Your body isnt used to the sugary food after you eat healthy for a certain amount of time
In other words, its very normal
Yup, because processed sugar isn't meant for human consumption. When you go on a body cleanse you will find that a lot of things will make you ill - fast food, anything in a box loaded with table salt and preservatives - fun fact, my buddy set a McDonald's and Wendy's burger and fries out on his counter for 3 years, that's right, it actually survived for that long out in open air - no mold on any of it, and it still looks like he just bought it. Imagine what that crap does to your insides...
