What It Takes to Lose 1kg Per Week

One kilogram of body fat contains approximately 7,700 kcal of stored energy. To lose 1kg in 7 days, you must burn 7,700 more calories than you consume — a daily deficit of approximately 1,100 kcal.

For most Singaporeans with a TDEE of 1,700–2,200 kcal, this means eating 600–1,100 kcal per day — which is very restrictive. This is why 0.5kg/week (550 kcal deficit) is generally more sustainable and preserves more muscle mass.
