What is the CICO (Calories In, Calories Out) Diet?
The CICO diet stands for ‘calories in, calories out’ and is based on the premise of eating fewer calories than the amount you burn. Scientifically, burning more calories than that you consume causes weight loss. But the idea that you can eat whatever you want and lose weight still has some limitations. Fitness trackers and apps all tell you how much you’ve burned off and how much you’re consuming so the diet is popular among lots of people.
The concept isn’t entirely new but interest in it has regurgitated following popular Reddit threads vouching for its success. The CICO subreddit even has more than 16,000 followers. It certainly sounds easy – you get to munch limited portions of whatever you like and then burn it all off, shedding weight. It’s not the most sustainable though as it means you’re not focusing on quality and the types of foods you’re entering into your system.
What is the CICO diet?
A complete simplification of weight loss, CICO stands for calories in, calories out and it’s a dieting concept that’s been around for decades. Because losing weight ultimately comes down burning through more calories than you’re eating, “there is a lot of truth to it. It’s been gaining steam as a trendy diet,” she says. There’s no book or app or celebrity spokesperson: People just calculate their needs online, and then track how much they eat, drink, and work out in a given day.
How CICO Works
All the cells in our body require energy to function. This energy is constantly powering important reactions and processes in the body. We provide this energy to the body through food and burning stored fats. Any unused energy remaining in the body becomes stored as fat.
The calories-in and the calories-out principle is a basic equation. Calories-in refers to the consumption of food and drinks, where energy is being added. Calories-out refers to the energy that is being used in the body during activity and rest. If more energy is used than added, fat stores are burned away as extra fue.
Calories-out is also known as your total daily energy expenditure or TDEE. When your TDEE decreases or food intake increases, you may begin to gain weight.
CICO relies on the principle of “energy imbalance.” In CICO, daily energy intake should be less than TDEE. Burning off more calories than you consume will result in weight loss.
According to proponents of CICO:
Weight Gain: CALORIES IN > CALORIES OUT
Weight Loss: CALORIES IN < CALORIES OUT
Weight Maintenance: CALORIES IN = CALORIES OUT
Decreasing the number of calories consumed is the most common way to lose weight. The body must burn 3500 calories to shed 1 pound of fat. For example today you eat 2000 calories and burn 2500 calories. This leads to a total loss of 500 calories. If this is done for a week (500 calories burned x 7 days) you will burn 3500 calories, and 1 pound of fat.
Let's start with the basics of calorie counting
Calories are units of energy–found in food–that fuel everyday activities. Breathing? That burns calories–as does eating and hitting the gym.
Basal metabolic rate or BMR is the amount of calories your body burns to stay alive. This figure is individual specific and determined by a number of factors including height, weight, and age. Online calculators offer an estimate, and some doctors use breathing machines that deliver more precise and customized BMRs.
Lifestyle factors like physical activity need to be accounted for since you're probably not lying in bed all day. Again, online calculators and formulas offer rough estimates of how many calories your body uses. Losing weight requires eating fewer calories than your body needs to maintain its activity level.

Most diets work because of a calorie deficit. However, calories as we know them are so arbitrary.
The calorie was invented a really long time ago and isn’t necessarily accurate in terms of how our bodies metabolize each individual food.
Research from the U.S. Department of Agriculture found that people absorb only about 75 percent of the calories found in almonds, according to a 2016 paper published in the journal Food & Function.
We’re learning so much more about how calories are absorbed,. Your body takes in more calories from food that's been processed, or broken down from its natural form, she explains.
So if you have a smoothie you’re going to absorb a significant portion of those calories compared to if you eat that food raw or cooked.
Emerging research shows our bodies handle ultra-processed items like chips or Twinkies differently than kale or bananas.
Those [packaged snacks] are going to be viewed very differently on a cellular level. The National Institute of Health found that ghrelin, a hormone that drives hunger, is higher when people consume ultra-processed foods compared to after eating a well-balanced diet, according to 2019 research published in Cell Metabolism.
Heavily-processed foods high in sugar, fat, and salt, may spike insulin levels and cause your body to store more fat. Then, you have to consider the benefits of a fiber.
Fiber-rich foods provide a certain level of satiety and fullness. The nutrient also promotes healthy gut bacteria, which scientists believe may determine a person's weight.
What CICO gets wrong
The problem with the CICO mentality is that it reduces weight loss to a calorie equation, when not all calories are created equal.
We now know that the quality of the calories you consume, as well as the macronutrient balance and timing—all impact metabolism, satiety, and how your body utilizes calories,. For example, 300 calories from a blueberry muffin made with refined flour and sugar does not affect your body the same way that 300 calories from cooked oats topped with almonds and blueberries do. [CICO] is an outdated way of thinking.
You also have to consider how food choices affect your body beyond weight loss. Eating all junk, but keeping it low-calorie, will still wreak havoc on things like your skin, your mood, your gastrointestinal functions.
Certain macronutrients are important for things like tissue repair, and muscle recovery and growth.
If you're doing strength training and other physical activity as part of your healthy routine—which also boosts your metabolism and helps with weight loss—you're doing yourself a disservice by not thinking about the food you're putting on your plate.
So can you lose weight just by keeping CICO in mind? Sure, it's possible. But would I recommend this to my patients? Definitely not.
People lose weight after increasing their total calorie intake or break through a weight-loss plateau by altering the quality, balance, or timing of their calories, without reducing the total amount. To sum up: It's not as simple as a math equation.
What are the potential benefits of CICO?
Experts agree that the idea behind the CICO diet is, for the most part, true: Eating fewer calories than what your body needs to survive results in weight loss. If you’ve been defeated by restrictive diets in the past, the CICO mindset—which avoids the concept of “forbidden” foods—might help. For someone who’s completely confused about conflicting nutrition messages, CICO can be a very simple, easy place to start.
Even just tracking calories for a few days can be very eye-opening. People are often surprised by how many calories are in their food and how much is burned by exercise. Knowledge is power. If you’re aware of what’s on a menu, that helps you to make better choices.
A better way to watch your calories
For the average woman who wants to lose weight, very suggests aiming to consume roughly 1,500 calories a day: That number might be a little bit up or down, depending on whether you're taller or shorter, or how much you exercise, but 1,500 calories is a great starting point.
However, instead of tallying up the calories from every single food you eat, Practicing "calorie consciousness." Look at your plate and ask yourself, Do I have a smart carb, protein, healthy fat, and vegetables? Then ask yourself, Do the portions of each look reasonable? And do vegetables take up the majority of the plate?
If you look at your plate and you have what you can guesstimate is a half-cup of a grain, that's going to be roughly 150 calories; if you see a reasonably sized piece of protein, it's likely about 3 ounces, or about 150 calories. And if you see a lot of vegetables, topped with just a little bit of fat, like a drizzle of olive oil, you're probably adding up to about a 400 to 450 calorie meal. Developing this kind of calorie awareness can help you get a good balance of nutrients to nourish your body, while still staying on track to lose weight that stays off.
