Total Daily Energy Expenditure without guesswork

TDEE in plain words

Total Daily Energy Expenditure adds up your basal metabolism, digestion and all daily activity. Knowing it prevents you from slashing calories randomly or overeating without noticing.

Main contributors

60-70 %

Basal metabolism

Energy your body needs at rest.

~10 %

Thermic effect

Cost of digesting and absorbing food.

10-30 %

Activity

From structured workouts to everyday NEAT.

Working with the calculator

  1. Provide age, sex, weight and height.
  2. Select the activity level that matches a typical week.
  3. Choose the goal: maintenance, mild deficit or controlled surplus.
  4. Apply the suggested calories and tweak only 10-15 % at a time.

Slow beats extreme

Aggressive deficits are hard to sustain and increase the risk of muscle and micronutrient losses.

Interpreting the output

Think of the number as an estimate. Stress, hormones or changes in muscle mass can shift it by a few hundred calories. Reassess every 2-3 weeks based on your actual progress.

Adjust calories around your TDEE in small increments to keep progress sustainable.

Next steps

  • Anchor meals around protein and vegetables to improve satiety.
  • Prioritise resistance training and daily steps to raise NEAT.
  • Log weight or measurements weekly to compare against the plan.
  • Adjust if you drop more than 1 % of body weight per week (deficit too large).
