Weight Loss Timeline Calculator

At a sustainable 1.5 lbs per week, losing 30 pounds takes about 20 weeks (roughly 4.5 months). At 1 lb per week, it takes 30 weeks (about 7 months). Going faster than 2 lbs per week typically sacrifices muscle and is harder to maintain long term.

At 0.5 kg per week, 10 kg takes 20 weeks (about 5 months). At 1 kg per week, it takes 10 weeks. The 0.5 kg pace requires roughly a 500 calorie daily deficit, while 1 kg per week needs about 1,000 calories per day below maintenance.

It is realistic for the first 4 to 8 weeks, especially for people with more weight to lose. Beyond that, the rate typically slows because your TDEE drops as you lose weight. A safer long-term average is 0.5 to 1.5 lbs per week.

Daily weight fluctuates by 1 to 4 lbs from water retention, sodium, glycogen, and hormonal cycles. Track a weekly average rather than daily readings, and expect plateaus every 4 to 8 weeks as your metabolism adapts.

Yes. Your maintenance calories (TDEE) drop as you get lighter because moving a smaller body burns fewer calories. Recalculate every 5 to 10 lbs lost to keep your daily calorie target accurate and your timeline realistic.

For most adults, 1 percent of body weight per week is the practical upper limit. A 200 lb person can safely target up to 2 lbs per week; a 150 lb person should cap at about 1.5 lbs per week. Faster rates risk muscle loss, gallstones, and rebound weight gain.
