Health Tips for Maintaining a Healthy BMI
- 🍎 Eat a balanced, high-fiber diet with protein and healthy fats
- 🏃 Exercise regularly – aim for at least 150 minutes/week
- 💤 Sleep 7–9 hours daily – sleep affects metabolism
- 💧 Stay hydrated – at least 8 glasses of water a day
- 📏 Track progress every month – don’t obsess over daily changes
- 💡 Avoid crash diets – they lower your metabolism and increase fat storage
- 🧘 Manage stress – high cortisol can affect weight gain
Limitations of BMI
BMI is a helpful screening tool but has limitations:
- Doesn’t differentiate between muscle and fat
- Doesn’t account for bone density or hydration
- May misclassify athletic or muscular women
- Doesn’t account for hormonal weight fluctuations
That’s why our calculator also shows body fat %, BMR, and personalized calorie needs for a more complete picture.
