Total Daily Energy Expenditure
The TDEE equation that we use is called the "Mifflin-St. Jeor Equation". It was developed in 1990 and has been validated by multiple studies. Mifflin-St Jeor is gaining popularity among nutrition professionals, as the most accurate way of estimating caloric needs. According to the American Dietetic Association, it's the most accurate equation for calculating actual resting energy expenditure to within 10 percent. To calculate your TDEE, as well as Calorie targets, input your current details below, making sure you choose the correct gender.

Some useful information to take away: Your TDEE can also have additional variables; for example an active job, daily movement, Non Exercise Activity Thermogenic's (NEAT for short). By consciously moving more you can increase your NEAT. Taking the stairs, walking up escalators, parking your car further away in a car park, avoid standing still. All of these things are using up additional energy compared to staying sedentary, in turn burning more calories and increasing your TDEE. However, we do not include this into your TDEE, as these variables can continuously change. In short, this is additional bonus movement, that will aid in weight loss.
Additionally, medical conditions such as autoimmune disorders, PCOS, under-active thyroid, or being on medication such as HRT, can decrease your overall TDEE. If you are someone that fits into this category, speak to a doctor to understand how this might impact you, and what changes would be beneficial for you to implement, to help you lose weight.
