I decided to try going veg, have my frig stocked with everything from soymilk to tahini and began cooking on Saturday. Prior to Saturday and since about 9/6 I have been following the SBD, most meat was chicken and fish with occasional red meat. Anyway, since Friday I have had a headache off and on. I try to spread my food out throughout the day, eating about every 2-3 hours and according to Nutrition MD.org, I'm getting in around 1100 calories on average.
Is there such a thing as protein withdrawal? Or are my headaches more likely due to something else besides my new eating habits.
