π What is TDEE and Why It Matters
TDEE (Total Daily Energy Expenditure) is the total of all calories you burn in a day. It includes your basal metabolic rate (BMR), activity expenditure, the thermic effect of food (TEF), and non-exercise activity thermogenesis (NEAT). To lose weight you eat below your TDEE; to gain weight you eat above it. Knowing your TDEE accurately enables effective meal planning and weight management so you can reach your goal weight healthily without yo-yo dieting. Because TDEE varies greatly by age, gender, weight, height, and activity level, using a TDEE calculator to set your own precise calorie baseline is important.
