The question no calorie app asks you

Unpopular opinion: calorie counting isn't the problem. Calorie apps are.

I've been using them since 2010. I've tried the big ones, the small ones, the ones that promise to change everything. Every single one asks you the same question:

“What did you eat?”

And nobody — not one of them, in 15 years — seems to ask the more useful one:

“What should you eat next?”

This is what I want to talk about. Because once you see it, it's quite hard to unsee. And it explains, I think, why so many of us fail at tracking despite it being theoretically one of the simplest behaviour changes on earth.

The lopsided nature of every tracker

Think about what a calorie app actually does. You finish a meal, you open the app, you search for the thing, you tap a portion size, you add it to your day. Now there's a number on the screen. Great. Now what?

That “now what” is the entire game. And it's the bit the app doesn't help you with.

You're left to eyeball the remaining numbers and figure out, in your head, what your next meal should be. Given that you now have — let's see — 847 calories, 67g of protein, 82g of carbs and 24g of fat left for the day. At 3pm. With two more meals to go. And dinner is in four hours. And the kids want pasta. And you've got nothing in the fridge.

Good luck. Try to solve that one on the drive home.

Why the backwards-facing question doesn't actually help you

Here's the steelman case for “what did you eat?” — and I do want to be fair to it, because it isn't completely useless.

Logging food does two useful things. It makes you aware of what you're consuming (which helps awareness-based eaters), and it builds a data record you can look back on over weeks and months. Both of those are fine.

But here's the catch: neither of those things helps you hit your target today.

Awareness is a lagging indicator. By the time you've logged the thing, you've eaten the thing. It's too late. Yes, it'll influence tomorrow's choices a bit, but you've missed the chance to course-correct within this day. And the long-term trend data is nice, but you don't plan tomorrow's dinner from last month's data. You plan it from where you are right now.

So the information you most need at any given point — what to eat in the next four hours to hit today's target — is the exact information no tracker gives you.

The moment I realised

I was standing in the kitchen on a Wednesday evening. I'd logged lunch. I'd logged a snack. The app was showing me I had 680 calories and 78g of protein left for the day.

Great. Now what the hell was I supposed to do with that?

I stood there for about four minutes, opening the fridge, closing the fridge, opening the cupboards, trying to mentally calculate which combination of things would land me somewhere close to target without being revolting.

And the app sat there, patient, showing me numbers. Useful numbers! Correct numbers! Utterly unhelpful numbers!

That was the moment. The app knew what I'd eaten. The app knew what I was supposed to eat. The app absolutely should have been able to tell me what to have for dinner. And it was asking me instead.

Why everyone else seems to be fine with it

I've thought about this a lot. If “what should I eat next?” is such an obvious question, why hasn't anyone built a tracker around it?

I think there are three reasons, and I'll be fair about all of them.

1. Because it's hard

Giving a good answer to “what should I eat?” requires knowing your remaining macros (easy), but also your preferences (harder), what you have in the kitchen (harder still), and what's actually feasible for you to cook right now (dinner on a weeknight is not the same as brunch on Saturday). Combining all of that into a good suggestion was, until quite recently, genuinely difficult to do well.

It's a lot easier to just build a food diary.

2. Because nutrition culture is data-obsessed

There's a cultural assumption, particularly in fitness circles, that the point of tracking is the tracking. More data, more control, better outcomes. If you just have enough numbers in front of you, the argument goes, you'll figure it out.

Which is a very flattering story to tell yourself if you're the kind of person who enjoys numbers. And a spectacularly bad story if you're a normal human trying to work out dinner.

3. Because telling people what to eat feels presumptuous

Historically, apps have been reluctant to suggest food. That feels too much like nutrition advice, which is regulated, and nobody wants to be the app that tells someone with a hidden condition to have a chicken korma.

Fair enough. But there's a difference between “based on what you've said your targets are, here's a meal that would close the gap” and “we're prescribing you a diet.” The first is logistics. The second is medicine. Most apps have conflated the two and ended up providing neither.

What changes when you ask the better question

When you flip the question — when the app leads with “here's what to eat next” instead of “what did you eat?” — quite a lot shifts.

The first thing is that the cognitive load drops off a cliff. You stop standing in the kitchen doing mental arithmetic. You look at the suggestion, you go “yes” or “no, make it quicker”, and you get on with cooking.

The second thing is that hitting targets stops being a constant willpower exercise and becomes a logistics exercise. Which is good, because most of us have finite willpower and effectively infinite logistics.

The third thing — and this is the one I didn't see coming — is that you log more, not less. Because logging stops feeling like book-keeping and starts feeling like an input to a useful thing. You log, and then something helpful happens. You're not just feeding a diary.

The broader implication

If you take this one idea seriously — that the useful question isn't “what did you eat?” but “what should you eat next?” — it reshapes a lot of things.

It means meal plans are mostly the wrong tool. Plans are rigid; days are flexible. What you need is a system that bends with you, not a plan you try to bend yourself to.

It means the long-term “streaks” and “consistency badges” apps hand out are measuring the wrong thing. The right thing to measure is whether, on any given day, the app successfully helped you hit your target. Not whether you logged diligently.

And it means the entire business of “meal prep culture” — cooking six identical Tupperwares on a Sunday so you don't have to think about it — is a workaround for a tool that's never existed. If the tool existed, you wouldn't need the Tupperware.

So, what then?

This post is called a hot take and I've done my best to deliver it. But it's not really a hot take — it's the observation that finally made me stop waiting for an existing app to solve this and have a go myself.

FeedMe is what came out of it. You log what you had, it shows you where you are, and it tells you what to eat next to hit your target. That's the whole thing. Everything else — the fasting windows, the pantry-aware recipes, the chat refinement — sits around that central flip.

I might be wrong about all of this. Maybe most people genuinely prefer doing the mental maths themselves. Maybe there's a good reason no big app has shipped this. Happy to be told so. Drop me a line and tell me I'm wrong — I read everything.

Until then, I'll be over here, asking the question I think the industry has been dodging for 15 years.
