Your BMI of 54.7 puts you in the Obese Class III category for someone 5'0".
To reach the upper boundary of the healthy range (127 lbs), you would need to lose approximately 153 lbs. A sustainable rate is 0.5 to 1 lb per week, which means roughly 204 weeks at a moderate calorie deficit.
Keep in mind that BMI does not account for muscle mass. Two people at 5'0" and 280 lbs can have very different body compositions. Body fat percentage is a more precise indicator of health risk.
You would need to lose approximately 153 lbs to reach the high end of the healthy range. The healthy BMI range (18.5 to 24.9) corresponds to 95 to 127 lbs for someone 5'0". A sustainable rate of weight loss is 0.5 to 1 lb per week through a calorie deficit of 250 to 500 calories per day.
BMI is a useful screening tool but has real limitations. It does not distinguish between muscle and fat, so muscular athletes often show elevated BMI despite low body fat. It also does not account for where fat is stored. Waist-to-height ratio and body fat percentage are more precise measures. Use BMI as a starting point, not a definitive health verdict.
For someone 5'0", the healthy weight range based on BMI is 95 to 127 lbs. At 95 lbs, BMI is 18.5 (lower boundary of healthy). At 127 lbs, BMI is 24.9 (upper boundary of healthy). Below 95 lbs is underweight; above 127 lbs is overweight.
BMI only uses height and weight. Body fat percentage measures actual fat tissue as a proportion of total weight, making it more precise for body composition assessment. Two people with the same BMI of 54.7 can have very different body fat percentages depending on muscle mass. Athletes often have BMI values above 25 while maintaining low body fat. Use body fat percentage to set specific fitness goals.
