Tips to Maintain a Healthy BMI
Maintaining a healthy BMI involves consistent habits. Here are a few tips:
- Eat balanced meals with plenty of vegetables, lean protein, and whole grains.
- Stay physically active – aim for 150+ minutes of moderate exercise weekly.
- Sleep well – 7–9 hours nightly is key to weight control and hormonal health.
- Hydrate – drink 8–10 glasses of water per day.
- Avoid crash diets – they lower your BMR and increase fat storage long-term.
- Track progress – recheck your BMI monthly for gradual improvements.
Limitations of BMI for Women
While BMI is a useful screening tool, it doesn’t measure:
- Muscle mass
- Water retention
- Bone density
- Hormonal fluctuations (e.g., during menstruation, pregnancy)
Therefore, it’s best used alongside other metrics like waist circumference, body composition scans, and medical evaluations.
