The CICO food plan is brief for energy in, energy out, and it’s a easy idea based mostly on the precept of power steadiness.
The thought is that in case you devour fewer energy (energy in) than your physique burns (energy out), you’ll shed extra pounds.
On the flip facet, in case you eat extra energy than you burn, you’ll acquire weight. And in case you match the energy you soak up with the energy you burn, you’ll keep your present weight (1).
How It Works
CICO doesn’t limit particular meals or macronutrients like different diets, comparable to keto or paleo. As an alternative, it emphasizes calorie monitoring (1).
We’ll undergo the best way to decide your caloric wants and get the perfect outcomes with this weight administration technique.
Understanding caloric consumption and expenditure
On the coronary heart of CICO is the steadiness between caloric consumption—AKA the energy you devour from all the things you eat and drink—and caloric expenditure, or energy out. These are the energy your physique makes use of to gasoline all the things from respiratory to working a marathon (1).
Daily, your physique burns energy simply to remain alive. Your basal metabolic charge (BMR) is the variety of energy your physique makes use of to carry out these every day capabilities (1). (You’ll discover ways to calculate this under.)
The quantity of muscle you’ve got performs a task in your metabolism as a result of muscle tissue is metabolically lively—it burns energy at relaxation (6).
One other think about your metabolism is your physique dimension. Bigger our bodies require extra energy to keep up their dimension, which implies in addition they burn extra energy (6). As you shed extra pounds, your physique’s caloric wants change, so that you’ll require fewer energy. Throughout a weight reduction journey, you’ll have to recalculate your BMR now and again if you wish to keep a calorie deficit (7).
Outdoors of your BMR, further energy are burned by way of bodily exercise, together with train, strolling, and even chores like cleansing and cooking. That is the a part of your caloric expenditure that you’ve got essentially the most management over (6).

As soon as you recognize your BMR, you may add the energy you usually burn in your every day actions to seek out your complete every day power expenditure. That’s a extra correct reflection of your caloric wants than your BMR.
