What Is BMI?
BMI (Body Mass Index) is a numerical value calculated from your weight and height. It categorizes you into:
- Underweight (BMI < 18.5)
- Normal weight (18.5–24.9)
- Overweight (25–29.9)
- Obese (≥ 30)
Formula:BMI=Weight (kg)Height (m)2BMI=Height (m)2Weight (kg)
(For pounds/inches: [Weight (lbs) ÷ (Height (in))²] × 703)

Why BMI Matters
- Health Risk Indicator:
- Higher BMI correlates with risks like heart disease, diabetes, and hypertension.
- Low BMI may signal malnutrition or osteoporosis.
- Fitness Benchmark:
- Athletes may have high BMI due to muscle mass (not fat).
- Insurance/Medical Use:
- Used by doctors to screen for weight-related conditions.
Limitations of BMI
BMI isn’t perfect. It doesn’t account for:
- Muscle vs. fat distribution (e.g., a bodybuilder may be “obese” on BMI).
- Age, sex, or ethnicity (Asian populations may face higher risks at lower BMIs).
- Waist circumference (a better marker for visceral fat).
📊 Pro Tip: Pair BMI with body fat percentage measurements for accuracy.
How to Improve Your BMI
If Your BMI Is Too High
- Nutrition:
- Eat whole foods (vegetables, lean proteins).
- Reduce processed sugars and saturated fats.
- Exercise:
- Mix cardio (walking, cycling) and strength training.
- Sleep & Stress:
- Poor sleep spikes cortisol, increasing fat storage.
If Your BMI Is Too Low
- Caloric Surplus:
- Add healthy fats (avocados, nuts) and protein.
- Strength Training:
- Build muscle mass with resistance exercises.

Is BMI accurate for athletes?
No—use body fat % instead (e.g., DEXA scan).
What’s a healthy BMI for seniors?
25–27 may be better (some fat protects against osteoporosis).
How often should I check my BMI?
Every 3–6 months if making lifestyle changes.
