You’re standing on the scale. The little red needle or the flickering digital digits give you a number, and immediately, your brain starts doing gymnastics. Is that good? Bad? Are you "heavy" or just "sturdy"? Most people asking how much should be my weight are actually looking for a sense of permission to feel okay in their own skin, or they’re trying to hit a target that some insurance company flyer told them was "ideal" back in 1994.
Let’s be real. That number is a liar.
It doesn't tell you how much of that weight is a dense slab of leg muscle from hiking or how much is water because you had extra soy sauce on your sushi last night. It definitely doesn't tell you if your heart is actually pumping efficiently. We’ve been obsessed with a single metric for decades, and honestly, it’s kinda ruining our relationship with our bodies.
Why the BMI is basically a broken yardstick
If you look up your weight on a standard Body Mass Index (BMI) chart, you’re using a tool invented in the 1830s by a Belgian mathematician named Lambert Adolphe Jacques Quetelet. He wasn't a doctor. He wasn't a nutritionist. He was a statistician trying to find the "average man." He literally explicitly stated that BMI should not be used to measure the health of a single individual. And yet, here we are, nearly 200 years later, using it to determine if we’re healthy.
BMI is calculated by taking your mass and dividing it by the square of your height.
$BMI = \frac{mass_{kg}}{height_{m}^2}$
It’s a simple ratio. But it’s too simple. If you take a professional rugby player or a dedicated weightlifter, their BMI will often scream "Obese." Why? Because muscle is significantly more dense than fat. Their hearts are fine, their blood pressure is perfect, but the chart says they’re failing. Conversely, you can have a "normal" BMI but have high levels of visceral fat—the stuff that wraps around your organs—which is actually quite dangerous. Doctors call this "Thin on the Outside, Fat on the Inside" (TOFI).
The factors that actually determine your "right" weight
So, if the chart is a bit of a mess, what actually matters? Your "ideal" weight is a moving target influenced by genetics, bone density, and even your ethnic background.
For instance, research published in The Lancet has shown that people of South Asian descent often face higher risks of type 2 diabetes and heart disease at lower BMIs than people of European descent. This means "healthy" isn't a universal number. It’s specific to your DNA.

Then there’s your frame size. Some people genuinely have "big bones." It sounds like a cliché or an excuse, but it’s a physiological reality. If you have a larger skeletal structure, you’re going to weigh more. Period. To find your frame size, you can wrap your thumb and index finger around your opposite wrist. If they overlap, you’ve got a small frame. If they just touch, you’re medium. If there’s a gap? You’ve got a large frame. A person with a large frame will naturally and healthily carry more weight than someone with a small frame of the exact same height.
Age changes the math
We also need to talk about getting older. The weight you carried at 22 is probably not the weight you should carry at 55. As we age, we naturally lose muscle mass (sarcopenia) and our metabolism shifts. Interestingly, some studies, including those discussed by the Journal of the American Medical Association (JAMA), suggest that carrying a little bit of "extra" weight as an older adult might actually be protective against falls and certain wasting diseases. Being slightly "overweight" by BMI standards in your 70s might actually give you a better chance of surviving a major illness than being "underweight."
Better ways to track how much should be my weight
If you’re ready to ditch the scale—or at least stop letting it ruin your morning—there are better ways to gauge where you’re at.
The Waist-to-Hip Ratio: This is a big one. Take a tape measure. Measure the smallest part of your waist and the widest part of your hips. Divide the waist number by the hip number. If the ratio is above 0.90 for men or 0.85 for women, it indicates you might be carrying too much abdominal fat, which is the kind linked to metabolic issues.
The Mirror and the Jeans Test: Honestly, how do your clothes fit? Are you breathless walking up a flight of stairs? Can you carry your groceries without feeling like you're going to collapse? Functionality beats a number every single time.
Body Composition Analysis: If you really want the data, look into a DEXA scan or a high-quality Bioelectrical Impedance Analysis (BIA) scale. These aren't perfect, but they give you a breakdown of water, bone, muscle, and fat. Knowing you’re 20% body fat is way more useful than knowing you weigh 180 pounds.
The "Set Point" Theory
Ever notice how your body seems to "want" to stay at a certain weight? You diet, you lose five pounds, and then your body fights like hell to get it back. That’s your "set point." This is the weight range your body is programmed to maintain based on your hypothalamus and hormonal signals like leptin and ghrelin. While you can shift this set point through long-term lifestyle changes, fighting it with crash diets usually just triggers a famine response, making your body hold onto fat even harder.
Forget the "Perfect" number
The obsession with a specific number often leads to "weight cycling" or yo-yo dieting. This is actually harder on your heart than just staying at a slightly higher, stable weight. When you lose weight rapidly, you lose muscle. When you gain it back—and 95% of people do—you gain back fat. Do this five times, and you’ve effectively changed your body composition for the worse, even if the scale says you’re back to where you started.
What if the answer to "how much should be my weight" isn't a number at all? What if it's a state of being? A healthy weight is one where your blood sugar is stable, your blood pressure is in the normal range, you sleep well, and you have enough energy to live your life.
Actionable steps to find your healthy range
Stop chasing a ghost. If you want to actually improve your health without losing your mind over the scale, try these shifts.
Prioritize protein and lift something heavy. Instead of focusing on "losing weight," focus on "gaining muscle." Muscle is metabolically active. It burns calories while you're sitting on the couch watching Netflix. More importantly, it keeps you mobile and strong as you age. Aim for 0.8 to 1 gram of protein per pound of your target body weight.
Watch the "Hidden" inflammation. Often, the "weight" we see on the scale is actually systemic inflammation. Processed sugars and seed oils can cause your body to hold onto water and trigger an immune response. Before you cut calories, try cutting the ultra-processed stuff for two weeks. You might find you "lose" five pounds of inflammation without even trying.
Get a full blood panel. Stop guessing. Ask your doctor for a fasted insulin test and a C-reactive protein (CRP) test. These will tell you much more about your health than the scale ever will. If your insulin is low and your CRP is normal, your current weight might be exactly where your body needs to be.
Measure your "Non-Scale Victories." Start a log. Can you do more pushups than last month? Is your resting heart rate lower? Is your skin clearer? These are the real indicators of health. The scale is just one tiny, often misleading, piece of the puzzle.
Ultimately, your weight is a biological data point, not a moral judgment. Use it as a tool, not a master. Focus on the inputs—how you move, what you eat, how you sleep—and let the output (your weight) settle where it naturally wants to be when you're taking care of yourself.
Next Steps for Your Health Journey
- Find your Waist-to-Hip Ratio today to get a better sense of your metabolic health than BMI provides.
- Schedule a blood test to check your metabolic markers (HbA1c, Fasting Insulin, and Lipid Panel) to see how your weight is actually affecting your internal health.
- Audit your movement by tracking your daily steps for one week; aim for a baseline of 7,000 to 8,000 steps to support a healthy metabolic rate regardless of your current size.
- Switch your focus from the scale to "Non-Scale Victories" like improved sleep quality or increased strength over the next 30 days.
