology and the four-move response

Every food named in this article is an example, not an instruction — one way a person might choose to meet their targets. Swap anything for foods that fit your own needs, allergies, budget and beliefs. For advice specific to you, talk to a registered dietitian or your physician.

At 9pm on day eleven you will want something specific. Not food — that thing, from that cupboard. The wanting is real, it is not a character flaw, and it responds to a procedure.

The reason a procedure works is that what feels like one experience is actually three different problems wearing the same coat. Telling them apart takes twenty seconds and changes the correct response entirely.

Three things that feel identical

A habit cue is triggered by context rather than need: the time, the sofa, the end of a work day, a particular mood. It arrives suddenly, it is specific about the food it wants, and it has no relationship to when you last ate.

True hunger builds gradually, is nonspecific — you would happily eat chicken and broccoli — and correlates with hours since your last meal. Under-eating is the third and most fixable: too little protein, too little fibre, or a calorie target you have been sitting well under for days. That produces persistent, low-grade hunger no procedure will talk you out of, and the answer is more food, not more discipline.

The distinction is not academic. A cue responds to ten minutes and a change of room; true hunger responds to a meal; a shortfall responds only to fixing the day that caused it. Apply the wrong answer and you either eat when you did not need to, or grind through something that a plate of food would have solved.

Why they get worse in week two

Several things load up at once. You are in a deficit, so the hormonal signals that drive appetite are pushed in the direction of eating more — that is normal physiology and not a sign anything has gone wrong. Sleep debt from a hard week raises appetite further. And the novelty of the plan has worn off while the results are still arriving slowly.

Knowing that the curve peaks and then eases is worth more than any single tactic. Most people find the food noise quieter by the second half of the program than it was in week two.

Two of those inputs are directly under your control this week. Sleep is one of the six daily targets for exactly this reason, and total protein is the other — both of them are appetite settings as much as they are recovery or muscle settings.

The four-move ladder

Work it in order and stop as soon as it resolves. Nothing here takes more than ten minutes, and the order matters — each step is both a response and a test that tells you what the next one should be.

  • Name it. Twenty seconds: when did I last eat, is this specific or general, what just happened. Naming it as a cue is often enough to break it
  • Move and drink. Half a litre of water, a different room, ten minutes on a timer. Urges rise and fall rather than climbing forever, and most cue-driven cravings are noticeably smaller at the end of ten minutes
  • If it is still there, eat protein and green vegetables. Thirty grams of protein and as much volume as you want. That is the playbook line and it is deliberate — this is the food that ends hunger for the fewest calories
  • If it is still there after that, it was not a craving. Eat a proper meal, inside your target, and audit the day for a protein or calorie shortfall
If you are not hungry enough for chicken and broccoli, you are not hungry. You are having an urge, and urges expire.

Fixing the pattern rather than the moment

A craving that arrives at the same time every day is a schedule problem, not a willpower problem. The 4pm collapse is nearly always a lunch that was too small or too low in protein. The 9pm cupboard raid is usually a dinner eaten at six that contained no meaningful protein.

Fix the meal before the craving and the craving stops arriving. That is a considerably better use of effort than winning the same fight thirty times. Keep a note for three days of when the urges land, and the pattern is usually obvious by the end of it.

Environment does the rest, and it beats resolve every time. The highest-yield change available is not storing the trigger food at eye level in your own kitchen — not banning it, not promising never to eat it again, simply putting it somewhere a ten-second impulse cannot reach. The same logic applies to the planned treat: something you genuinely enjoy, inside your calorie target, on a schedule you set in advance, removes most of the pressure that builds when a food becomes forbidden.

When it is more than a craving

There is a difference between wanting biscuits and losing control around food. If you are experiencing episodes of eating you cannot stop, eating in secret, distress afterwards, or food thoughts that occupy most of your day, that is not something a four-step ladder addresses.

That is worth speaking to a doctor or a registered dietitian about, and it is worth doing before day thirty rather than after.
