How many calories can be burned daily to lose weight

Losing weight requires creating a daily calorie deficit. Women are advised to limit their total daily calorie intake to 1200-1500 calories, while men should limit their intake to 1500-1800 calories. The calorie deficit can be achieved through a combination of dietary control and exercise, with a recommended deficit value of 300-500 calories. The calorie expenditure is closely related to an individual's basal metabolic rate and activity intensity. Basic metabolism accounts for about 60-70% of daily total consumption, and the daily total consumption of mildly active individuals (such as sedentary office workers) is about 1600-1800 kcal for females and 1800-2200 kcal for males; Moderate activity intensity (such as walking 8000 steps per day) can reach 1800-2100 calories for women and 2100-2400 calories for men. On this basis, reducing dietary intake by 300-500 calories or increasing equivalent calorie expenditure through exercise can achieve safe weight loss. Food choices should mainly focus on high protein, high dietary fiber, and low glycemic index, such as chicken breast, broccoli, oats, etc., avoiding refined sugar and saturated fat. We recommend moderate to low-intensity aerobic exercises such as brisk walking and swimming, combined with 2-3 resistance training sessions per week to maintain muscle mass. During weight loss, it is necessary to ensure a daily protein intake of no less than 1 gram per kilogram of body weight to avoid excessive dieting and muscle loss. Long term calorie deficit exceeding 500 kcal may lead to problems such as decreased basal metabolism and malnutrition. It is recommended to control the weight loss rate at 0.5-1 kg per week and regularly monitor changes in body fat percentage. If symptoms such as fatigue and dizziness occur, adjust your diet plan in a timely manner and consult a nutritionist if necessary to develop a personalized plan.
