Is 13 stone a healthy weight?

For most adults, 13 stone is in the healthy BMI range only if you are about 6 feet tall or more. At shorter heights it falls into the overweight or obese range.

BMI is your weight in kilograms divided by your height in metres squared. Here is how 82.55 kg works out at different heights:

Height	BMI at 13 stone	Range
160 cm (5 ft 3)	32.2	Obese
165 cm (5 ft 5)	30.3	Obese
170 cm (5 ft 7)	28.6	Overweight
175 cm (5 ft 9)	27.0	Overweight
180 cm (5 ft 11)	25.5	Overweight
185 cm (6 ft 1)	24.1	Healthy
190 cm (6 ft 3)	22.9	Healthy

A BMI figure is a first check and nothing more. It treats muscle and fat as the same thing, so a person who lifts weights or plays a lot of sport can show as overweight while carrying little body fat. Waist size is a useful second check. Your GP can look at both, along with your age and family history.

How far is 13 stone from the top of the healthy range for your height?

Take the top of the healthy range for your height away from 82.55 kg. The answer shows how many kilograms sit above it.

Height	Top of healthy range	Difference at 13 stone
165 cm (5 ft 5)	67.8 kg	14.8 kg above
170 cm (5 ft 7)	72.0 kg	10.6 kg above
175 cm (5 ft 9)	76.3 kg	6.3 kg above
180 cm (5 ft 11)	80.7 kg	1.9 kg above
185 cm (6 ft 1)	85.2 kg	Inside the range

So a person who is 5 feet 9 and weighs 13 stone would reach the healthy range by losing about 6.3 kg, which is almost exactly one stone. Someone who is 5 feet 11 would need to lose less than 2 kg, or about 4 pounds.

How does 13 stone compare with the average man in England?

Thirteen stone is slightly below the average. National health survey figures put the average man in England at around 85 kg, which is about 13 stone 5.

That makes a 13 stone man roughly 2.5 kg, or 5 pounds, lighter than the national figure. The average woman weighs around 72 kg, or about 11 stone 5, so a woman at 13 stone is more than 10 kg above the average for women.

Keep in mind that the average adult in England is above the healthy BMI range. Being close to average is not the same as being a healthy weight for your height.

What does 13 stone mean in the gym?

At 13 stone, lifting your own body weight means lifting 82.5 kg. Gym plates are marked in kilograms, so this is a useful number to know.

On a standard 20 kg Olympic bar, body weight is the bar plus a 20 kg plate, a 10 kg plate and a 1.25 kg plate on each side. That adds up to 82.5 kg.

Strength sports also sort people by weight in kilograms. In powerlifting, one of the men’s classes has an upper limit of 83 kg. A 13 stone lifter, at 82.55 kg, fits just inside it with less than half a kilogram to spare. Many strength programmes also set targets as a multiple of body weight, such as squatting one and a half times what you weigh. For a 13 stone person that would be about 124 kg.

How does 13 stone fit with everyday weight limits?

Thirteen stone is under the limit for nearly all household products, most of which are rated for 100 kg or more.

A limit of 100 kg leaves 17.4 kg to spare at this weight. That matters when you are carrying something. A loaded rucksack, heavy boots and tools all count towards the total on a ladder or a loft floor. Many step ladders sold for home and trade use are rated to 150 kg, which covers a 13 stone person with plenty of room. Folding bikes and electric scooters often have lower limits of around 100 to 120 kg, including luggage.

Check the label or manual for the exact figure. Limits are nearly always given in kilograms, which is another reason to know yours.

Why might your weight read 13 stone one day and less the next?

Body weight normally moves by 1 to 2 kg over a day. Food, drink, salt, exercise and the time you last used the toilet all play a part.

A swing of 1 kg is 2.2 pounds. So a person whose true weight is 13 stone might see anything from about 12 stone 12 to 13 stone 2 without any real change in body fat. This is why a single reading tells you little.

For a fair picture, weigh once a week, first thing in the morning, on the same scales. Look at the trend over a month and ignore the small jumps from day to day.

Five per cent of 13 stone is 9.1 pounds, or 4.13 kg. Ten per cent is 18.2 pounds, or 8.26 kg.

Health professionals often set a first target of 5% because it is within reach and can improve blood pressure and blood sugar for people who are overweight. For a 13 stone person, hitting that target would mean a new weight of about 78.4 kg, or 12 stone 5.

What mistakes should you avoid with this conversion?

Do not round 6.35 down to 6. Thirteen times 6 is 78 kg, which is more than 4.5 kg below the real figure.

Two other slips are common. The first is halving the pounds to get kilograms. Half of 182 is 91, which is about 8.5 kg too high, because a kilogram is 2.2 pounds and not 2. The second is leaving off the spare pounds. Thirteen stone 9 is 86.64 kg, a full 4 kg more than 13 stone on its own.
