A balanced 1,500-calorie diet includes a 400-calorie breakfast and lunch, a 600-calorie dinner and healthy snacks, such as fruit, yogurt, air-popped popcorn, muffin or hard-boiled egg. A 1,500-calorie per day diet is a balanced and controlled eating plan with moderate fat and calorie intake, notes Brigham and Women's Hospital.
The number of calories a person should eat to lose or maintain weight depends on the person's gender, general health and age, notes WebMD. A calorie intake of less than 1,800 calories is a sustainable diet for weight loss. A sample menu would include: 1 cup of cereal with 1/2 cup of fat-free milk and half a banana for breakfast; 3 ounces of tuna, chicken or veggie burger on whole-wheat bread with a salad or vegetables for lunch; 3 ounces of grilled chicken or sirloin, 1/2 to 1 cup of vegetables, 1/2 cup brown rice or small potato with a small side salad and low-fat vinaigrette for dinner.
