The Atwater system , as it's known, is used to estimate the number of calories in a particular sample of food by multiplying the amount of macronutrients carbohydrates, proteins, and fats by known constants. Every gram of carbohydrate in food, for example, is worth four calories.
Protein is also worth four per gram. Fats have nine calories per gram, and alcohol has seven. Because fiber isn't very digestible, it's counted as zero calories per gram. If you know how much of each macronutrient is present in a particular food, you can estimate pretty well how many calories that food had.
Although the Atwater system is only capable of estimating the number of calories in a particular food, it's generally considered to be accurate enough. There are chemical processes that allow scientists to measure each of them. They're a bit complicated, but you can read more about them in this fantastic explanation on Reddit. In short, food is weighed, chemicals are added that eliminate a particular macronutrient, and the food is weighed again.
The difference in weight indicates how much of that nutrient was present. The calculating of the calories you take in is fairly simple, as long as you accurately weigh and record your food. But most apps also offer measurements of how many calories you burn when you do exercise. You can see here how fitness apps calculate calories burned. You should take these calculations with a grain of salt, however. They are often not very accurate.
To understand how calories burned are calculated, you need to know about metabolic equivalents , or METs. These figures measure the number of calories burned compared to your resting metabolic rate RMR , or the number of calories you burn while you're just sitting down, doing nothing.
If you're doing an activity that requires three METs, you're burning three times as many calories per minute as you would by just sitting. There are published tables that assign MET values to different activitiesfor example, walking at 2.
Riding a bike at under 10mph is close to 4METs. And so on. The scale goes up to 23, which you'll hit if you're running a mile. Various MET tables include a wide range of things, from housework to taking classes to real estate services to bowling. If you want to find the metabolic equivalent for a specific activity, you just need to run a search online.
So, we now know that every activity has a MET value. This serves as a multiplier for your resting metabolic rate.
