About 7,700 kcal per kg (3,500 kcal per pound). A 500 kcal daily deficit is roughly 0.45 kg or 1 lb a week. Real loss slows over time as your maintenance calories drop, so treat the timeline as a best case.
Most guidelines suggest 0.5-1 kg (1-2 lb) a week. Faster loss is harder to keep off and costs more muscle.
