- Drink lots of warm water and ginger tea throughout the day and with meals. A very warm cup of water in the morning can help cleanse your body by flushing out toxins. Warm water will help break down these foods even faster, making them easier for you to digest. Drinking cold water during or after a meal can actually harden the oil in consumed foods and therefore create a fat deposit in the intestine. Luckily, you can replace a glass of cold water with a warm one to aid digestion, especially after eating a meal.
