On that half of the problem, the credit is deserved. But the other half, your expenditure, is still a population formula (Mifflin-St Jeor 1990), plus a static activity multiplier chosen once at sign-up. No real measured body fat, no metabolic adaptation. So the Lean vs Foodvisor match is not played on the photo: it is played on what the app does with the number, over 3 months of serious cutting.\n    <\/div>\n    <div class=\"phone-wrap rev\">\n      <div class=\"phone-stage\">\n        <div class=\"tap-hint mobile\" id=\"tapHintMobile\" aria-hidden=\"true\">\n          <span class=\"th-pill\"><small>Interactive demo<\/small>Tap the screen to explore the app<\/span>\n          <svg class=\"th-arrow\" viewbox=\"0 0 24 24\" fill=\"none\" aria-hidden=\"true\">\n            <path d=\"M12 4 L12 20 M5 13 L12 20 L19 13\" stroke=\"currentColor\" stroke-width=\"2.4\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\/>\n          <\/svg>\n        <\/div>\n        <div class=\"tap-hint desktop\" id=\"tapHintDesktop\" aria-hidden=\"true\">\n          <span class=\"th-pill\"><small>Interactive demo<\/small>Tap the screen<br>to explore the app<\/span>\n          <svg class=\"th-arrow\" viewbox=\"0 0 104 34\" fill=\"none\" aria-hidden=\"true\">\n            <path d=\"M4 9 C 34 1, 64 20, 94 27\" stroke=\"currentColor\" stroke-width=\"2.6\" fill=\"none\" stroke-linecap=\"round\"\/>\n            <path d=\"M86 20 L 94 27 L 84 30\" stroke=\"currentColor\" stroke-width=\"2.6\" fill=\"none\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\/>\n          <\/svg>\n        <\/div>\n        <div class=\"phone\" id=\"phone\" role=\"img\" aria-label=\"Preview of the Lean app with TDEE drill-down\">\n          <div class=\"notch\"><\/div>\n          <div class=\"phone-screen\">\n            <button class=\"phone-back\" id=\"phoneBack\" aria-label=\"Back\">&#8249;<\/button>\n            <div id=\"phoneImg\" class=\"phone-bg tab-depense\" role=\"img\" aria-label=\"Lean preview, Expenditure tab\"><\/div>\n            <div class=\"phone-zones\" id=\"phoneZones\">\n              <div class=\"z\" data-sub=\"BMR\"  style=\"top:11%;height:21%\" role=\"button\" tabindex=\"0\" aria-label=\"BMR detail\"><\/div>\n              <div class=\"z\" data-sub=\"NEAT\" style=\"top:33%;height:16%\" role=\"button\" tabindex=\"0\" aria-label=\"NEAT detail\"><\/div>\n              <div class=\"z\" data-sub=\"EAT\"  style=\"top:50%;height:16%\" role=\"button\" tabindex=\"0\" aria-label=\"EAT detail\"><\/div>\n              <div class=\"z\" data-sub=\"TEF\"  style=\"top:67%;height:16%\" role=\"button\" tabindex=\"0\" aria-label=\"TEF detail\"><\/div>\n            <\/div>\n            <div class=\"phone-navbar\" id=\"phoneNav\" aria-hidden=\"false\">\n              <button data-tab=\"bilan\"     type=\"button\" aria-label=\"Balance tab\"><\/button>\n              <button data-tab=\"kcal\"      type=\"button\" aria-label=\"Calories tab\"><\/button>\n              <button data-tab=\"depense\"   type=\"button\" aria-label=\"Expenditure tab\"><\/button>\n              <button data-tab=\"strategie\" type=\"button\" aria-label=\"Strategy tab\"><\/button>\n            <\/div>\n          <\/div>\n        <\/div>\n        <div class=\"phone-tabs\" role=\"tablist\" aria-label=\"Navigate the Lean app\">\n          <button data-tab=\"bilan\"     type=\"button\">Balance<\/button>\n          <button data-tab=\"kcal\"      type=\"button\">Calories<\/button>\n          <button data-tab=\"depense\"   type=\"button\" class=\"on\">Expenditure<\/button>\n          <button data-tab=\"strategie\" type=\"button\">Strategy<\/button>\n        <\/div>\n      <\/div>\n    <\/div>\n  <\/div>\n\n  <div class=\"snippet rev\">\n    <div class=\"lbl\">Quick answer<\/div>\n    <p>Foodvisor invented meal photo scanning in France and remains a reference for identifying what you eat: photo, food recognition, portion estimation. On the expenditure side, however, Foodvisor relies on a population formula (Mifflin-St Jeor 1990, no measured body fat) and a static activity multiplier chosen at sign-up. Lean takes the problem from the other end: recalculating every component of the TDEE (<span data-term=\"BMR\">BMR<span class=\"tt\">Basal Metabolic Rate. Energy expended at rest.

You chose it precisely for what nobody did before it: photographing your plate and letting the AI recognize the chicken, the rice, the sauce, and estimate the portions without pulling out the scale. You entered your weight, height, age and sex, and picked your activity level from a static list. The app showed you a calorie target, say 2,250 kcal to lose weight.<\/p>\n  <p>You played along. You scanned your meals, corrected the portions when the AI hesitated, kept a clean log day after day. For the first 6 weeks, it works. You lose. You are happy. Then around week 8, the scale freezes. You tighten the screw. You drop to 2,000 kcal. Again, nothing moves.<\/p>\n\n  <div class=\"statement\">\n    <div class=\"num\">&minus;10 to &minus;15&nbsp;%<\/div>\n    <div class=\"lbl\">of measured TDEE drop after 4 to 6 weeks of deficit at &minus;500 kcal\/day. Foodvisor does not detect it. Your calorie target stays frozen on your activity level from 100 days ago.<\/div>\n  <\/div>\n\n  <p>Imagine Foodvisor shows you a TDEE of 2,500 kcal. You eat 2,250 (a theoretical deficit of 250 kcal). But in reality, your <a class=\"inline\" href=\"https:\/\/lean-app.com\/en\/total-daily-energy-expenditure-tdee\/\">TDEE has dropped to 2,200&nbsp;kcal<\/a> because of metabolic adaptation. You are in a 50 kcal surplus without knowing it. No chance of continuing to lose, even with the cleanest input on the market.<\/p>\n  <p>The Foodvisor promise is clear and kept: you know what is on your plate without weighing anything. That is precious. What Foodvisor does not do is <a class=\"inline\" href=\"https:\/\/lean-app.com\/en\/comment-compter-ses-calories\/\">recompute your expenditure<\/a> as the weeks of deficit go by. And that is exactly where the promise stops, even though it is the lever that makes you lose weight.<\/p>\n<\/section>\n\n<section aria-labelledby=\"p1\" class=\"rev\">\n  <div class=\"section-label\"><span class=\"bar\"><\/span><span class=\"num\">01 &middot; Problem 1<\/span><\/div>\n  <h2 id=\"p1\">The 1990 BMR formula, without measured body fat<\/h2>\n\n  <div class=\"fig\">\n    <div class=\"fig-head\"><span class=\"l\">Figure 1 &middot; Man, 5'11\", 265 lb, 30% BF<\/span><span class=\"r\">kcal<\/span><\/div>\n    <div class=\"fig-body\"><div class=\"cv-wrap\" style=\"position:relative;width:100%;height:380px;min-height:340px\"><canvas id=\"chartBMR\" aria-label=\"BMR comparison: Mifflin-St Jeor 2500 kcal vs Lean patented proprietary model 2000 kcal, 500 kcal gap\"><\/canvas><\/div><\/div>\n    <p class=\"fig-cap\"><strong>Estimated BMR.<\/strong> Lean's patented proprietary model takes lean mass into account. Mifflin-St Jeor (a population formula, no body fat) does not. A 500 kcal gap, the equivalent of an entire lunch.<\/p>\n  <\/div>\n\n  <p>To calculate your basal metabolic rate (BMR, the energy you burn at rest), Foodvisor starts from your profile: weight, height, age, sex. That is the logic of almost every mainstream calorie tracker, inherited from population formulas like Mifflin-St Jeor. And let's be honest: it is better than the Harris-Benedict 1919 that other apps still use.<\/p>\n  <p>Mifflin-St Jeor dates from 1990 (PubMed 2305711). The sample is large (498 subjects), the indirect calorimetry methodology is serious, the formula is calibrated on a modern population: 10 \u00d7 weight (kg) + 6.25 \u00d7 height (cm) \u2212 5 \u00d7 age \u2212 161 (women) or +5 (men).<\/p>\n  <p>The problem is not the chosen formula. The problem is what no formula of this type can see: <strong>it only takes your weight into account. Not your body fat. Not your lean mass.<\/strong> No field in the Foodvisor onboarding asks for your body fat percentage, and no measurement exists in the app.<\/p>\n  <p>Yet since the 1980s, we've known that <strong>fat mass burns very little energy<\/strong> compared to the rest of the body. The liver, brain, heart, kidneys, and especially muscles are the real energy sinks. Fat mass is inert. Someone at 30% bodyfat does not burn anywhere near as much as someone at 10% bodyfat, even at identical weight.<\/p>\n  <p>Frankenfield 2013 (PubMed 23631843) compared Mifflin-St Jeor to reference indirect calorimetry across obese and non-obese cohorts. Result: 87&nbsp;% accuracy in non-obese subjects, and only <strong>75&nbsp;% in obese subjects<\/strong>. A more recent study (PMC11820646) shows that for BMIs above 35, Mifflin is off by <strong>250 to 315&nbsp;kcal per day<\/strong>. That&rsquo;s a full snack&rsquo;s worth of error in your deficit calculation.<\/p>\n  <p>500 kcal is not nothing. If the app tells you \"your BMR is 2,500\" when it is actually 2,000, everything downstream is wrong: your deficit target, your projected weekly loss, your macro split calculated as a percentage of TDEE. And no plate photo, however well recognized, corrects a wrong target.<\/p>\n\n  <div class=\"bodyscan-illust\" style=\"margin:40px auto 8px;display:flex;flex-direction:column;align-items:center;gap:14px;max-width:200px\">\n    <div class=\"mini-phone\" style=\"max-width:200px\"><div class=\"notch\"><\/div><div class=\"scr\"><img src=\"https:\/\/lean-app.com\/wp-content\/uploads\/2026\/05\/lvm-bodyscan-result.webp\" alt=\"BodyScan IA Lean : bodyfat mesur\u00e9 par photo en 5 secondes\" width=\"1179\" height=\"2556\" loading=\"lazy\" decoding=\"async\" \/><\/div><\/div>\n    <div class=\"mini-cap\">Real body fat<strong>Photo, 5 seconds<\/strong><\/div>\n  <\/div>\n\n  <div class=\"statement\">\n    <div class=\"num\">400 kcal<\/div>\n    <div class=\"lbl\">of gap between two 80 kg men, one at 10% body fat (BMR 1,900), the other at 30% (BMR 1,500).

And it&rsquo;s probably the point nobody ever explained to you.<\/p>\n  <p>Once your BMR is estimated, Foodvisor has to get to your total TDEE. The <a class=\"inline\" href=\"https:\/\/lean-app.com\/en\/total-daily-energy-expenditure-tdee\/\">TDEE is BMR plus everything else<\/a> : expenditure from steps, daily activities, sport, and digestion. Everything that isn't basal metabolism.<\/p>\n  <p>How does Foodvisor do that? Like almost every tracker: it asks you, at sign-up, to pick your activity level from a static list. In sports science these factors are called <strong>PAL levels<\/strong> (Physical Activity Level), it&rsquo;s just a multiplier applied to your BMR:<\/p>\n  <ul>\n    <li>Sedentary (PAL 1.2): desk job, little walking<\/li>\n    <li>Lightly active (PAL 1.375): occasional walking<\/li>\n    <li>Active (PAL 1.55): sports 3 to 5 times per week<\/li>\n    <li>Very active (PAL 1.725): intense sport almost daily<\/li>\n    <li>Extremely active (PAL 1.9): very intense sport or a physical job<\/li>\n  <\/ul>\n  <p>And depending on your choice, the app multiplies your BMR by the matching coefficient. That's it. That's all there is behind your daily calorie target. A box YOU ticked only once at signup. Often six months ago. Untouched since.<\/p>\n  <p>And here&rsquo;s the silent trap: this approximation is <strong>wildly imperfect<\/strong>. The difference between a day stuck on the couch watching Netflix and a day at Disneyland walking 15&nbsp;km with your kids <strong>over 1,000 kcal<\/strong>. None of the 5 boxes captures that.<\/p>\n  <p>Foodvisor does know how to track your activity: the app can count your steps and log your workouts. But that data mostly serves to display your activity, not to rebuild a full TDEE: your calorie target stays sitting on the multiplier chosen at onboarding, and sports expenditure gets added on top without NEAT and EAT being cleanly separated.<\/p>\n\n  <div class=\"fig\">\n    <div class=\"fig-head\"><span class=\"l\">Figure 2 &middot; 7 real days<\/span><span class=\"r\">kcal\/day<\/span><\/div>\n    <div class=\"fig-body\"><div class=\"cv-wrap\" style=\"position:relative;width:100%;height:380px;min-height:340px\"><canvas id=\"chartNEAT\" aria-label=\"Variabilit\u00e9 quotidienne de la d\u00e9pense calorique sur 7 jours, contre 2400 kcal fixes selon Foodvisor\"><\/canvas><\/div><\/div>\n    <p class=\"fig-cap\"><strong>Real expenditure<\/strong> measured over 7 days for a Lean user.

You might be active from Tuesday to Friday and sedentary on weekends.<\/p>\n  <p>Which box will you tick this week? The truth is that none of the 5 will be correct. So Foodvisor will give you a TDEE that is systematically decorrelated from reality.<\/p>\n  <p>The key point of this article: even with a perfect BMR formula, the static multiplier alone would break everything. You cannot estimate a <a class=\"inline\" href=\"https:\/\/lean-app.com\/en\/neat-non-exercise-activity-thermogenesis\/\">NEAT<\/a>, EAT and <a class=\"inline\" href=\"https:\/\/lean-app.com\/en\/thermic-effect-of-food-tef\/\">TEF<\/a> with a single multiplier on top of BMR.

The most subtle concept. And probably the most important.<\/p>\n  <p>When you are in a calorie deficit, your body understands it is receiving less energy than before. To protect itself, it switches into economy mode. Exactly like your iPhone's low power mode: everything keeps working, but using less energy. Your BMR drops. Your NEAT drops. Your EAT drops.<\/p>\n  <p>This is called metabolic adaptation. The scientific literature is clear and reproducible: M&uuml;ller 2015 (PubMed 26399868, Minnesota revisit), Doucet 2001 (PubMed 11430776), Nunes 2020 (PMC7484122) over 6 weeks of deficit. Here are the numbers:<\/p>\n  <ul>\n    <li>Deficit of &minus;250&nbsp;kcal per day, over 2 to 8 weeks: adaptation of <strong>5 to 10%<\/strong> (TDEE drops to 90-95&nbsp;% of the initial level)<\/li>\n    <li>Deficit of &minus;500&nbsp;kcal per day: <strong>10 to 15%<\/strong> adaptation (TDEE drops to 85-90&nbsp;%)<\/li>\n    <li>Deficit of &minus;750&nbsp;kcal per day: <strong>15 to 25%<\/strong> adaptation (TDEE drops to 75-85&nbsp;%)<\/li>\n  <\/ul>\n  <p>Lean convention: 100&nbsp;% = optimal, 90&nbsp;% = 10&nbsp;% adaptation. And since NEAT, EAT and TEF all depend directly on the BMR, almost the entire TDEE is impacted.<\/p>\n\n  <div class=\"fig\">\n    <div class=\"fig-head\"><span class=\"l\">Figure 3 &middot; 8 weeks in deficit<\/span><span class=\"r\">kcal\/day<\/span><\/div>\n    <div class=\"fig-body\"><div class=\"cv-wrap\" style=\"position:relative;width:100%;height:380px;min-height:340px\"><canvas id=\"chartAdapt\" aria-label=\"TDEE qui chute de 2500 \u00e0 2150 kcal sur 8 semaines, contre 2500 fixe selon Foodvisor\"><\/canvas><\/div><\/div>\n    <p class=\"fig-cap\"><strong>real TDEE<\/strong> over 8 weeks of deficit at &minus;500 kcal\/day. The pink curve goes down. The Foodvisor line stays flat. By week 6, you are already at maintenance. Without having changed anything.<\/p>\n  <\/div>\n\n  <p>Concretely: if you planned a 10&nbsp;% deficit on a TDEE of 2,500 (eating 2,250 per day), and your body adapts by 10&nbsp;%, your real TDEE has dropped to 2,250. You&rsquo;re at maintenance. You stop losing.<\/p>\n  <p>The trap is how insidious it is. At first, you lose weight. You&rsquo;re happy. You keep going. But week after week, the adaptation stacks. And at some point, without changing anything in your tracking, <strong>you stop losing<\/strong>.<\/p>\n  <p>95% of people go through this without understanding. They blame their willpower. They blame their \"broken metabolism\". They jump into harsher diets, which makes adaptation worse. Spiral.<\/p>\n  <p>Foodvisor never calculates metabolic adaptation. It gives you a fixed calorie target as long as you do not manually update your weight and activity level. You can scan your plates with exemplary consistency, but when you plateau after 6 weeks of cutting, the app has no idea why.<\/p>\n<\/section>\n\n<section aria-labelledby=\"solution\" class=\"rev\">\n  <div class=\"section-label\"><span class=\"bar\"><\/span><span class=\"num\">04 &middot; Lean's solution<\/span><\/div>\n  <h2 id=\"solution\">How Lean fixes each of the 3 problems<\/h2>\n  <p>Lean was not built as a Foodvisor clone.

When you eat out, at a restaurant, at friends&rsquo;, it&rsquo;s extremely practical. One photo, you close the app, you enjoy your evening.

And sticking with it is what counts.<\/p>\n  <p>The real difference is downstream: Lean displays a <strong>live TDEE that updates throughout the day<\/strong>. The more you walk, the more your expenditure rises, the more your daily calorie goal adjusts. You see your calorie balance live. It&rsquo;s more motivating than a number frozen at 8&nbsp;a.m.<\/p>\n  <p>And above all that sits the <strong>Progression Pyramid<\/strong>.

Foodvisor is the historical reference for photo recognition in France, but its calorie target rests on a population formula (Mifflin-St Jeor 1990, no measured body fat) and a static activity multiplier chosen at sign-up. These are two halves of the same problem: Foodvisor excels at what comes in, Lean at what gets burned.<\/div><\/details>\n    <details><summary>Why doesn't Foodvisor calculate BMR from real body fat?<\/summary><div class=\"ans\">Because no body fat measurement exists in the app, and population formulas only use weight, height, age and sex. Lean includes the BodyScan AI to measure your body fat from a single photo, redone every week, which enables a BMR based on your real lean mass via a patented proprietary model.<\/div><\/details>\n    <details><summary>Is Lean's photo scan as good as Foodvisor's?<\/summary><div class=\"ans\">Foodvisor keeps its head start and years of training on plate recognition, particularly portion estimation. Lean's AI photo scan identifies foods, calories and macros with comparable accuracy for daily use, and it is unlimited. On this criterion, both do the job. The real difference between the two apps plays out on the expenditure calculation.<\/div><\/details>\n    <details><summary>Foodvisor counts my steps, isn't that enough for NEAT?<\/summary><div class=\"ans\">Counting steps and integrating them into the calculation are two different things. In Foodvisor, the calorie target stays sitting on the static activity multiplier chosen at sign-up. Lean calculates NEAT directly from the real steps measured every day, with no coefficient to choose, and separates it cleanly from sports expenditure (EAT).<\/div><\/details>\n    <details><summary>Is Lean free or paid?<\/summary><div class=\"ans\">Lean is Premium, with a 7-day free trial on the annual subscription. You download, you test BodyScan AI, AI photo meal scan, TDEE recomposition, no commitment. If the tool fits your goal, you keep going. Otherwise, you cancel renewal before the trial ends.<\/div><\/details>\n    <details><summary>Can you use Lean and Foodvisor side by side?<\/summary><div class=\"ans\">Yes, especially during a transition. Some people keep Foodvisor for the coaching with a dietitian and use Lean daily for TDEE, recomposition and tracking. The double-entry effort is real: in the long run, most people choose the app that drives their calorie target, and that is precisely the ground Lean was built to be the most accurate on.<\/div><\/details>\n  <\/div>\n<\/section>\n\n<section aria-labelledby=\"conclu\" class=\"rev\">\n  <div class=\"section-label\"><span class=\"bar\"><\/span><span class=\"num\">12 &middot; Conclusion<\/span><\/div>\n  <h2 id=\"conclu\">The plate is solved. Expenditure is not.<\/h2>\n  <p>This is not Foodvisor versus Lean as a marketing match. It is input versus output, two halves of the same equation.<\/p>\n  <p>Foodvisor solved the left half: knowing what you eat, without a scale, thanks to the most seasoned photo scan on the French market. But for the right half, your expenditure, Foodvisor relies on a 1990 population formula without measured body fat, a frozen activity multiplier you tick once at sign-up, and no metabolic adaptation. The combination of the three makes any precise calorie tracking impossible beyond a few weeks of cutting. It is mathematical.<\/p>\n  <p>Lean was built for that half: BMR based on the <a class=\"inline\" href=\"https:\/\/lean-app.com\/en\/total-daily-energy-expenditure-tdee\/\">real bodyfat<\/a> (measured by BodyScan AI) via a proprietary patented model, <a class=\"inline\" href=\"https:\/\/lean-app.com\/en\/neat-non-exercise-activity-thermogenesis\/\">NEAT from real steps<\/a>, EAT per sport via MET, <a class=\"inline\" href=\"https:\/\/lean-app.com\/en\/thermic-effect-of-food-tef\/\">TEF from macros<\/a>, plus metabolic adaptation that modulates BMR week after week. Every component calculated precisely, with no magic coefficient. And the photo reflex you picked up with Foodvisor, you keep it: the AI photo scan is built in, unlimited.<\/p>\n  <p>If you tried Foodvisor seriously and did not get the results you hoped for on your cut, the problem is not you, nor the photo. The problem is the frozen TDEE under the hood. Change the engine, keep the reflex.<\/p>\n<\/section>\n\n<div class=\"get-band rev\" style=\"background:#F1E9DC;border-radius:24px;padding:48px 36px;margin:60px 0 40px;text-align:center\">\n  <div class=\"kicker\">Download<\/div>\n  <h3>Lean is available as a free download<\/h3>\n  <p>iOS and Android.
