Pumpernickel and rye-based breads, along with jam, margarine, honey, or even butter, may be suggested for gaining the desired number of calories. Choosing the right kind of cereals, also influences the objective of weight gain. For example, choosing granola instead of corn is always advisable. Eating fruits like bananas, dried fruits, dates, mangoes, and pineapple will prove to be better than fruits such as apples and grapes which have a high water content.
