Important Factors

• If you are thin due to lack of nourishment from poor appetite or an eating disorder, it is important to start slow and work your way up. You should also work with a dietician because he or she can set up a specific meal plan for your needs. Counseling may also be needed for a full recovery.
  
  

Protein Shakes

• The human body needs protein for optimal health. Protein is what your hair, skin and other cells are made up of. Protein shakes can also help a lean person gain weight when they are consumed in addition to a meal. Buy protein powder at your local health-food store and combine a banana and other fruit in a blender. When people are trying to lose weight, they will consume a protein shake in place of a meal.
  
  

Pasta

• The right type of whole-grain pasta is actually a healthy food. Pasta contains carbohydrates. People who eat a lot of pasta are generally heavier. This is a good food for weight gain because it is healthy. After you achieve your desired weight, it is important to cut back on pasta or you may continue to gain more weight than what is desired.
  
  

Milk

• Raw organic whole milk is loaded with vitamins and minerals such as calcium. Drinking raw organic milk will provide your body with healthy bacteria that can be beneficial for your digestive health. Healthy bacteria are also known as flora. These good bugs help to improve immune function and overall health. The fat content found in raw whole milk will help you to gain weight when it is consumed daily.
  
  

Nuts

• Other healthy foods that can pack on the pounds are nuts. They are filled with healthy omega-3 fats that are also good for your heart and brain. Pine nuts, almonds, and peanuts are loaded with protein and other nutrients. Snack on nuts throughout the day for extra energy, and you will gain weight over time.
