Watts to calories burned - simple answers to questions

How many calories is equal to 1 watt?

0.24 calories



“The 3,500 calories per pound rule is wrong” The first surgical attempt at body contouring was in 1921 when a dancer wanted to improve the shape of her ankles. The surgeon apparently scraped off too much tissue and tied the sutures too tight, resulting in necrosis, amputation, and the first recorded malpractice lawsuit in plastic surgery history. Today's liposuction is much safer - only about 1 in 5,000 patients kill, mostly for unknown reasons - a blood clot in your lungs or perforations in your internal organs.

Liposuction is currently considered the most popular plastic surgery in the world, and its effects are, in fact, only cosmetic. A study published in the New England Journal of Medicine evaluated obese women before and after losing about 20 pounds of fat from their bodies, resulting in nearly a 20% decrease in their total body fat. Typically, you will only lose 5-10% of your body weight in fat and you will get significant improvements in blood pressure, blood sugar, inflammation, chole sterol and triglycerides, but liposuction sucks: none of these benefits showed up after massive liposuction.

This suggests that subcutaneous fat, the fat under our skin, is not the problem. The metabolic effects of obesity come from the visceral fat that surrounds fat, or they even invade our internal organs, like the fat that marbles our muscles and liver. The way you lose that fat, dangerous fat, is by eating fewer calories than you are burning.



Anyone who has seen The Biggest Loser Shows knows that they are restricting enough calories and working out hundreds of pounds can be lost. Similarly, there have been cases in the medical literature of what some refer to as 'super obesity' in which individuals have lost up to 374 pounds, largely without professional help and discouraged from cycling two hours a day and the pounds a month for years Reduce intake to 800 calories a day, which is roughly what some concentration camp prisoners got during World War II. When Oprah triggered a weight loss on TV, he pulled out a cart full of fat, which represents the 67 pounds she got with a very low calorie diet has lost.

How many calories did she have to cut off in four months to achieve this? Consult leading nutrition textbooks or contact trusted authorities like the Mayo Clinic and you will learn the simple rule of weight loss: one pound of fat is 3,500 calories. Quote from the Journal of the American Medical Association: A total of 3500 calories equals 1 pound of body weight, meaning that if you reduce your intake by 500 calories a day, you will lose 1 pound per week. 500 calories per day x 7 days = 3500 calories, or 1 pound of body fat.

The simple weight loss rule that just isn't right. The 3,500 calorie rule goes back to a 1958 paper that just noted that human adipose tissue is 87% fat, so a pound of body fat would be about 395 grams of pure fat. Multiply that by nine calories per gram of fat, you get an approximation of 3,500 calories per pound.



The fatal flaw that leads to dramatically exaggerated weight loss predictions is that the 3,500 rule does not take into account that changes in the calorie-in equation of the energy balance equation automatically lead to changes in calories-out, for example a slowdown in the metabolic rate that is associated with a weight loss known as metabolic adjustment. This is one of the reasons for the weight. Imagine, for example, a 30-year-old sedentary woman of average height who weighs 150 pounds.

Under the 3,500 calorie rule, if she cut 500 calories from her daily diet, she would lose a pound a week or 52 pounds a year. In three years it would go away. It would go from 150 pounds to minus 6.

Obviously, that doesn't happen. What would happen is that instead of losing 52 pounds for the first year, she would likely only lose 32 pounds and then stabilize at around 100 pounds after a total of three years. That's because you need fewer calories to exist as a thin person.



It involves simple mechanics, much like how a Hummer uses more fuel than a small car --- think how much more effort it would take to just get out of a chair, walk around the room, or climb a few flights of stairs with a 50-pound- Backpack to rise. It's no easier than carrying 50 pounds in front of you lie at rest, sleep soundly, there's just less of your body to hold on to as we lose weight. Every pound of fat tissue lost can mean your body has to pump blood one mile less every minute.

Moving thinner bodies uses fewer calories. So if you lose weight by eating less, you end up needing fewer s. That's what the 3,500 calorie rule doesn't take into account, or think of it differently, a 200 pound man starts out, 500 calories more a day.

It's like a big lemonade or two donuts. According to the 3,500 calorie rule, in 10 years it would weigh over 700 pounds! That doesn't happen because the heavier it is, the more calories it burns just by passing it. When you're a hundred pounds overweight, it's like the thin person in you trying to walk around balancing 13 gallons of oil or lugging a sack of 400 chunks of butter around wherever you go.

It takes about two donuts extra energy just to live on 250 pounds, and that's where he would plateau if he persevered. So weight gain or weight loss for a given calorie surplus or deficit is a curve that flattens out over time rather than a straight line up or down. Even so, the 3500 calorie rule keeps popping up. even in obesity magazines.

Public health researchers used it to calculate how many pounds many ildren could lose each year if, for example, fast-food children's meals were swapped for apple slices instead of french fries. They thought two meals a week could add up to about four pounds a year. The actual difference - researchers funded by the National Restaurant Association were no doubt pleased to point out - would probably add less than half a pound, ten times less than the 3500 calorie rule would predict.

The original article was subsequently withdrawn.

How many watts does it take to burn a calorie?

1 watt (W) = 0.24 calories per second (cal/sec)

How many calories is 300 watts?

A rider putting out 200 watts for an hour will burn roughly 700 calories. For rides over two hours, says Lim, aim to replace about half your calories burned per hour.11.03.2016

How many calories do we really burn when we ride a bike? Well, we know it's a great way to lose weight, so the short answer is probably pretty much. But how do we really calculate it? How do we know how? a lot of carbohydrates that we have to consume while driving so that we don't run out of energy and hit the wall? - Yes. Put simply, a calorie is a unit of energy.

The more calories a food contains, the more energy it contains. And to say it again, we can calculate exactly how much energy it takes to ride at a given pace. (Funky music) - Pedaling a bike requires strength.

This is measured in watts. You can roughly assume that producing one watt of power burns four calories for one hour. It doesn't sound like much, but if you cover 10 miles each way, an hour on a flat road requires about 40 watts. 15 miles an hour about 100.

And 20 miles an hour on a flat road about 210 watts. So driving 10 miles in an hour requires 140 calories. 15 mph 350 calories and 20 mph about 700.

Knowing exactly how many calories you are burning requires quite specialized technology. That usually means a power meter like the one Matt and I use on the ride today. They are a pretty big investment, however, so an alternative is to use a flat road to give you a rough idea of ​​your calorie consumption.

However, as soon as you go uphill, whether slowly or downhill, or you have a strong tailwind or headwind, it will be very different. Instead, you could get a rough idea of ​​your heart rate - yes, this is a really long established method that takes your age into account. Your weight and how long you actually exercised.

If you include your average heart rate in the mix, you can get a really good idea of ​​how many calories you burned. - To give you an example, I'm 36 years old, I weigh 70 kilograms and to get an average of about 20 miles per hour, or 210 watts on a flat road, for me personally it only requires an average heart rate of about 140 beats each Minute at 770 calories per hour - so it's pretty clear there are some inaccuracies here. In fact, there is a lot of inaccuracy across the board with all of these methods.

But especially the heart rate. Take, for example, one person comparing to the next. Some people have really low heart rates, compare ed someone else, but that wouldn't affect their fitness in any way.

And then you have to look at your own heart rate. It could be changed based on your level of fatigue or even your body temperature, but what about performance? Surely this actually measures an achievement. Well, yes, but in order to calculate calories from performance, there is an assumption about your body's efficiency.

That is, how many calories are wasted creating this feat. The reason this is just an assumption is because people's efficiency varies by up to 30 percent - to put that in context, this is the difference between the need of 850 calories for an hour with 200 watts or just 600 calories three extra of these energy gels, every hour. Now there is one final element that complicates things even more.

You don't stop burning calories when you get off your bike. You burn calories just to stay alive, but certain types of exercise increase your metabolism. Effect They make your body burn more calories even when you are resting in bed.

This is because high-intensity exercise causes muscle damage, and it takes energy to repair, and you may find that you burn more calories for the next 24 hours as well. And if that's what you really want, high intensity intervals are what you need. If you ever want to accurately measure the amount of calories you burn while cycling, you need to know the amount and types of gases you exhale and the relationship between oxygen and carbon dioxide.

And as you can imagine, this would require some pretty specialized equipment, which will most likely be done in a laboratory. And let's be honest. Do you really have to be that specific? - Probably not, but knowing roughly how many calories you burn while riding will help you know how much to eat or how much energy to drink that you need to consume so as not to lose energy while riding.

In fact, every 90 minute drive requires some kind of carbohydrate intake, even if your primary goal is to lose weight. And if that's the case, it's restricting calories off the bike, that will be better. - So should you go eat some cake? - Yes.

Anyway - If you have not already subscribed to the Global Cycling Network, please do so so you will not miss any of our articles. And you can do this by clicking on the globe.- Yes, and if you want to aim high- intensity indoors, on your indoor trainer, down there we have the perfect article for you.

On the other hand, if you want to know the best places to eat while you're on your bike, you can find it right down there. - And tip, it's probably a café - No, actually on the bike - Oh - Okay.
