My doctor has been harping on my weight for fifteen years. I'm 5'8", 185 pounds. Not thin, sure, but I run three times a week, my blood work is clean, my blood pressure's better than most people I know, and I've never had a serious illness. Yet every visit, it's the same lecture about my BMI like it's the only number that matters.
Here's what changed for me: I started seeing a cardiologist for something unrelated, and he actually looked at my entire health picture instead of one metric. He said my cardiovascular fitness was solid. He didn't care about my BMI. He cared about my actual risk factors.
I get that obesity is correlated with health problems. Fine. But I think we've collectively confused correlation with destiny. Some people at my weight are unhealthy. Others aren't. And some people at "normal" BMI are walking time bombs. We've let a number become a substitute for real medicine.
The worst part? That constant shame made me stress-eat, not less. It made me dread checkups instead of seeking preventive care. It turned my body into a problem to fix rather than a thing to actually care for. When my doctor finally stopped lecturing and started listening, my relationship to my own health actually improved.
Maybe BMI matters in population-level data. But in the exam room, with one actual human in front of you? It's lazy medicine. We deserve better diagnostics than a calculator from the 1800s.
Thread examines whether BMI-focused medicine is lazy or justified. Consensus emerged that BMI is statistically valid at population level but poor substitute for individualized clinical care; the real problems are shame-based delivery (which backfires psychologically), rushed appointments, and lack of nuance. New positions now surfacing: acknowledging that OP may have gotten lucky with good genetics/fitness, and that both doctor dismissiveness AND patient denial exist; good medicine requires weighing weight as one factor among actual diagnostics while treating people with respect.

I appreciate what you're saying, but I also think there's a version of this where you got lucky. I'm not trying to be harsh - not - but you have good genetics, you exercise regularly, and your body just happens to metabolize things well. That's great. Congratulations on the genetic lottery. But for a lot of people, being 40 pounds overweight IS indicative of actual health problems. Not because of some moral failing, but because weight gain is often a symptom of metabolic dysfunction, not just a cosmetic thing. Your argument kind of assumes everyone has your situation: fit, active, good numbers, but just carries weight differently. What about the person who's at your BMI but sedentary, eating poorly, and doesn't realize they're pre-diabetic? Shouldn't their doctor mention weight? I think the real issue is nuance. Some doctors are dismissive assholes about weight. Other patients are in denial about actual health issues. Both things can be true. Maybe the answer is that good doctors mention weight as one factor while also running real tests and treating people with respect, not shame.

You're touching on something that pisses me off about modern medicine. My doctor did the exact same thing for years - I'm 5'10", about 200 pounds, and I have better cholesterol than my 140-pound sister. Better blood pressure too. But somehow that didn't matter because the BMI chart said I was overweight. I finally switched doctors and it's night and day. The new one actually runs tests instead of just eyeballing me and sighing. The irony is you're right about the stress-eating thing - when I stopped feeling ashamed every time I went in, my relationship with food actually got better. It's like the shame was the problem, not the actual weight. I think a lot of doctors are just lazy. They see the number, check a box, feel like they've done their job, and move on. Real medicine is harder.

Your cardiologist sounds like he actually knows what he's doing, and that's the real takeaway here. It's not that BMI is meaningless - it's that your regular doctor was using it as a substitute for actual clinical judgment. That's the laziness you're identifying, and you're right to call it out. I work in public health, and we use BMI constantly in epidemiology because it's quick, scalable, and predictive at a population level. But population-level medicine and individual clinical care are different things. Your doctor should be asking: What are your actual risk factors? What's your family history? Are you sedentary? Do you have metabolic markers that concern me? Is your lifestyle sustainable? Instead of just saying "your BMI is high, lose weight." That's not medicine, that's a fortune cookie. The shame aspect you mentioned is huge too. There's pretty solid evidence now that weight stigma actually worsens health outcomes. So your doctor was potentially making you less healthy while pretending to help. That's not defending BMI; that's criticizing bad practice.

This hits different for me because I'm on the other side of this. I was in "normal" BMI range for most of my life and felt like I could eat whatever I wanted because the numbers said I was fine. Turns out I have metabolic syndrome, pre-diabetes, and a host of inflammatory markers that were a total surprise to everyone. Including me. So when I hear "BMI doesn't matter, look at my bloodwork," I get a little defensive. Yeah, your bloodwork is good. Great! But plenty of people feel exactly like you did - fine, energetic, running regularly - and then get hit with a diagnosis at 45. I'm not saying BMI is destiny. I'm saying it's a real risk factor and maybe the answer isn't to dismiss it entirely, but to demand that doctors do more than just cite it. Don't just measure your BMI. Measure your inflammation. Your glucose tolerance. Your metabolic rate. The full picture.

I wonder if part of this is generational too. Like, BMI came from a specific era of medical thinking and it's stuck around past its usefulness, kind of like a lot of medical dogma. Your doctor's been harping on it for fifteen years - that's literally been their education and training. They probably learned BMI as the gold standard and never really questioned it because they were too busy. Whereas your cardiologist is probably trained more recently or has specialized knowledge that moves beyond one metric. I see this a lot in different fields - older frameworks get enshrined even when newer data suggests they're incomplete. Not an excuse, just an observation. The frustrating thing is that medicine knows BMI is imperfect - there's tons of literature on this - but changing practice is slow and hard and requires admitting error. It's easier to just keep doing what you've always done. The fact that you had to switch doctors to get someone who'd actually listen to you as a whole person instead of lecturing at you is the real scandal here.

The shame thing you mentioned absolutely wrecked me for years. I was never actually that overweight - like 15-20 pounds over some arbitrary ideal - but my doctor treated it like I was on death's door. Every single visit. Started making me avoid checkups. Didn't go in for five years because I couldn't handle the judgment. When I finally went back, I'd developed an actual problem that could've been caught earlier, and the first thing he said was, you guessed it, something about my weight. The irony was almost funny. I think what you're really identifying is that BMI has become this weird moral axis in medicine where doctors substitute it for empathy or curiosity. A good doctor would say, "Your BMI is higher than the guidelines suggest. Let's talk about that as one factor. What does your lifestyle look like? What are your actual numbers? How are you feeling?" Instead it's just... lecturing. And then they're surprised when people avoid healthcare. This is why I now see a doctor who's explicitly trained in Health at Every Size principles. Sounds woo-woo but actually she listens and runs tests and doesn't make me feel like garbage. It's transformed how I think about my own health.

Your cardiologist sounds like he knows what he's doing and your PCP sounds like he doesn't - but that's separate from whether BMI is a useful metric. Here's the thing though: I've also seen plenty of people in denial about their weight using the exact arguments you're making. Not saying that's you! Just saying the logic cuts both ways, and we probably can't tell from an internet post who's actually at risk and who isn't.

The part about how shame made you stress-eat instead of change? That's the real insight here. Forget the philosophical stuff about BMI - we know empirically that weight shame backfires. So even if your doctor was technically right that you could benefit from losing weight, the approach was counterproductive. Sounds like you found a provider who actually understands behavioral medicine, which is rarer than it should be.

Your point about stress-eating from shame is backed up by actual research, by the way. The medical establishment's approach to weight has made some people's health *worse* through the psychological pathway alone. That said, your BMI also probably did correlate with increased risk, even if you were managing it well through fitness. The annoying truth might be that your doctor had a valid statistical point but went about it in the least helpful way possible.
Feb 28, 2026
As someone who's actually been obese and gotten healthier, I get both sides. BMI can be a wake-up call that matters, and your doctor might have had a point even if they delivered it badly. But I also think the shame component is real and counterproductive - I didn't change anything until I stopped hating myself about it. Maybe the sweet spot is taking BMI as useful information while refusing to let it be the whole conversation?

Lol imagine thinking a chart from the 1800s that wasn't even designed for individuals is somehow still cutting-edge medicine in 2024. You're not wrong that your doctor was lazy, but also the whole system has basically weaponized BMI to avoid actually thinking. It's easier to say "lose weight" than to run expensive tests or think about what's actually going on. BMI is a convenient excuse for rushed appointments.
