How much weight do you need to lose? - NHS
When trying to lose weight, it's tempting to want fast results. But studies show people who lose weight too fast end up putting it back on again. The NHS weight loss plan is designed to help you lose weight at a safe rate of 0.5kg to 1kg (1lb to 2lb) per week by sticking to a daily calorie allowance of 1,900kcal for men and 1,400kcal for women.
