Daily Calories for Adults — From Recommended Intake to Basal Metabolic Rate and How to Reduce Calories
"Doctor, I feel like I eat very little, so why do I keep gaining weight?" This is one of the most frequent questions I hear in the consultation room. It is very frustrating when you feel you are controlling your diet, but your weight does not move as expected. In fact, the amount we perceive as 'moderate' is often quite different from the actual figures our bodies require.
The Basic Principle of How We Consume Energy Daily
The first concept you must understand to lose weight is the Basal Metabolic Rate (BMR). This refers to the minimum energy consumed even when you are doing nothing and just breathing. According to one source, this BMR accounts for 60~70% of total daily energy expenditure. It is a larger proportion than one might think.
How much you can eat per day is determined by the total energy expenditure, which is the BMR plus your usual activity level. However, many people cling only to 'eating less.' If you blindly reduce intake while ignoring your body's basic metabolic capacity, your metabolic function may actually decrease, potentially turning you into a constitution that gains weight even when eating less later on. You must be very careful about this part.
Recommended Intake Based on Gender and Activity Level
Then, how many calories per day are appropriate for an adult? The recommended intake for Korean adults is commonly known as 2500kcal for men and 2000kcal for women. However, these are merely averages. In reality, there are significant differences depending on an individual's height, weight, age, and activity level.
I will organize the reference figures by activity level.
For adult men (based on those in their 30~49s, 174cm, 70kg):
Low activity, such as office work: approximately 2,000~2,200kcal
Moderate activity level, exercising 3
4 times a week: approximately **2,4002,600kcal**Active activity level, exercising 5
6 times a week: approximately **2,8003,000kcal**
For adult women (based on those in their 30~49s, 161cm, 57kg):
Inactive state with low activity: approximately 1,600~1,800kcal
Moderate activity level, exercising 3
4 times a week: approximately **1,9002,100kcal**Active activity level, exercising 5
6 times a week: approximately **2,2002,400kcal**
As you can see, the energy required varies greatly depending on the amount of activity. If someone with low usual exercise volume eats as much as the general recommended calories, weight gain is inevitable.
Calories That Are Exceeded Before You Know It While Eating Deliciously
The problem is that the 'delicious foods' we enjoy often have much higher calories than we think. When reviewing food diaries in the consultation room, many patients think they ate a little, but in reality, they far exceeded the daily recommended amount even by eating small portions of high-calorie foods.
In particular, meals centered on greasy foods or refined carbohydrates are very high in calories relative to their volume. No matter how hard you exercise, if the calories you eat exceed the amount consumed, weight loss will stall. Therefore, for weight loss, rather than vague willpower, a strategy is needed to accurately know what and how much you are actually eating and to limit intake.
A Traditional Korean Medicine Perspective on Increasing Metabolic Efficiency
In Traditional Korean Medicine, we do not look only at the number of calories. Even if you eat the same calories, we focus on the difference in metabolic efficiency—whether you burn them well as energy or store them as they are in the body.
Some people are in a state of Gi-heo (energy deficiency), meaning their BMR itself is low, so they bloat and gain weight even if they eat a little; others have Dam-seup (phlegm-dampness), which are waste products in the body that block energy circulation. A diet that only matches calorie numbers while ignoring these constitutional characteristics is bound to be exhausting and has a high probability of the yo-yo effect. That is why I encourage patients to first identify their own constitution and current metabolic state.
Tips for Reducing Calories to Practice Starting Today
Then, how can you efficiently reduce calories in daily life? I will point out a few practice points I frequently recommend in the consultation room.
First, try adjusting the amount of food itself. If you reduce it drastically all at once, you may binge eat due to a compensation mentality, so it is good to start by removing about 1/4 of your usual meal portion.
'Substitution strategies' to change the types of food are also effective.
When eating meat, try choosing chicken or duck instead of greasy pork belly. In particular, grilled chicken breast helps maintain muscle while reducing calories, as it is rich in selenium, vitamin B6, and folate.
When you crave bread, try whole grain bread, even if it is a bit coarser than white bread. The rise in blood sugar is slowed, and the feeling of fullness lasts longer.
The best method is to plan a diet centered on vegetables to keep the volume the same while lowering the overall calorie density.
Please remember that when small changes in habits accumulate, metabolic capacity changes, and that leads to a healthy body shape.
Rather than becoming obsessed with numbers and getting stressed, the process of slowly adjusting while listening to the signals your body sends is important. Too strict limitations can actually be poisonous, so please approach it healthily according to your own condition.
If controlling your diet and managing weight alone feels overwhelming, try the Baekrok Gambi-jung tablet program. If you manage your metabolism according to your constitution, you will be able to reach your goal much more easily.
