Inspired by The Hacker's Diet I got my estimated daily totals from How Many Calories Should You Eat Per Day to Lose Weight? and I used Calories to Kilojoules (kJ) conversion for conversions.
Estimated daily calories
|1||To maintain weight||2,513||10,514|
|2||To lose weight||2,010||8,409|
|3||To lose weight fast||1,508||6,309|
If, over a period of time, the calories in the food you eat exceed the calories you burn by 3500, you'll put on about a pound. Conversely, if you reduce your food intake so that you burn 3500 calories more than you eat, you'll lose about a pound.
- 3,500 cal * 4.184 = 14,644 kJ
- 1 pound = 0.4535924 kg; 1 kg = 2.204623 lbs
- 14,644 * 2.204623 = 32,285 kJ to lose 1 kg
