In one sentence, describe what the following article is about:

Try to avoid acidic fruits like citrus as this will give you stomach pains, stick to watery things, e.g. melon, watermelon, cucumber. Add some milk and oats, but go very easy on the oats. Depending on the length of your fast, you cannot handle too much food.
Make a fruit and/or veg smoothie on the first day. Drink more home made smoothies on the second day, and try some light soup. Start eating solids again on day three; stick to fruits and vegetables. Continue with the fruit and veg, gradually eating more and more in one day. Eat some dry toast and a bowl of oatmeal with raisins and nuts when you feel ready to reintroduce them. Reintroduce the rest of your everyday foods slowly- in reverse of how you prepared works fairly well. Visit a doctor for a quick checkup when you are eating normally again, just to make sure you haven't damaged yourself.
