How Much Should I Weigh According to My Height?
How Much Should I Weigh According to My Height?
"How much should I weigh according to my height?"
This is one of the most common questions I get when I assess our members. And I'm going to give you an answer that I think is much more useful than simply looking at a height-and-weight chart.
Is There a Perfect Weight for Your Height?
Let's start by telling you that back in the past insurance did not want to insure people who were overweight because of their health risk. So a clever insurance company came out with a chart where people are compared to and decided if they can be insured. This chart is called the BMI (Body Max Index) and it’s based on weight and height.
But the BMI does not tell you what your body is made of. It doesn't distinguish between muscle, fat, bone, and other tissues. And that can make a big difference.
Let Me Use Myself as an Example
I am 5’7” and I am supposed to weigh 140 pounds. I used to weigh 130 pounds and was very skinny, not healthy, but now I weigh 178 pounds. According to the BMI I am over weight and therefore, not healthy under the BMI. But that is not true.
The BMI doesn't know whether the pounds I carry are muscle or fat.
That is why I don't believe you should judge your entire health based on the BMI alone.
BMI Has a Limitation
The BMI should not be treated as a complete assessment of an individual's health. For example, two people could both be 5'7" and weigh 178 pounds.
One could have a relatively high amount of body fat and very little muscle. The other could be muscular and relatively lean. They have the same height. They have the same weight. Their BMI is the same. But their body composition is very different.
That's why, when I assess someone at Custom Body Fitness, I don't want to know only what the scale or the BMI says.
I want to know what their body is made of. Therefore, I do a body composition analysis.
Your Weight Doesn't Tell the Whole Story
This is where I want you to start thinking differently. Your health is not determined by one number on the scale. Your health is influenced by your habits
Nutrition
Physical activity
Strength and fitness
Sleep
Stress management
Alcohol and tobacco use
Relationships and social connection
Mental and emotional well-being
Medical conditions
Daily habits
Your body weight is one piece of the picture. It is not the entire picture. And this is important because someone can lose weight without necessarily becoming healthier. For example, someone could lose weight through extreme restriction while losing significant muscle and failing to build sustainable habits. The number on the scale went down. But that doesn't automatically mean their health improved.
Your Habits Matter
I often tell our members that your habits create your lifestyle.
If your daily habits include eating mostly nutritious foods, exercising regularly, getting adequate sleep, managing stress, and maintaining meaningful relationships, you are building a lifestyle that can support your health.
On the other hand, if your daily habits consistently involve overeating, being sedentary, sleeping poorly, smoking, excessive alcohol consumption, or chronic stress, those behaviors can negatively affect your health—even if the number on the scale looks "normal."
And the good news is that habits can change. You don't have to become a completely different person tomorrow. You can start today.
One healthier meal. One workout. One better night's sleep. One walk. One less sugary drink. One better decision. Then another.
What About Body Fat Percentage?
This is where body composition becomes especially useful.
Body-fat percentage tells you approximately how much of your body weight comes from fat compared with lean mass. It can provide information that BMI cannot.
However, there is no single body-fat percentage that defines perfect health for every person.
Age, sex, genetics, athletic status, measurement method, and individual circumstances all matter.
For that reason, I don't recommend obsessing over one specific body-fat number. But I have found out that healthier women are under 25% and healthier men are under 15% body fat.
However, use body composition as one useful measurement of progress, along with your strength, fitness, waist circumference, energy levels, habits, and overall well-being.
At Custom Body Fitness, body composition assessments are part of our process because we want to look at more than the scale.
You Can Be Lean and Still Have Unhealthy Habits
Being lean doesn't automatically mean you are healthy. Someone can have a relatively low body-fat percentage while engaging in unhealthy behaviors or using substances that carry significant health risks.
For example, using anabolic steroids or other performance-enhancing drugs can affect cardiovascular health, hormones, the liver, reproductive health, and other systems. Looking fit on the outside doesn't automatically tell you what is happening on the inside.
Health is more than appearance.
So, How Much Should You Weigh?
Now let's return to the original question.
"How much should I weigh according to my height?"
My answer is:
There isn't one perfect weight for your height that applies to everyone. Your height can give you a general reference range, and BMI can be one screening tool. But your weight should be considered together with your body composition, fitness, health markers, habits, age, sex, and individual circumstances.
Instead of asking only:
"How much should I weigh?"
I want you to also ask: "What is my body composition?" "How strong and fit am I?" "What are my daily habits?" "How do I feel?" "What does my overall health look like?"
Those questions tell you much more than a number on a scale alone.
The Goal Isn't Just to Weigh Less
This is one of the biggest differences between losing weight and transforming your body. If your only goal is to make the number on the scale smaller, you can accomplish that in many ways.
But if your goal is to become healthier, stronger, fitter, and more confident, you need to think beyond the scale. Build muscle. Reduce excess body fat when appropriate. Eat nutritious foods. Exercise consistently. Sleep well. Manage stress. Build meaningful relationships. Create habits you can maintain.
And give yourself time because the goal isn't simply to reach a certain number.
The goal is to become the person whose habits support the body and life you want.
Conclusion
Don't let a BMI chart tell you everything about your health. And don't let the scale become the only measurement of your progress. Use the scale as information—not as your identity.
Pay attention to your body composition. Pay attention to your strength. Pay attention to your fitness. Pay attention to your habits. And most importantly, pay attention to the direction your life is going.
If your habits are improving today, you are building a healthier future. One day of better habits may not completely transform your health. But one day becomes a week. A week becomes a month. A month becomes a year. And years of healthy habits can create a completely different life.
At Custom Body Fitness, we believe a real body transformation is about much more than losing pounds.
It's about changing the person behind the number.
