Always hungry on a deficit

"I can't stand the hunger. Does that mean I can't lose weight?" No. It means the deficit is being felt, which is what deficits do — and that the way it is arranged can probably be improved.

Hunger is expected, up to a point

Eating less than you use is a signal the body notices, and some hunger, especially before meals, is part of the deal. The distinction that matters is between tolerable — you notice it, it passes, you can think about other things — and intolerable — it shapes the whole day, you eat past the plan at night, you cannot sustain it. The first is normal. The second is a design problem, and design problems have fixes.

Levers with evidence

Levers without

"Appetite-suppressing" foods and supplements — spices, teas, fibre pills, vinegar — have, at best, effects measured in tens of kilocalories and no clinical outcome behind them. Money spent there is better spent on a food scale.

When hunger is a sign of something else

If the deficit is very large — targets far below the floors described in the pace step — hunger is the correct response and the target is wrong. And if hunger comes with a history of restriction and bingeing, with fear of food, or with eating that feels out of control, that is not a design problem for a website: it is a reason to talk to a doctor or a specialist in eating disorders, and no calorie target on this site applies until you have.

In the app

The menu can be adjusted in quantities — more protein, more volume — and every adjustment is checked deterministically against the day's target and floors, rather than quietly rewritten.
