How many calories does a person normally burn in a day

The normal daily calorie consumption of a person is generally between 1500-2500 kcal, and the specific value is related to factors such as gender, age, weight, and activity level.

Adult women consume approximately 1200-1500 kcal per day in their resting state, and if they engage in light physical activities such as office work, the total consumption can reach 1800-2200 kcal. The basal metabolism of adult males is usually 1500-1800 kcal, and the total consumption under the same activity intensity is about 2000-2500 kcal. Teenagers may consume 10% -20% more per day than adults due to their growth and development needs. Individuals with higher body weight have more muscle tissue and a relatively higher basal metabolic rate. Daily activities such as walking for 30 minutes can consume an additional 100-150 calories, while high-intensity exercise such as running for 1 hour may increase calorie consumption by 400-600 calories. The process of dietary digestion and absorption also consumes energy, accounting for about 10% of the total calories in food.

It is recommended to maintain energy balance through a balanced diet and regular exercise, and avoid long-term intake exceeding expenditure leading to obesity. You can choose staple foods such as oats and whole wheat bread that are rich in dietary fiber, and pair them with low-fat and high protein foods such as broccoli and chicken breast. Regularly monitor the change of body weight. In case of sudden increase or decrease of body weight for unknown reasons, seek medical advice in time to check metabolic diseases such as thyroid dysfunction and diabetes.
