The whole idea of going on a paleo diet is based on eating like our ancestors ate. In simpler words, eat like a caveman. When on a paleo diet, you cut out on a ton of processed foods and go on a higher protein to carb ratio diet that can aide in the process of weight loss. Paleo dieting is a good way to move to a more wholefoods approach by eliminating processed junk food and sugar. However, there are certain side effects that you should be aware of before going on a paleo diet.
