Stimulate your appetite: When you don’t feel like eating but still want to gain weight you have to work with your appetite. A bit of light exercise before your meal will get your appetite going. If you really don’t feel hungry eating one of your favourite comfort foods may work. Chewing gum gets your digestive system flowing which in turn will make you feel to eat so that is a good trick too.
Muscle Mass: Muscle holds a higher mass than fat. Also, if you are gaining weight you will want to exercise to ensure the weight goes to the right places, you still want to look fit. Have a protein shake and an energy after working out to re-fuel your body and get good calories on.
Eat smart: In order to gain weight you will want to increase the fat intake in your diet. The best kind of fats for your body are plant fats. For example- avocados, seeds, nuts, peanut butter and potatoes. These foods are nutrient and calorie rich which is exactly what you want when trying to gain weight healthily. Animal fats also hold nutrients but they contain saturated fat which is bad for your cholesterol. Pick up small habits that will help you pack on the calories. For example, sprinkle nuts over your salads and have high calorie condiments such as mayonnaise.
