To lose 20 pounds in 1 month, you'd need to create an average deficit of 2,500 calories per day for 4 weeks.
Lean meats, seafood, poultry, legumes, eggs, nuts, and seeds are a few healthy sources of protein that you can easily add to your diet. Studies have shown that protein may promote feelings of fullness by reducing calorie intake, which can help contribute to weight loss.
Fruits, vegetables, whole grains, low-fat dairy and lean meats are all low-calorie dense foods that will help you lose weight. Fruits and veggies are mostly water-based and contain very few calories and very little fat--on the other hand, 1 g of fat is nine calories in itself.
Since there are about 3,500 calories in one pound, it would take you one week to lose one pound and 20 weeks to lose 20 pounds.
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.
Simply put, you can lose 20 pounds in several months by eating fewer calories than you do now and exercising vigorously for three to five hours per week using resistance training, interval training, and cardio training.
Its simple. You need to burn more calories than you consume every day for losing weight and fat.
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.
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.
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.
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.
If you take in fewer calories than needed, you will lose weight ( 1 ). Restricting intake to fewer than 1,000 calories daily can slow down your metabolic rate and lead to fatigue since you're not taking in enough calories to support the basic functions that keep you alive.
To lose 20 pounds in 1 month, you'd need to create an average deficit of 2,500 calories per day for 4 weeks.
“A generally accepted rate of healthy weight loss is a half-pound to one-pound per week. So, budget five-to-six months to achieve a 20-pound weight loss,” she says. McAllistre explains that losing weight slowly helps you keep the weight off.
You will need to create a deficit of 1167 calories each day to meet your goal. This goal can be met through dieting and exercise. If you are burning an average of 500 calories per day, then you'll need to eat 700 calories less than you usually need to maintain your current weight.
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.
