On average, every 10 lbs of weight a person loses will equate to 1 pant size smaller.
Multiple regression tells us that on average, for every 8.5 pounds lost, people dropped an inch off their waist. (And for every 1.5 kilograms lost, people dropped a centimeter off their waist.) Every 10 pounds lost was accompanied by 1.18 inches of waistline reduction.
The rule of thumb, Fernstrom says, is that losing 8 to 10 pounds translates to going down one size. Still, if you lose "up to 15 pounds, you may be OK in your old size," she says.
How quickly will you lose weight? The volunteers reduced their waist sizes by an average of 1 inch for every 4lb (1.81kg) they lost. So if you lose 1lb (0.45kg) a week you could hope to reduce your waistline by an inch after four weeks.

What should your waist measurement be? For men, a waist circumference below 94cm (37in) is 'low risk', 94–102cm (37-40in) is 'high risk' and more than 102cm (40in) is 'very high'. For women, below 80cm (31.5in) is low risk, 80–88cm (31.5-34.6in) is high risk and more than 88cm (34.6in) is very high.
For women, a 27-inch waist is roughly 9″ smaller than the average female's. And even among fit women, a 27-inch waist is on the small side. So it's a good target for overall health and fitness.
A waist circumference of greater than 40 inches for men and greater than 35 inches for women is "considered elevated and indicative of increased cardiometabolic (heart disease-related) risk," said Craig Peters, DO, an HonorHealth cardiologist.
