Just answer a few short questions, and you will instantly know:
1. You will know our Body-Mass Index (BMI), which helps you understand if losing weight could improve your health and risk of disease. This is a different calculation than most "online" calculators. Most online calculators will not give you a correct result if you have South Asian ancestry (specifically if you or your ancestors are ethnically from India, Pakistan, Bangladesh, Sri Lanka, and Nepal).
2. If you have overweight or obesity, you can learn how much weight you need to lose to potentially see significant improvements in health.
3. You will know your Total Daily Energy Expenditure (TDEE). This number represents the number of calories you need to eat in a day in order to maintain your current weight. It is extremely helpful to know this number while dieting. Because if you eat less than your TDEE, you will lose weight. Of course, there are more elements to creating a healthful and scientific diet, but this number gives you a "baseline" idea.
