Is it possible to lose 45 pounds in 3 weeks?

It is not possible to lose 45 pounds in 3-weeks. This is much more than the 3- 6 pounds experts recommend you lose in 3 weeks and is considered unsafe for most people.

 

It takes a calorie deficit of 3,500 to lose a pound of fat. You need a higher calorie deficit of 157,000 to lose 45 pounds. In 3 weeks, this comes down to a daily calorie deficit of 7,500. Most people will find it almost impossible to create this high-calorie deficit even with diet and exercise.

 

You have to eat less to lose weight. Most experts recommend a moderate calorie reduction of 500 – 1000. Even with a daily calorie reduction of 1000, you still have an extra 6500 calories to burn with exercise to lose 45 pounds in 3 weeks.

 

While exercise can help you burn calories, you have to do it at the right intensity and duration. A 185-pound person, for example, burns approximately 503 calories in 30 minutes, jumping rope.

 

This person would have to do this workout for at least 6.5 hours to burn enough calories to lose 45 pounds in 3 weeks. It is much more than the 200 minutes most experts recommend healthy adults spend exercising weekly.

 

While these extreme measures can help you lose 45 pounds in 3 weeks, they’re not recommended. As a result, you’re more likely to gain all the weight back. Also, these extreme measures can affect your health.

How long does it take to lose 45 pounds?

On average, it takes 6 – 11 months to lose 45 pounds. It is a safe amount of time for most people to lose 45 pounds. It’s also in line with the CDC (center for disease control and prevention) guidelines for healthy weight loss.

 

With a daily calorie deficit of 500, expect to lose 45 pounds in 11 months. Double the effort to a daily calorie deficit of 1000 to lose 45 pounds in 11 months.

 

However, keep in mind that these numbers can vary greatly. Several other factors affect how quickly you lose weight. These include factors such as; weight, age, gender, height, and activity level.

 

Due to these factors, some people might lose 45 pounds much faster or take longer. A person who weighs over 300-pounds, for example, will not lose 45 pounds at the same rate as someone who weighs 150-pounds. The heavier person burns more calories as their energy needs are higher.

 

In the same way, a person who exercises daily and stays active will not lose 45 pounds at the same rate as another with a sedentary lifestyle with little to no activity.
