How To Calculate Percent Loss of Weight?

One of the most common problems of our time is losing weight. It has become so common that there are now TV series online where overweight people compete for prize money. As a general rule, each participant’s percentage of weight loss is compared to see who is in the lead and who will end up being the winner. As a result, many people all over the world are interested in how to figure out their weight loss percentage. This article will help you if you are one of them. So, you might ask, how do you figure out the correct percentage of weight loss? Continue reading to find out!

How does the Calculator work?

To fitness succeed out your weight loss percentage, you subtract your current weight from what you weighed when you first started trying to lose weight. This number is then divided by your starting weight, and the result is multiplied by 100. This will tell you how much weight you’ve lost. This equation can be written like this:

Weight Loss Percentage (%) = [(Start Weight – Current Weight) / Start Weight] 100

If the calculator gives you a number that is greater than zero, it means that you have gained weight. If the number is less than zero, it means that you have lost weight.

Take a look at an example. You used to weigh 200 pounds, but now you only weigh 180. So, take your current weight, 180, and take it away from your starting weight, 200. This gives you 20. You’ve lost 20 pounds. The next step is to divide 20 by your starting weight, which gives you 0.10. Lastly, you get 10 if you multiply 0.10 by 100. You’ve lost 10% of the weight you started with.

How do you make a weight loss chart?

  • Open a new spreadsheet in Excel on your computer.
  • In Row 1, Column A, type “Date.”
  • Write the date in Column A every time you weigh yourself.
  • In Column B, write your weight for each date that goes with it.
  • Move the cursor over the box that says “Date.”

How To Calculate Percentage Of Weight Loss: Formula

So, if you want to figure out how much weight you’ve lost, you need to do a few things (3):

  • Find out how much weight you have lost.
  • Divide this number by how much you weighed at first.
  • The percentage is found by multiplying the answer by 100.

Let’s think about a person who weighs 200 lbs. to help us understand. He or she then loses 50 pounds, so the formula is (50 pounds/200 pounds) *100 = 25. The result means that the person has lost 25% of their weight. This person has lost 25% of the weight he or she started with.

What Can Go Wrong?

If you decide to make it a competition, you may find that it motivates you and helps the people who take part lose weight more effectively. But this kind of weight loss method can sometimes lead to a number of problems. For example, people who try to lose weight can pick up a number of bad habits.

Some people may train more than they need to. It is well known that muscles need time to rest and heal. When you do a lot of physical work, your muscles break down, you lose fluid, and your glycogen stores, which your body uses for energy, run out. This puts a lot of stress on your body, which is why you need to give it enough time to recover between workouts. This is when your body gets used to the stress of your workouts and starts to feel the effects of your training. If you don’t take days off to rest, you could get overtraining syndrome, which is hard to get rid of. This syndrome can cause headaches, depression, insomnia, irritability, joint and muscle pain, loss of appetite, and more. By exercising too much, you make it much more likely that you will have this syndrome (4, 5).

Individualized Measures

Majumdar, a spokesperson for the Academy of Nutrition and Dietetics, says that losing weight is very different for each person, and it will be harder if you compare yourself to other people. People lose at different rates and in different amounts, and comparing yourself to others is rarely helpful and can be discouraging. When you figure out your percent loss, you can only compare yourself to yourself.

To figure out your weight loss percentage, divide the amount of weight you’ve lost by the weight you started out at, then multiply that number by 100: (pounds lost/weight at the start) x 100.

She says that everyone should start by trying to lose between 0.5 and 2 pounds per week. “Losing more than that isn’t realistic, and setting goals higher than that will make you feel bad and make you lose muscle.” Also, a person’s health improves for diseases like diabetes when they lose between 5 and 10% of their body weight. This is different from just saying you lost 10 pounds because 10 pounds for someone who weighs 300 pounds is a 3.3% loss and will have less of an effect than the same weight loss for someone who weighs 150 pounds, which is a 6.7% loss.

Why is the percentage of weight loss important?

This is a way to figure out how much of your starting weight you have lost compared to what you weigh now. This percentage can help you figure out if you are losing weight in a healthy way.

Some people say that a 10% weight loss is enough to start with and that anything more than that, especially in a short amount of time, could be a sign of an extreme weight loss that could lead to or cause health problems.

What is a healthy weight loss percentage?

You are more likely to get type 2 diabetes, a stroke, mental health problems, and many types of cancer if you are overweight or obese. Heart disease, metabolic health problems, and cancer are all more likely to happen if you have a lot of fat around your middle. People who are overweight, on the other hand, are less likely to get type 2 diabetes, heart disease, asthma, and chronic kidney disease if they lose weight.

The Centers for Disease Control and Prevention (CDC) says that losing as little as 5–10% of your total body weight can be good for your health and lead to benefits like lower blood pressure, cholesterol, and blood sugar.

They say that you should try to lose one to two pounds per week. They say that this way of doing things is more likely to work than trying to lose weight quickly. How much of your body weight this is worth depends on how much you weigh right now.

Losing weight slowly is healthier and more likely to last than “crash dieting.” This is because your metabolism slows down more when you lose weight quickly than when you lose weight slowly. This means your body gets used to using less energy. This slowing of your metabolism can last for years and cause you to gain weight, often more than you lost.

Are there better ways to track weight loss and improve your health?

What does your weight really tell you about yourself? Everyone is different, and your healthy weight range will depend on things like your age, sex, metabolism, and how active you are. If you work out more, you may be building up more muscle mass. Since muscle weighs more than fat, even if you’re losing fat, your weight could go up.

Using BMI to figure out if your weight is healthy is a good place to start, but it doesn’t take into account your unique body and lifestyle. There are, however, other ways to look at your health and weight.

Some more practical ways to keep track of your health improvements are:

  • figuring out how much your strength has grown if you have been working out.
  • Check how your clothes fit you (maybe you changed the belt notch).
  • deciding if you feel healthier or have more energy
  • Take a look at how much your diet has improved

The ZOE program gives you scores for your meals based on how well they work for your body and metabolism. This can help you find the best foods for your body and improve your diet.

Why Is It Useful?

This formula is one of the most used ways to estimate how much weight you will lose. You can use this method to measure how much weight you lose not just in pounds but also as a percentage. If you are trying to lose weight with friends or family, this is a fun way to do it as a friendly competition, just like on TV. Even if one person weighs 200 lbs and another weighs 150 lbs, they can both still compete because the results will be measured in percentages. This is also a good way to keep yourself going and see how far you’ve come.

Is Percentage Better?

Farrell Allen, who teaches at Rosalind Franklin University of Medicine and Science and Germanna Community College and is a spokesperson for the Academy of Nutrition and Dietetics, says, “I would say no because many people get confused by percentages.” “I would only use whole numbers to keep track of my weight loss.” She also says, “The scale only has one number. Be aware of the number it shows, but don’t focus too much on it.”

Majumdar is mostly in agreement. In fact, she stresses that “monitoring behavior can be more useful than monitoring outcomes.” For example, instead of keeping track of weight loss, which can change a lot from week to week and sometimes doesn’t happen at all, “you could be keeping track of a behavior, like steps walked per day, and notice that you had a less active week. That can lead to changes, like taking a walk at lunch, getting off the bus or train one stop early, or taking the stairs, instead of getting frustrated with the scale.


Calculating your weight loss as a percentage may help you lose weight in a more controlled way than just looking at pounds or kilograms. This is because it shows you how much you’ve lost as a percentage of your starting weight.

The easiest and simplest way to do this is to use ZOE’s calculator for weight loss percentage.
