How many calories do you need to consume per day to lose weight

The daily calorie consumption during weight loss varies from person to person, and it is usually recommended to create a calorie gap of 500-1000 calories. The daily total energy expenditure of adults is composed of three parts: basal metabolic rate, food heat effect, and physical activity expenditure. The basal metabolic rate accounts for the majority of total consumption, about 60-70%, referring to the minimum energy required to sustain life in a resting state. The thermal efficiency of food should account for about 10%, which is the energy consumed during the process of digesting and absorbing food. The proportion of physical activity consumption varies greatly, with light laborers accounting for about 20-30% and heavy laborers accounting for over 40%. Creating a calorie deficit is mainly achieved by increasing activity and reducing intake. Adding activities can choose to consume 150-200 calories per hour for brisk walking, 400-500 calories per hour for swimming, and 600-800 calories per hour for high-intensity interval training. To reduce intake, it is necessary to avoid high sugar and high-fat foods, such as 100 grams of fried foods containing 500-600 calories, while the same amount of boiled vegetables is only about 50 calories. Monitoring weight changes and body fat percentage can evaluate effectiveness, and losing 0.5 kilograms per week is safer. During the weight loss process, it is necessary to maintain a balanced diet, with a daily intake of no less than 1200 calories, to avoid excessive dieting that can lead to a decrease in basal metabolic rate. Suggest replacing the main course of three meals with coarse grains such as oats and brown rice, and increasing the intake of high-quality protein such as chicken breast and fish. Choose steaming or boiling instead of frying for cooking, and drink 2000 milliliters of water daily to promote metabolism. Combining aerobic exercise 3-5 times a week for more than 30 minutes each time is more effective, and supplementing protein appropriately after exercise can help maintain muscle mass. If discomfort symptoms such as dizziness and fatigue occur, adjust your weight loss plan and consult a professional nutritionist or doctor if necessary.
