Gaining weight is reduced to two things, training and nutrition. Of the two, nutrition is the most important. Unfortunately, skinny boys often have trouble consuming enough calories per day to pack on mass as fast as they want. If this is the problem you then use to load these quick snacks on the quality of calories.

1. Trail Mix

Trail mix can be made with a variety of ingredients, but overall it is a mixture of nuts and dried fruits. Nuts provide most of the calories here with a good healthy dose of fat and a small amount of protein. Nuts provide some extra calories, plus the antioxidants in things like raisins and dried cranberries.

2. Nut butters

Peanut butter is a staple food, but you can also try almond butter, cashew butter, and macadamia nuts. All these provide a huge boost from calorie healthy high-fat, along with some protein and fiber. Just be sure to get the “natural” versions that contain no added sugar or fat.

3. Milk

Whether as a whole, 2%, skim, or chocolate, milk is good way to not only increase your calories, but also its protein. Milk protein is about 80% of whey protein and 20% protein casein, the same combination as seen on many faces of protein powder. But besides the protein you also get plenty of carbohydrates and fat. Wash down your next meal with a glass of milk to help you pack on the calories.

Note that these snacks are for those of you who are having trouble gaining weight. But even those who find themselves in this situation it is necessary to carefully monitor your body fat percentage. The goal is always to gain muscle and minimize fat. Do not use weight gain as an excuse to get fat!
