Constant hunger and food cravings: why they happen, and what to test

Commonly a combination of under-eating protein and fibre earlier in the day, accumulated sleep debt, and the fact that evening is when most people are unoccupied and near food. All three are addressable and none of them is a character defect.

It measures what sits underneath it and a registered doctor reads that. What follows is a clinical decision made with you, and it is not something we can describe on a public page.

This page describes physiology and behaviour, and that is the boundary it keeps. It does not offer anything that alters appetite, and it makes no claim that this service does — what a doctor may decide after seeing your results is a clinical matter, discussed with you, and not something a public page in India may go anywhere near. Hunger that does not respond to effort is worth measuring rather than out-arguing. The panel looks at what sits underneath it, and a doctor reads it.

• Appetite is signalled, not decided. Hormones from the gut and from fat tissue report on recent intake and on stored energy, and the brain integrates that with sleep, stress, habit and what is within arm's reach. Very little of that sequence is available to introspection.
• Short sleep changes the signal measurably. Controlled studies of restricted sleep report increased hunger ratings and shifted appetite hormone levels the following day. It is one of the few inputs that is both well documented and genuinely adjustable.
• Losing weight raises appetite, and it stays raised. Following weight loss, hunger signalling increases and energy expenditure falls somewhat, and both persist well beyond the period of loss. This is ordinary physiology responding to a change, not a lapse in resolve.
• The size and duration of this effect varies considerably between people, and predicting it for an individual is not currently possible.
• The Indian plate matters here specifically. Protein and fibre are the components most associated with fullness in trial data, and they are the two most commonly short in a plate built mainly from refined grain — which is a structural problem, not a discipline problem.

• We describe how hunger works. We do not describe anything that changes it, and no public page here can.

• You are experiencing binge eating, purging, or food thoughts that dominate your day. That deserves proper eating-disorder care, which is not what this is — please read the safety page.
• You want an appetite suppressant. We do not offer one and no public page in India may discuss one.
• You are pregnant or breastfeeding, where appetite changes are expected and dietary restriction is inappropriate.
• You are under eighteen. This service is for adults.

• Sleep restriction trials (controlled laboratory studies of short sleep in adults): Report increased subjective hunger and altered appetite hormone concentrations after restricted sleep.
• Satiety literature (controlled feeding studies of protein and fibre): Higher protein and fibre at a meal are associated with greater reported fullness and lower subsequent intake.
• Post-loss adaptation studies (follow-up of appetite and energy expenditure after weight loss): Find persistent increases in appetite signalling and reductions in expenditure lasting well past the loss itself.

Appetite is the system most people assume is the enemy, and the one a plan has to be built around rather than over.
