Remembering to count calories takes a little adjustment, but doing so can be the difference between optimal physical health and the multitude of health risks that come with being overweight. The number of calories that men should consume daily fluctuates according to multiple factors, such as a man's age and how active a lifestyle he leads.
Although a male's recommended caloric intake increases through his adolescent years, it begins to slowly decline through adulthood. A man between the ages of 19 and 30 should consume 3,000 calories per day if he's active, between 2,600 and 2,800 calories per day if he's somewhat active and between 2,400 and 2,600 calories per day if he's sedentary.
From 31 to 50 years of age, an active man should consume 2,800 to 3,000 calories per day, a moderately active man should aim for 2,400 to 2,600 calories per day and an inactive man should get 2,200 to 2,400 calories per day.
Over the age of 51, men should consume 2,400 to 2,800 calories per day if they're active, 2,200 to 2,400 calories per day if they're somewhat active and 2,000 to 2,200 calories per day if they're not active.
To maintain weight, the calories eaten should match the calories used to maintain metabolism and to fuel physical activity. To lose about a pound a week, you need to achieve a deficit of 500 calories per day by eating less, exercising more or doing both.
