Preliminary steps
Firstly, eliminate all the causes of underweight. Make sure that you do not suffer from underlying illnesses that cause weight loss or hamper weight gain and that other important factors such as medications, depression, or anxiety are not preventing you from gaining weight.
If you have a clean bill of physical and mental health, the solution to underweight is to ingest more energy on a daily basis than you use up for physiological processes and physical activity.
This means that you must eat more at each meal and have healthy snacks between meals. If necessary, take a meal supplement like Ensure or Fresubin with fibre or one of the Nestle products such as Nutren Fibre between meals every day.

Tips for making smoothies
To make delicious smoothies, use the following:
1-2 fruits (peeled apples or mashed bananas, mixed with 1 T of lemon juice to prevent fruit from discolouring, or apricots, mangoes or fresh berries, or any other fruit in season)
1 cup of full-cream milk
2 T whole-milk powder
2 t sugar or honey
Place ingredients in blender. Blend till smooth and serve ice cold.
My favourite smoothie:
1 ripe avocado (peel, remove pip and mash with 1 T lemon juice to prevent discolouration)
1 cup of full-cream milk
2 t honey
Place ingredients in blender. Blend till smooth, chill till ice cold and serve with a pinch of nutmeg on top.
