A straight answer, a table for one to six months, and a calculator for your own numbers.
Last reviewed October 19, 2026
Most people can expect to lose about 4 to 8 pounds of fat in a month at a healthy pace of 1 to 2 pounds a week. The scale may show more in the first month, because early weight loss includes water.

What sets your monthly number
Three things matter most. The size of your daily calorie gap, how much you weigh to begin with, and how consistent you are. A 200 pound woman eating 500 calories a day less than she burns loses about 4 pounds of fat in her first month. A heavier person with the same gap loses about the same amount at first, but can usually afford a larger gap safely.
Per month, the numbers drift down over time. That is not failure; your body simply needs fewer calories as it gets smaller. Recalculating your target every 10 pounds keeps the pace steadier.
Why the first month often looks bigger
When you cut calories, especially carbohydrates, your body uses up stored glycogen, which is held with water. That can show up as several pounds in the first week or two. It is a real change on the scale, but not fat, and it comes back if you return to old eating habits.
A realistic monthly target
4 pounds a month (about 1 lb a week) suits most people and is easy to sustain.
6 to 8 pounds a month is reasonable if you have more to lose and can keep a larger calorie cut.
More than 8 pounds a month after the first month usually means a cut that is hard to keep up, and more of the loss may come from muscle.

Questions people ask
How much weight can you lose in a month?
At a steady 1 to 2 pounds a week, about 4 to 8 pounds of mostly fat. The first month can show a few pounds more on the scale because of water loss early on.
How much weight can you lose in 2 months?
About 8 to 16 pounds at 1 to 2 pounds a week. Most people with a moderate calorie cut land around 8 to 9 pounds.
How much weight can you lose in 3 months?
About 12 to 24 pounds at 1 to 2 pounds a week. Progress slows over time unless you lower your calories as you lose weight.
Is losing 10 pounds in a month safe?
It is faster than the 1 to 2 pounds a week the CDC describes as gradual and steady. Some people with a lot to lose see it in the first month, largely from water. As a target for most people, it means a calorie cut that is hard to sustain.
