Losing 40 pounds: what 180 to 140 lb looks like on a woman
A 5′5″ woman at 180 lb and at 140 lb, side by side. That is 22.2% of body weight, and it takes BMI from 30.0 (obese) to 23.3 (a healthy weight). Change the height, body type or model below to see the same change on someone more like you.
Each body turns once. Tap a body to pause it, tap again to resume, and tap when it stops to see all angles again.
What changes between 180 and 140 pounds
Going from 180 to 140 lb takes a 5′5″ woman from the edge of obese to the upper part of the healthy range. The change shows everywhere: the belly flattens, the waist comes back in, the arms and face slim, and clothes drop roughly two or three sizes.
At 180 lb a 5′5″ woman usually has a noticeably round belly that sits over the waistband, a thick waist and heavy arms and thighs. At 140 lb that becomes a healthy build with a little softness at the waist. 140 lb is inside the healthy range for this height (about 111 to 150 lb).
Here is the same change in 10 lb steps. The models move in steps of about 10 lb, so one step can look small; it is the run of them that adds up.
How long losing 40 pounds takes
A common rule of thumb is that eating about 500 calories a day less than you burn loses roughly a pound a week, and a pace of 1 to 2 pounds a week is what most guidance treats as sustainable. At that pace 40 lb takes about 20 to 40 weeks, roughly 5 to 10 months. Real progress is rarely a straight line: the first weeks often move faster (partly water), and plateaus are normal.
180 to 140 lb at other heights
The same 40 pounds means something different on a shorter or taller woman.

| 5′5″ | BMI 30.0, obese | BMI 23.3, a healthy weight | 111–150 lb |
| 5′7″ | BMI 28.2, overweight | BMI 21.9, a healthy weight | 118–159 lb |
| 5′9″ | BMI 26.6, overweight | BMI 20.7, a healthy weight | 125–169 lb |

The last 15 pounds are the slowest
The first 20 lb of this usually come off faster than the last 20, because a smaller body needs less food and the same habits produce less loss over time. Expect the pace to slow near 150 lb. Adding strength training at that stage helps keep the shape firm as the weight drops.
