What Should Elderly Eat To Gain Weight?

Consume smaller meals on a more frequent basis. At every meal and snack, choose meals that are rich in calories and high in protein.
Choose from a variety of foods such as eggs, beef, poultry, fish, and nut butters.
Improve the nutritional value of your regular foods by including healthy fats or oils, such as pouring olive oil on your steaming veggies or mixing non-hydrogenated margarine into your brown rice.
