Noom is a behaviour-change programme. Its product is human coaches, CBT-based daily lessons and a community, built around daily food logging and daily weigh-ins. That is a real thing to want, and it is genuinely what Noom sells.

Fettle is not that. There are no human coaches and no behaviour-change psychology in Fettle — we should say that plainly rather than blur it. Fettle sets your calorie and macro targets, re-derives them every week from your weight trend, names the state it has put you in and shows the reasoning, then turns the resulting plan into meals and the meals into a ready-to-buy grocery checkout. It doesn’t just count. It decides.

So the question isn’t which app is better. It’s whether the thing standing between you and your goal is understanding your eating habits, or deciding and organising what to eat each week.

Side by side.

Side by side.

The core difference: how often it asks for you.

Noom’s method runs on daily input — log your food each day, weigh in each day, take the day’s lesson. That daily contact is the mechanism; it isn’t incidental to the programme.

Fettle asks for one check-in a week. Roughly two minutes: your weight, and how the week actually went. From that the Engine re-derives your targets, names the state — holding, adjusting, plateau escalation, diet break, mini-cut, protective hold — and shows you why. Logging still exists in Fettle, for the days that don’t go to plan. It just isn’t what the system runs on.

One is built around daily contact. The other is built around a weekly decision. Neither is a trick — they’re different mechanisms, and they suit different people.

Where Noom is the better choice.

If what you need is a human being who checks in on you, Noom has that and Fettle does not. If you already know roughly what to eat but keep not doing it — stress eating, evening grazing, the cycle of starting again on Monday — that is a psychology problem, and Noom is built for psychology problems. The daily lessons, the coach, the community: that is the product, and it is a serious one.

Fettle offers none of that. No coach, no lessons, no accountability, no community. If those are the things that would make the difference for you, Fettle is the wrong app and you should choose Noom.

Noom also has a medication pathway through Noom Med, its separate telehealth tier. Fettle has no medication pathway at all.

This is Fettle.

MacroFactor adapts your targets. Fettle adapts them too — then plans the meals and turns the plan into a one-tap grocery checkout.

A calorie target set in week one is wrong by week six — the body it was calculated for no longer exists. So people do everything right, stall anyway, and blame themselves. The plateau isn’t a discipline failure. It’s a tooling failure.

It decides what you eat

Fettle proposes the meals and the portions that already fit your targets, rather than leaving you to reverse-engineer a day from a calorie budget.

It adapts weekly, and says why

Every week the Engine re-derives your targets from your trend, puts you in a named state, and shows the reasoning on screen. Nothing changes silently.

It finishes the job

The plan aggregates into a grocery checkout, so the food is bought before the week starts. Planning, recipes, logging and checkout sit in one pipeline.

The short version

Noom helps you understand why you eat, with people and lessons around you, on a daily rhythm. Fettle decides what you eat, adapts it weekly from your trend, and turns the plan into a basket — with no coach and no psychology component.
