You might consider reading material on fasting as you come into this time. If you choose a ‘Daniel fast’ then you would avoid sugars, desserts and meats. If you choose a ‘liquid fast with supplements’, then you maybe once a day you would make a fruit smoothie with tofu or soy protein added to the drink. You can buy these products in powder. You might want to avoid high sugar instant drinks. Tofu blended with fruit makes a delicious and healthy drink. You can use banana, apples, frozen strawberries, frozen blueberries, etc. Frozen berries can be purchased at the grocery store.
