In order to achieve your goal weight, you must adjust your daily nutrition habits to the defined goal. Choose food with higher content of calories to increase your calories intake. Remember that your diet should be healthy, so abstain from fast food.
I found great recommendation about the amount of proteins, carbohydrates, and lipids, fats, fiber, and cholesterol that you need to consume daily in Diet Tracker, Weight Gain app. Body Mass Index and the percentage of Body Fat are also calculated based on your gender, age, height and current weight. It also gives you useful tips on how to gain weight. The tips include such recommendations as to train your body every day and not to drink water before eating and while eating your meal.
