Weight Loss Calculator — FAQs

How many calories is 1kg of fat?

~7,700 kcal. A 500/day deficit ≈ 0.45 kg/week. Real-world loss is non-linear — plateaus and water weight are normal.

Safe weekly weight loss?

0.5–1kg/week — faster loss typically sheds muscle and rebounds. Protein + resistance training protects lean mass.
