1. Basal Metabolic Rate (BMR) and Daily Caloric Intake Goals For a 46-year-old male, calculate the Basal Metabolic Rate (BMR) and set an appropriate daily caloric intake. Generally, to lose 1 kg of weight, about 7,700 kcal needs to be reduced. To lose 20 kg, a total of 154,000 kcal must be reduced, with the goal being an average reduction of about 1,711 kcal per day.
2. Diet Plan Aim to limit daily caloric intake to about 1,500 to 1,800 kcal for weight loss. Each meal should primarily consist of proteins and vegetables, including a balanced amount of complex carbohydrates and healthy fats. Ingredients for each meal will be kept simple, using no more than three main components.
3. Exercise Plan The plan includes exercising at least 5 times per week, with a minimum of 30 minutes of moderate-intensity exercise each day. This will include a variety of aerobic exercises such as jogging, cycling, swimming, along with strength training to maintain muscle mass and boost metabolism. Abdominal exercises will also be included to reduce belly fat.
