Worked examples: what really happens
Here is the same 60 pound goal for two people, each eating 500 calories a day less than they burn at the start, a plan that would take 60 weeks by the 3,500 calorie rule.
How long does it take to lose 60 pounds?
A quick answer, a calculator for your own timeline, and worked examples showing why 60 pounds often takes a bit longer than the simple math suggests.
At a steady 1 pound a week, losing 60 pounds takes about 60 weeks (roughly 14 months). In practice it usually takes a little longer, because weight loss slows as you get lighter. In our worked examples it took about 64 weeks.

Day-by-day estimate using the Mifflin-St Jeor equation, re-estimated as your weight changes. Real progress varies week to week; this is not medical advice.
Projected weight by week
| Pace | Time |
|---|---|
| Gentle: 0.5 lb a week | 120 weeks (about 27.5 months) |
| Steady: 1 lb a week | 60 weeks (about 14 months) |
| Fast: 1.5 lb a week | 40 weeks (about 9 months) |
| Very fast: 2 lb a week | 30 weeks (about 7 months) |
Simple arithmetic: 60 pounds divided by the weekly pace. Real progress is usually a little slower; see the worked examples below.
| Example | 3,500 calorie rule | Recalculating every 10 lb | Never adjusting calories |
|---|---|---|---|
| A 35-year-old woman, 205 to 145 lb | 60 weeks (about 14 months) | 64 weeks (about 15 months) | 113 weeks (about 26 months) |
| A 35-year-old man, 230 to 170 lb | 60 weeks (about 14 months) | 64 weeks (about 15 months) | 111 weeks (about 25.5 months) |
Examples: a 35-year-old woman, 5 ft 5 in, lightly active; a 35-year-old man, 5 ft 10 in, lightly active. Modeled day by day with the Mifflin-St Jeor equation.
Notice the last column. Without adjusting calories along the way, the same goal takes up to 49 weeks longer. For a 60 pound goal that difference is modest, but it grows quickly with bigger goals.
Planning for a big goal
A 60 pound goal is a long project, often a year or more. It helps to break it into stages of 10 to 20 pounds, recalculate your calories at each stage, and plan short maintenance breaks if you feel worn down. With this much to lose, it is worth involving your doctor, who can check medications that may need adjusting as your weight drops and discuss whether other treatment options could help.
How to make 60 pounds stick
- Aim for a pace you could keep for twice as long as you plan to. Consistency beats a fast start.
- Keep protein high and do some strength training to hold on to muscle while you lose fat.
- Weigh yourself a few times a week and watch the average, not single days.
- Work out your maintenance calories at your goal weight before you get there. The calculator above shows it.
Questions people ask
How long does it take to lose 60 pounds?
At a steady 1 pound a week, losing 60 pounds takes about 60 weeks (roughly 14 months). In practice it usually takes a little longer, because weight loss slows as you get lighter. In our worked examples it took about 64 weeks.
Can I lose 60 pounds in a month?
Not safely for most people. 60 pounds in a month would mean losing about 14 pounds a week, well beyond the 1 to 2 pounds a week the CDC describes as gradual and steady. Plan on at least 30 weeks, and more likely 60 or longer.
How many calories should I eat to lose 60 pounds?
About 500 calories a day less than you burn is a common starting point for losing roughly a pound a week. Use the calculator above or our TDEE calculator to find your number, and recalculate every 10 pounds.
How much will I weigh after losing 60 pounds?
That depends on where you start. Enter your current weight above and the calculator fills in your goal and shows a week-by-week projection.
