- Women who are underweight during pregnancy tend to eat low-calorie foods and not enough protein. The following are ways to get more calories:
- Eat breakfast every day. Peanut butter or a slice of cheese on toast can give you an extra protein boost.
- Snack between meals; yogurt and dried fruits can provide protein, calcium, and minerals.
- Try to eat more foods that are high in good fats such as nuts, fatty fish, avocados, and olive oil.
- Drink juices that are high in vitamin C or beta carotene, such as grapefruit juice, orange juice, papaya nectar, apricot nectar, and carrot juice.
- Avoid junk food
- Consult your health care provider about taking prenatal vitamins
