Healthy Weight: BMI, Waist Size and Realistic Steps That Work
Learn what BMI and waist measurements mean for your health, why belly fat matters, and practical, sustainable steps to reach a healthier weight in the UAE.
Quick answer
Body mass index (BMI) compares weight with height; for adults, 18.5 to 24.9 is considered healthy, 25 to 29.9 overweight and 30 or more obesity. Waist size adds important information because fat around the middle raises the risk of type 2 diabetes and heart disease. Losing even 5 to 10% of body weight through a balanced diet, regular activity and good sleep brings real health benefits.
Excess weight is one of the biggest drivers of type 2 diabetes, high blood pressure and joint problems. The good news is that modest, steady changes make a meaningful difference.
Understanding BMI
BMI = weight (kg) ÷ height (m)²
| BMI | Category (adults) |
|---|---|
| Below 18.5 | Underweight |
| 18.5 to 24.9 | Healthy weight |
| 25 to 29.9 | Overweight |
| 30 or more | Obesity |
BMI is a useful starting point but not perfect. It doesn't distinguish muscle from fat. Some health bodies, including the WHO and NICE, note that people of South Asian, Chinese, Middle Eastern and Black African backgrounds face higher health risks at lower BMIs.
Why waist size matters
Fat stored around the middle is linked to diabetes and heart disease. As a general guide, a waist measurement of more than 94 cm (37 in) for men or 80 cm (31.5 in) for women indicates increased risk, with lower thresholds advised for some ethnic groups. A simple rule: try to keep your waist below half your height.
Realistic steps
- Aim for 5 to 10% weight loss first. It improves blood pressure, blood sugar and cholesterol.
- Cut sugary drinks, including juices and sweetened coffee.
- Fill half your plate with vegetables, and choose smaller portions of rice and bread.
- Plan for social meals and gatherings.
- Move every day. In summer, walk in malls, use stairs, or exercise early morning or evening.
- Sleep seven to nine hours. Poor sleep increases hunger.
When to see a GP
A GP can check your blood pressure, blood sugar and cholesterol, look for medical causes of weight gain such as an underactive thyroid, and discuss further options if lifestyle changes are not enough.
Frequently asked questions
Are crash diets effective?
Very low-calorie diets can cause fast early weight loss, but weight is often regained. Sustainable changes work better long term, and very restrictive diets should only be followed with medical supervision.
Can medicines help with weight loss?
Some people are eligible for weight-loss medicines. These need a medical assessment and ongoing follow-up.
