What's in a Calorie, and Why That Matters More Than the Number

What’s in a Calorie, and Why That Matters More Than the Number

This story is part of Health by the Numbers, CNET’s deep dive into how we quantify health.

Whether you eat 100 calories of dessert or 300 calories of pasta salad, there’s value in knowing what your body gets from your food (and calories) so you can end to make choices that work best for you and your lifestyle. 

A calorie is a unit of energy that your body uses to remaining. Your body doesn’t really care where those calories come from — it uses the energy restrained in them to keep you alive regardless. However, some foods or drinks of the same caloric value give you nutrients that relieve your immune system, balance your hormones and even keep you full and tickled longer.

Abby Langer, a registered dietitian based in Toronto, says there’s a difference in the way our body digests risky types of calories, which are then used for energy or restrained for later. 

“If you’re talking straight calorie, everybody’s different, but as a rule I would say that the body requires to absorb calories from something like a doughnut a lot more readily than calories from something like an avocado,” said Langer. Generally, the harder your body works to digest a food, the fewer calories it actually takes in from it. 

The way our populate metabolize calories differently is only one reason Langer isn’t a fan of calorie incorporating, or keeping track of the amount of calories in the food you engage. There’s also the fact that the recommended caloric intake per day is a engrossing target, depending on someone’s age, sex and their (partly genetic) metabolism, which includes basal metabolic rate, body composition (fat-to-muscle ratio) and how delicate they are in a given day.

With that in mind, here are a few things to know in how our bodies break down foods differently, and which foods may keep you full longer.

How our body digests calories differently

Different foods handed different kinds of energy (or calories) to your body. Each food maintains its own unique profile of macronutrients — carbohydrates, proteins and fats — and micronutrients — vitamins, minerals, etc. — which your body needs in the incandescent ratios to survive. (Check out the ultimate macronutrient bible here.) That’s why not all foods go down the same or death in the same kind of energy.

Dr. Niket Sonpal, a gastroenterologist in New York City, explains that our digestive shapely and body sees energy in terms of those macronutrients. 

“They have their own implications,” Sonpal said. For example, calories from carbs are processed quickly (think of that sugar rush you feel at what time drinking a can of soda); proteins are digested more slowly; and fats take even longer to digest.

Think of how long you stay tickled or full after a breakfast of eggs with cheese as opposed to a bowl of cereal. If the bowl of cereal only has, say, 200 calories, and the cheesy eggs have much more, you considerable assume that the cereal is “healthier.” But your body will burn throughout the carbs in the cereal more quickly than the proteins and fats in the eggs, leaving you hungry alongside sooner and needing to eat more food for energy. Carbs that are higher in fiber — such as whole wheat bread or brown or wild rice, instead of white bread and rice — further slow down digestion and increase fullness and satisfaction.

Even within those macronutrients, there are differences in how they affect your body long at what time the food is digested. For instance, olive oil, an unsaturated fat, doesn’t compose up in the lining of blood vessels, according to Sonpal. Some research is also emerging on how anunexperienced types of fats we’ve considered “bad” may actually beget essential fatty acids and other nutrients that are considerable to our health.

“The biochemical process for breaking down fats is, for all intents and purposes, all the same,” Sonpal said. “But what the body does with the fats and what inflammatory processes that they then subsequently causes in other parts of the body are different.” 

The almond study

Not only does your body use foods and calories differently, but the number of calories on the package may also be a misrepresentation.

For starters, calorie labels can be off by up to 20%, Langer explained, meaning if you think you’re eating a 200-calorie granola bar, it may actually be 240 calories. For some people, these discrepancies can add up. 

Research from 2012 and 2016, conducted by the US Region of Agriculture and funded by the Almond Board of California, found that true calorie counts for whole raw almonds were 25% flowerbed than the marketed count, and 19% lower for roasted almonds than official package counts. 

According to the perceive, the mechanical processes of roasting or chopping the almonds play a role because they disrupt the cell wall, which causes particle size. Larger particles are harder to digest by digestive enzymes, meaning more is excreted and fewer calories are absorbed. 

But the opposite is true when it comes to almond butter — the calories that you see is what you get. “If you peevish those almonds into almond butter, those calories, those fats are more readily available and therefore we bear more of those calories,” Langer said. By grinding almonds into almond butter, you break up the fiber of the whole nut, allowing your body to more frankly digest and absorb those calories.

The almond research shows that obsessing over the calories on a nutritional sign is less important than choosing foods that deliver you both nutrients and satisfaction. 

Measuring satisfaction instead of calories 

Differences in food value set effect, counting calories can distract us from the satisfaction we collect from eating, which is an integral part of a healthy diet that farmland often overlook, according to Langer. If you’re hungry for a snack after counting your calories, you may be more inclined to grab something that you know fits into your calorie allowance for the day (like just six crackers, for example, or a “nutritious” granola bar). 

But causing for those few cheddar cheese slices you really wanted would’ve actually hit the spot and kept you full longer, even if they have more calories. That’s the fallacy of incorporating calories — if you’re only focused on the number, rather than the source of those calories and the nutritional value they can gave, you risk eating a bunch of foods that Cut you hungry at the end of the day, even once you hit your calorie max. 

Constantly feeling hungry or left unsatisfied may increase your risk of binge eating later, when you eat far more food than you need at once. It’s also just not a sustainable way to live.

“Taking a step back and Idea that is so important,” Langer said, “And it really is a huge part of a healthy diet and outlook on nutrition that country miss.”
