The calorie was defined in 1824 by Nicolas Clément as the energy to heat 1 g of water 1 °C. Food labels use kilocalories (kcal) — 1000 "physics" calories.

§01What is

Understanding the Calories for Weight Loss

The Calories for Weight Loss computes Daily calories from 2 inputs: tdee, pounds/week. Daily calorie target to reach a weight-loss goal.

§03Practical Example

Step-by-step walkthrough

Scenario

Apply the formula to a realistic set of inputs: TDEE = 2500, Pounds/week = 1.

  1. 01Start by noting the input — TDEE: 2500.
  2. 02Start by noting the input — Pounds/week: 1.
  3. 03Substitute these values into the formula: e.tdee-500 × e.lb_week
  4. 04Compute Daily calories: the calculator returns 2000.
  5. 05Cross-check the answer by opening the Derivation panel above — every line of math is shown so you can follow the computation end-to-end.

Common Calories for Weight Loss Problems

The formula gets rearranged depending on which variable you need. Here are the patterns you’ll run into in the real world — find the one that matches your problem and follow the worked steps.

01 · PATTERN

TDEE halved

tdee = 1250 (from 2500)

Keep every other input at its default and halve the tdee. See how daily calories responds.

  1. 01New TDEE: 1250
  2. 02Baseline Daily calories: 2000
  3. 03New Daily calories: 750
  4. 04Daily calories decreases by 62.5% → use this sensitivity to plan for real-world variation.
02 · PATTERN

TDEE doubled

tdee = 5000 (from 2500)

Keep every other input at its default and double the tdee. See how daily calories responds.

  1. 01New TDEE: 5000
  2. 02Baseline Daily calories: 2000
  3. 03New Daily calories: 4500
  4. 04Daily calories increases by 125% → use this sensitivity to plan for real-world variation.
03 · PATTERN

Pounds/week halved

lb_week = 0.5 (from 1)

Keep every other input at its default and halve the pounds/week. See how daily calories responds.

  1. 01New Pounds/week: 0.5
  2. 02Baseline Daily calories: 2000
  3. 03New Daily calories: 2250
  4. 04Daily calories increases by 12.5% → use this sensitivity to plan for real-world variation.
04 · PATTERN

Pounds/week doubled

lb_week = 2 (from 1)

Keep every other input at its default and double the pounds/week. See how daily calories responds.

  1. 01New Pounds/week: 2
  2. 02Baseline Daily calories: 2000
  3. 03New Daily calories: 1500
  4. 04Daily calories decreases by 25% → use this sensitivity to plan for real-world variation.
