In an era of conflicting diet advice and unrealistic social media standards, figuring out what your body should actually weigh can be incredibly confusing. Are you supposed to look like a fitness model? Or is the "Health at Every Size" movement scientifically accurate?

The truth lies in objective medical data. A "healthy weight" is not about aesthetics; it is about minimizing your risk of chronic disease and maximizing your longevity. This guide explains how to determine your optimal weight range.

Beyond the Mirror: What Defines a Healthy Weight?

Medically speaking, a healthy weight is the weight range at which your body functions optimally, placing the least amount of stress on your cardiovascular system, joints, and metabolic hormones.

When you fall outside of this range (either underweight or overweight), your all-cause mortality risk increases significantly.

The Risks of Being Overweight:

• Increased insulin resistance (Type 2 Diabetes)
• High blood pressure and elevated cholesterol
• Increased strain on knee and hip joints (Osteoarthritis)
• Higher risk of sleep apnea

The Risks of Being Underweight:

• Compromised immune system
• Bone density loss (Osteoporosis)
• Hormonal imbalances and reproductive issues
• Chronic fatigue and anemia

How the Healthy Weight Calculator Works

Our calculator uses a combination of globally recognized medical formulas—primarily based on the World Health Organization's (WHO) Body Mass Index (BMI) guidelines—to determine your optimal target range.

A "Normal" and healthy BMI is universally accepted as being between 18.5 and 24.9.

By inputting your height, the calculator reverse-engineers the BMI formula to give you the exact kilogram or pound range that will place you squarely in this low-risk zone.

It's A Range, Not a Single Number

One of the biggest mistakes people make is obsessing over a single, specific "goal weight" (e.g., "I must weigh exactly 60kg").

Notice that our calculator gives you a range. For a person who is 5'7" (170cm), a healthy weight spans anywhere from 54kg to 72kg. This 18-kilo variance accounts for differences in:

• Bone Structure (Frame Size): Some people have naturally wider shoulders, broader hips, and thicker wrists. They will naturally sit at the higher end of the range.
• Muscle Mass: Muscle tissue is much denser than fat. If you lift weights, you can easily be at the very top of your healthy weight range while having a very low body fat percentage and a slim waist.

Waist-to-Height Ratio: The Ultimate Verification

If you want to verify that your weight is truly healthy, combine the results of this calculator with your Waist-to-Height Ratio (WHtR).

Simply take a measuring tape and measure around your belly button. Divide that number by your height.

• If the result is less than 0.5, you are in excellent metabolic health.
• If it is above 0.5, you may be carrying too much visceral (belly) fat, even if your total weight falls inside the "normal" range.

Use our calculator to find your target range, and focus on eating whole, nutritious foods and moving your body daily to reach it sustainably!
