What does my BMI number actually mean?
BMI (Body Mass Index) is a screening tool that estimates whether you're at a healthy weight for your height. A BMI between 18.5 and 24.9 is considered normal weight, 25-29.9 is overweight, and 30 or higher indicates obesity. However, BMI doesn't account for muscle mass, bone density, or body composition, so athletes and very muscular people may have higher BMIs despite being healthy.
How accurate is the calorie calculator?
The calorie calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating your Basal Metabolic Rate (BMR). It then factors in your activity level to estimate total daily calorie needs. While it's a solid starting point, your actual needs may vary by 10-20% based on genetics, body composition, and metabolism. Track your results and adjust as needed.
How many calories should I eat to lose weight?
To lose weight safely, you need to eat fewer calories than you burn. A deficit of 500-750 calories per day typically leads to losing about 1-1.5 pounds per week, which is considered healthy and sustainable. Most experts recommend not going below 1,200 calories per day for women or 1,500 for men without medical supervision.
Should I focus on BMI or calorie counting?
Both tools serve different purposes. BMI gives you a quick snapshot of whether your weight is in a healthy range, while calorie counting helps you manage your weight day-to-day. For the best results, use BMI as a general guide and focus on calorie intake to reach your goals. But don't obsess over numbers—how you feel, your energy levels, and overall health matter most.
