Add calories to your daily diet by eating more frequently, choosing more calorie-rich foods, having snacks in addition to meals, eating desserts with some positive nutritional properties and drinking smoothies,
milk or juice with meals during the day instead of water. Make nutritionally sound choices from the core food groups, including low-fat dairy, lean protein, fruits, vegetables and whole grains, but don’t shy away from calorie-dense options that are also full of nutrients.
