How long does it *really* take to lose 15 pounds? “The safest and most sustainable timeline to lose about 15 pounds would be about two to four months,” says Jonathan Valdez, RDN, towner of Genki Nutrition and spokesperson for New York State Academy of Nutrition and Dietetics.
Although everyone's body is different, in general people can expect to lose one to two pounds a week if they are doing so in a sustainable manner. "Over the course of two months or eight weeks, a healthy weight-loss goal is eight to 16 pounds," White said.
Can You Really Lose 15 Pounds In A Month? Yes, it is possible for you to lose 15 pounds a month. However, this would only be done in the unhealthy way of eating on a very-low-calorie-diet. Such diets are not recommended to people unless your doctor advises otherwise.
On average, a 15 to 20-pound loss (approximately 2 to 5 percent of your starting body weight) is enough to notice "significant changes in your body," he said. You can start seeing differences in yourself as early as two weeks with rapid weight loss.
When you lose a lot of weight, about a quarter of weight loss comes from muscle if you don't include a strength-training component to your workout routine. This helps explain why those last few pounds are so hard to lose. Your metabolism has slowed down and, therefore, you're burning fewer calories at rest.
The truth of the matter is that one may be able to shed 15 pounds in 30 days. That being said, just because it is possible does not mean it is healthy, sustainable, or that the weight loss is fat. Experts advocate for weight watchers to strive to lose between one to two pounds weekly (15).
Here is the math: 1 pound of fat = 3500 calories 3500 calories x 15 pounds = 52,500 calories (total caloric deficit to lose 15 pounds) 52,500 / 30 days = 1750 calorie deficit per day.
The first stage of weight loss is when you tend to lose the most weight and begin to notice changes in your appearance and how your clothes fit. It usually happens within the first 4–6 weeks ( 1 ). Most of the weight loss in this stage comes from carb stores, protein, and water — and to a lesser extent, body fat.
On average, a person can lose anywhere from 4 to 8 pounds in 30 days. This is in line with the CDC guidelines that suggest that a gradual and steady loss of 1 to 2 pounds a week is what is best and sustainable for long-term weight loss (11).
During an interview with Vogue, Kardashian explained, “It was this or nothing. [In the weeks leading up to the Met Gala], I would wear a sauna suit twice a day, run on the treadmill, completely cut out all sugar and all carbs, and just eat the cleanest veggies and protein. I didn't starve myself, but I was so strict.”
The CDC state that a person can safely and effectively lose about 1–2 lb a week. Based on those numbers, in a month, a person could safely lose 4–8 lb.
In terms of how your body looks, “it usually takes 4 weeks for your friends to notice weight loss, and 6–8 weeks for you to notice,” says Ramsey Bergeron, a certified personal trainer. “Your friends who don't see you every day are much more likely to see a change than someone you're around all the time,” he adds.
The first place men typically lose weight is the belly, while women tend to lose weight all over, but hold onto weight in their thighs and hips, Dr. Block explains.
“Women and men of average height need to gain or lose about three and a half and four kilograms, or about eight and nine pounds, respectively, for anyone to see it in their face,” said Nicholas Rule, associate professor in the Faculty of Arts & Science and Canada Research Chair in Social Perception and Cognition.
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. But putting off buying new clothes until you really need them doesn't work for everyone.
"Women and men of average height need to gain or lose about three and a half and four kilograms, or about eight and nine pounds, respectively, for anyone to see it in their face.
If you want to lose weight without jeopardizing your health, you can lose 6 to 12 pounds in 6 weeks. That is a maximum of 2 pounds each week. Not losing more than 1-2 pounds of weight in a week is suggested. There is one more benefit of losing weight gradually and steadily.
Losing 15 pounds in 3 weeks is going to require some serious dedication and calorie-cutting, but don't worry—it is possible!
A safe, healthy, and realistic goal is to lose 0.5-to-1% of your body weight per week, which is around 1-to-2 pounds of weight loss per week for most people. In other words, you can expect to lose 12-to-24 pounds in a 3-month period.
Going by this, it would mean that you would target losing 4 to 8 pounds monthly (1 pound x 4 weeks) or (2 pounds x 4 weeks). A more realistic goal would be shedding 20 or 40 pounds (4 pounds x 5) or (8 pounds x 5) within five months.
You can expect to lose 4-16lbs in 60 days. This equals a rate of 0.5-2lbs per week, which is a realistic and sustainable approach for most people. Losing weight at this rate can ensure that you don't lose too much muscle mass, and you won't have to drop your daily calorie intake to dangerously low levels.
