- Choose what you drink: Avoid drinking zero calorie drinks such as sodas, soft drinks, tea or coffee. Go for nutritious drinks such as Fruit juices, Milk shakes, Vegetable soups, Chicken soups, Boiled meat broth, Casseroles etc.
- Have Sweets and Chocolates: Eating a chocolate bar everyday would add in extra calories to your diet. Go for nut chocolates as they provide more calories than the usual chocolate bars. Eat sweets such as muffins, deserts, fruit pies, which provide a lot of calories.
- Do the right exercise: Blindly doing exercise would not help you gain weight.

Instead go for resistance exercises such as weight lifting where you can actually build muscle mass and have adequate weight gain.
