How to increase calories?

Adding more fat to diet will increase calories without adding bulk.

Remember that fat has 9 calories per gram, while protein and carbohydrates have 4 calories per gram.

• Emphasize vegetable oils such as flaxseed or canola and cold water fish that supply high levels of the essential fatty acids (omega-3 and omega- 6). 
• Avoid or reduce the use of foods with hydrogenated or partially hydrogenated oils that create trans-fatty acids that interfere with the body`s ability to utilize the essential fatty acids.
• Add butter or oil to meats, vegetables, hot cereals, and cooked desserts.
• Mayonnaise, sour cream, and salad dressings can be served on vegetables, meats, sandwiches, and fruit salads.
• Include peanut butter and other nut butters that are high in oil.
• Cream and ice cream have a high fat content.
• Add heavy cream to puddings.
• Mix fruit- sweetened ketchup or yogurt with 1 to 3 teaspoons of flax oil to get rid of the oily taste and make it more palatable to children.
• Avocados are high in fat and calories. They are excellent for softer diets.
