To find your "real weight," weigh yourself consistently at the same time (morning, after using the bathroom, before eating/drinking), on a hard, flat surface, wearing minimal/same clothing, using the same reliable scale, and track the trend over time, as daily fluctuations are normal; also consider body measurements like waist size for a fuller picture of health, according to Healthline and the British Heart Foundation.
Morning Routine: Weigh yourself first thing in the morning after using the bathroom for the most accurate reading. Track Your Weight: Record your weight after each weigh-in. Calculate Weekly Average: Add up your recorded weights for the week and divide by the number of weigh-ins to find your weekly average.
Body mass index (BMI)
A BMI calculation provides a single number, which the Centers for Disease Control and Prevention (CDC) categorizes as follows: A BMI of less than 18.5 suggests underweight. A BMI of between 18.5 and 24.9 suggests a healthy weight range. A BMI of between 25 and 29.9 may indicate overweight.
Formula. Males: IBW = 50 kg + 2.3 kg for each inch over 5 feet. Females: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet.
The Best Time to Weigh In
You should step on the scale first thing in the morning. That's when you'll get your most accurate weight because your body has had the overnight hours to digest and process whatever you ate and drank the day before. And you should try to turn that step into a regular part of your routine.
At what time of the day are you heaviest? Generally speaking, people are at their heaviest after eating a meal and at their lightest after strenuous exercise where they sweat out their water weight.
Strictly speaking, body weight is the measurement of mass without items located on the person. Practically though, body weight may be measured with clothes on, but without shoes or heavy accessories such as mobile phones and wallets, and using manual or digital weighing scales.
A 75 kg (about 165 lbs) body weight can be healthy or indicate overweight, depending heavily on your height, muscle mass, and body fat, not just the number on the scale. For taller individuals with good muscle, it's generally healthy, but for shorter individuals with low muscle and high body fat, it could be overweight, as muscle weighs more than fat, affecting appearance and health metrics like BMI. Use online BMI calculators and consider body composition for a better picture of your health.
For example, if someone is 5'8” and weighs 200 lbs The BMI reading would be 30.4 which would put the person in the obese category.
Because we know that our mass is constant, it must be the gravitational forces that make our weight change. On Earth, the force of gravity on a one-kilogram mass is ten Newtons. So, if my mass is 70 kilograms, then the force of gravity on me makes my weight 700 Newtons.
A weight of 70kg can fall within the healthy weight range for various individuals. Height plays a significant role. A shorter individual might find a BMI of 70kg within a healthy range, whereas a taller person could potentially fall into the overweight or even the obesity category using the same metric.
Your weight is stable and isn't constantly fluctuating. You have a regular menstrual cycle. Your immune system is strong. You have stable energy levels.
The best time to weigh yourself is first thing in the morning after you've gone to the restroom but before you eat or drink anything. The reason for this is that your body has had enough time to digest all the food and drinks you've consumed from the day before all while you were getting your beauty sleep.
Calories consumed at night won't change your metabolism or count more than calories consumed during the day. Weight gain and weight loss comes down to a simple math equation, explains Day. “Too many calories taken in versus not enough expended on any given day, regardless of the time, will lead to weight gain.”
Gyms and leisure centres often have scales, but you might have to pay to use them. Health centres and pharmacies are likely to have private weighing areas and may have specialist or accessible options.
Individuals are usually considered morbidly obese if their weight is more than 80 to 100 pounds above their ideal body weight.
It is possible to gain weight but appear thinner if you are losing fat and building muscle at the same time. Since muscle is denser than fat, it can produce more weight in less space, causing you to look thinner while weighing more.
How to get your BMI down
In adults, overweight, or pre-obesity, is defined as a BMI of 25-29.9 kg/m², while a BMI ≥ 30 kg/m² defines obesity.
A male who is under 200 pounds or 90 kilograms. Generally used to refer to males who could be overpowered and taken advantaged of by other males who are above 200 pounds. Could also be used as a general statement about a male weighing approximately 140-160 pounds or 60-70 kilograms.”
An 80 kg (kilogram) human has a mass of about 176.37 pounds (lbs) or 12 stone 8 lbs, but "weight" technically refers to the downward force due to gravity, measured in Newtons (around 784 N on Earth), though colloquially, people use kilograms to mean weight. For adults, 80 kg often falls into the "healthy" to "overweight" range depending on height and body composition, with health charts showing ideal ranges around this value for various heights.
Your body loses significant water weight overnight through breathing and perspiration, so stepping on the scale first thing in the morning will often give you your lightest weight of the day.
In some people, particularly those who have been dieting or fasting, a meal that is high in carbohydrates, such as pasta or rice, can be stored as glycogen. Glycogen is stored with water, which causes an individual to gain water weight very quickly – as much as 2 pounds overnight.
It's completely normal to feel lighter and weigh a bit less in the morning due to overnight water loss and an empty digestive system. To get the most accurate picture of your progress, try weighing yourself at the same time each morning, ideally before eating or drinking.
