For my first tip I am going for the nutritionist favourite.
Kim Tip - Warm Lemon Water
In the morning on an empty stomach. Squeeze fresh lemon into room temperature water when you first wake and drink it up. Your liver should be detoxing during your sleep so when you wake up you want to help flush toxins out. You do not what them to re-absorbed, plus it helps give your metabolism a little boost and lemons have many nutrients including Vitamin C.
Enjoy and give your liver a hug!
