What is TDEE?
TDEE (Total Daily Energy Expenditure) is a method used alongside the BMR to calculate the amount of calories your body needs to function in a day based on your activity levels. These levels are grouped as follows:
How are the weight projections calculated?
Each week, depending on your planned caloric intake and your activity level, you can lose, gain, or maintain your weight. If your TDEE is greater than your daily intake, you will lose weight. If you consume more than you expend, you'll gain it. Your BMR changes as you lose or gain weight, so I account for this and recalculate it each week based on the weight for that week. The table shows your expected weight for 25 weeks.
