Underweight? See how to add pounds healthfully - Drugs.com
Although being lean can often be healthy, being underweight can be a concern if it's the result of poor nutrition or if you are pregnant or have other health concerns. So, if you're underweight, see your doctor or dietitian for an evaluation. Together, you can plan how to meet your goal weight.
Try smoothies and shakes. Don't fill up on diet soda, coffee and other drinks with few calories and little nutritional value. Instead, drink smoothies or healthy shakes made with milk and fresh or frozen fruit, and sprinkle in some ground flaxseed. In some cases, a liquid meal replacement may be recommended.
