Good to know
Without a target date, the steady date assumes 0.5 kg a week, and the earliest date assumes the site's maximum safe pace: 1 kg a week for loss or 0.5 kg a week for gain.
With a target date, the needed pace = weight change ÷ weeks left, and the daily calorie change ≈ pace × 7,700 ÷ 7. If the date would need more than 1 kg a week of loss, it is marked too fast and the earliest safe date is shown instead.
Goals below a BMI of 18.5 for your height are not accepted. For a wedding, exam or event, starting early with a steady pace is easier to keep than a crash diet, and the weight is more likely to stay off.
Questions
Can I lose 10 kg in a month?
No, not safely. That is about 2.3 kg a week. At the 1 kg a week maximum it takes at least 10 weeks.
What is a realistic goal date?
At 0.5 kg a week: number of kg to lose × 2 weeks.
What daily calorie change does 0.5 kg a week need?
About 550 kcal a day, from eating less, moving more or both.
Why is my target date marked too fast?
It would need losing more than 1 kg a week, which this site does not recommend without medical supervision.
