Losing weight safely typically involves losing 1-2 pounds per week ( 1 ). This would allow you to lose 20 pounds within about 5 months at 1 pound per week or 2 1/2 months at about 2 pounds per week.
While losing 20 pounds in a month is possible, losing weight too quickly often comes with a metabolism that slows down, increased cravings, and risks that include muscle loss, gallstones, increased (or decreased) hormones, and nutritional deficiencies. It's much healthier to lose weight at a sustainable, slow rate.
Weight loss studies surrounding intermittent fasting have typically investigated the 5:2 diet or alternate-day fasting interventions lasting three to six months. The research revealed that it takes four to six months to lose 20 pounds with no change in diet.
You Can Lose Up to 24 Pounds
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 healthy manner, Jim said. So for three months, or about 12 weeks, a healthy goal is 12 to 24 pounds.
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.
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.
Skin laxity can change after losing about 30 pounds, says Desai. “If you notice changes in larger areas of the body, like arms, abdomens, thighs, and buttocks, you may get that change in the face as well.”
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.
Drinking at least 64 ounces (eight cups) of water every day may help with weight loss. Downing liquid is not the only way to meet this goal. About 20 percent of your hydration needs can be met through your diet, says Caroline Susie, RDN, a national spokesperson for the Academy of Nutrition and Dietetics.
Drinking Water Can Make You Burn More Calories
Drinking water increases the amount of calories you burn, which is known as resting energy expenditure ( 4 ). In adults, resting energy expenditure has been shown to increase by 24–30% within 10 minutes of drinking water.
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.
It is possible to lose 20 lbs. of bodyfat in 30 days by optimizing any of three factors: exercise, diet, or drug/supplement regimen. I've seen the elite implementation of all three in working with professional athletes. In this post, we'll explore what I refer to as the “slow-carb diet”.
According to many experts, losing 1–2 pounds (0.45–0.9 kg) per week is a healthy and safe rate (1, 2, 3 ). Losing more than that is considered too fast and could put you at risk of many health problems, including muscle loss, gallstones, nutritional deficiencies and a drop in metabolism ( 4 , 6 , 7 , 8 ).
So what is the magic number to lose weight and keep it off? According to the Centers for Disease Control and Prevention (CDC) , it's 1 to 2 pounds per week. That means, on average, that aiming for 4 to 8 pounds of weight loss per month is a healthy goal.
Eat Fewer Carbs
To help lose 20 pounds in two months, you should try to limit refined carbohydrates such as white rice and pasta and focus on fiber-rich, complex carbohydrates such as beans and whole grains. Dietary fiber can also reduce hunger, decrease caloric intake and help prevent weight gain.
The National Institute of Health recommends setting realistic weight goals and that is to say that losing 50pounds in 3 months is neither a realistic nor an achievable weight goal. The National Institute of Health recommends trying to lose about 5% to 10% of your total body weight in a period of six months (6).
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.
“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.
Without the volume to support it, skin can sag and fold, leading to facial folds, wrinkles, turkey neck, and jowls. The combination can make a big difference in your facial appearance, and for some people it can have a much more dramatic effect, making you look more than just four years older.
Losing a lot of weight can leave a person with saggy skin, especially if weight comes off quickly. Unfortunately, there's no magic lotion or cream that can get rid of extra skin after weight loss. You should keep seeing improvement, but you may need to give it more time.
