Your food photos, like this breakfast with 12 g of protein, 24 g of carbs and 1.4 g of salt, your scale every morning, and your watch’s 5.1-mile run, 7 h 10 min of sleep and 52 bpm heart rate add up to one answer on the phone: 1.1 lb of fat came off this week, and Tuesday’s 1.8 lb jump on the scale was water from Monday’s salt and carbs.

Every Sunday, see your real progress.

Case notesHow it went

  1. Feb 5

    Start. 206 lb and 26.1% body fat on the scan, after a hard year.

  2. Feb–Mar

    Tweak. He logged what he already ate and changed one thing at a time. By March he ate the same lunch most days.

  3. Apr–Jun

    Settle. Meals he looked forward to, so it stopped taking willpower. 16% by June 7: 26 lb of fat in four months.

  4. Jul–Oct

    Cascade. He trained harder, his lifts climbed, and he gained 2 lb of lean mass. 12% on October 26.

Sources: 11 BodySpec DEXA scans · MyFitnessPal food log · Strong lifting log. Leanrr, which he rebuilt that year, turned his weigh-ins and scans into a daily number for how much to eat. One person’s result. Yours depends on where you start.

The research Every witness, in detail The studies behind each one, and how one catches another
The research · Leanrr

How it knows

No witness tells the whole truth alone. Checked against each other, they show how much fat came off.

Witnesses 1 and 2Your photos and your scale

The two witnesses you give Leanrr every day. Each one lies in its own way.

Witness 1 your food photos

≈ 400 cal

A photo can miss the cooking oil: our founder’s avocado scramble looked like 400 calories and was about 830.

But it knows what you ate, including the carbs and salt that make your scale jump overnight.

NIH researchers ran 102 weighed meals through four popular photo calorie apps. The apps came in 250 to 345 calories low per meal on average, most of it missed fat. NUTRITION 2026, preliminary.

Witness 2 your scale

+2 lb

Your scale bounces with water and salt: one salty meal can add 2 lb overnight.

But two weeks of mornings show what your photos missed.

Fat moves a fraction of a pound a day, so one morning can’t tell you whether yesterday worked.

Cross-checkTogether, they catch each other

Your photos explain the bounce: that 2 lb jump was water from salt and carbs, not fat.

Your scale’s trend shows what the photos missed. Here they say you’re 500 calories a day under, but the trend says 100: about 400 calories a day never made it into the photos.

Together · 14 mornings
Your scale’s trend · −0.2 lb a weekYour photos say · −1.0 lb a week

Sunday says “fat” only when both agree, and “Not sure yet” until they do.

Witnesses 3 to 6Your watch and your lifts add three more witnesses, and a body-fat scan can add a sixth

Witness 3 your workouts

650 cal

Your watch guesses what a workout burned, and none of seven wrist devices came within 20% of the real burn.

Together, your food and your scale show how far off your watch runs. If you’re losing fast without lifting, your coach suggests a strength session.

In a Stanford study (2017), 60 people wore seven devices while a lab measured what they really burned.

Witness 4 your sleep

5½ h

Sleep changes what comes off: on the same diet, people in bed 5½ hours lost less than half as much fat, and more lean mass.

Together, your Sunday answer shows your nights beside your food and your mornings, and marks the nights your heart rate before sleep ran above your usual.

In a study in Annals of Internal Medicine (2010), 10 dieters spent two weeks each at 8½ and 5½ hours in bed.

Witness 5 your lifts

+10 lb

Your lifts read your muscle between scans, but in a calorie deficit, strength can keep climbing while muscle shrinks.

Together, your mornings show when you’re losing fast enough to cost muscle, even while your lifts climb.

In a 2022 meta-analysis of randomized trials, people who lifted in a calorie deficit got about as strong as people who didn’t diet, but gained less lean mass. Your coach estimates your max from one hard set, so you never lift a true max.

Witness 6 a body-fat scan

24%

A scan sees fat and muscle precisely, but only on one morning, a few times a year.

Together, your latest scan sets your body-fat %, and your mornings carry it forward to the next one.

Add a DEXA or Bod Pod scan in the app. You don’t need one to start.

The coach

No meal plan. One small change at a time.

It’s how Philipp got lean: he tweaked his meals until he looked forward to them. Your coach does that with you. It picks each change from your own week, and you try it or skip it.

  1. Week 1
    Your coach noticed · your food photos

    Your matcha latte with soy milk shows up most: 7 of the last 28 days.

    One changeTry a small. It’s the same drink, about 70 calories lighter each time.

    Tried it
    Kept

  2. Week 3
    Your coach noticed · your watch

    On nights you eat after 9 pm, you sleep about 40 minutes less, and your heart rate before sleep runs 6 bpm above your usual.

    One changeTry finishing dinner by 8 pm on weeknights. On longer nights, more of what you lose is fat.

    Not this week
    Skipped

  3. Week 6 · Now
    Your coach noticed · your food photos

    A doughnut and cocoa show up most mornings: 5 of the last 7.

    One changeTry 3 eggs instead of a doughnut and cocoa to reach your goal weight 27 days earlier.

What you do

Two things you do. Your coach does the rest.

I.

Point at your food

Your usual foods are one tap. Nutrition labels and barcodes count exactly; a photo is marked ≈.

II.

Step on your scale

The morning weigh-in is waiting when you wake. Your scale sends it; you don’t type a thing.

Your coach
  • Checks your food photos, scale and watch against each other.
  • Finds one change at a time for you to try or skip.
  • Shows your real progress every Sunday.
Price

Every day, for about the price of two sessions with a trainer.

Questions

I don’t have time for this.

That’s who it’s for. A photo of your food takes a few seconds, your scale sends the weigh-in, and Sunday’s answer takes a minute to read. Your coach does the math and the reading.

Won’t I end up skinny fat?

Not at Leanrr’s pace. Cutting too fast is what costs muscle, and the fastest safe pace takes at most 5% of your fat mass a week, slowing as you get leaner. Philipp kept lifting and gained 2 lb of lean mass while he lost 33 lb of fat.

What if it isn’t for me?

Monthly comes with a 30-day money-back guarantee, no questions asked.

How do you estimate how fast I’ll lose it?

From your weight and body fat today and how lean you want to be. The fastest safe pace loses at most 5% of your fat mass a week, so the pace slows as you get leaner and your muscle is kept. Your coach checks the estimate against your real weigh-ins every Sunday.

When will I know it’s working?

Your coach starts on day one. By day 30 you’ll see which way you’re heading. Weigh in most mornings, and your first sure answer usually comes in 5 to 8 weeks.

Will it tell me what to eat?

No meal plan. It starts from what you already eat and suggests one swap at a time on your own foods.

Photos aren’t exact, are they?

No photo is. Leanrr counts nutrition labels and barcodes exactly, marks photo estimates with ≈ and learns your usual amounts.

I won’t weigh in every day.

You don’t need to. Weigh in 4 or more mornings a week. Skip a whole week and the count starts over.

What do I need?

An iPhone and a bathroom scale. A smart scale and an Apple Watch make the coach sharper. Not on Android yet.

Who is it not for?

Anyone with a history of an eating disorder, and anyone under 18.

Is my data sold?

No, and we never will. Our website uses Google Analytics and Meta and Reddit ad pixels to measure our ads; our privacy policy lists them. The iPhone app has no ad or analytics trackers. Your food photos go to Google’s AI only to work out what’s in them.

A note from Philipp

You’re good at your job. That usually means long days, stress and dinner at your desk, and the weight creeps on. You don’t have time to learn nutrition or follow a meal plan.

That was me by the end of 2022, two years into a demanding role. In 2023 I went from 26% to 12% body fat, 33 lb of fat gone and my muscle kept, most of it in the first four months, without a meal plan. I kept tweaking what I ate, one thing at a time, until I had three meals I loved and ate almost every day. I looked forward to every one, and that made me want to lift harder.

I did it with Leanrr, which I rebuilt for myself that year: it turned my weigh-ins and body-fat scans into a daily number for how much to eat. Now it’s the coach that does that with you, every day.

I’d love for you to try it. If it isn’t for you, you get your money back.
