On page 54 of Carb Back-Loading, we are warned that eggs can spike insulin levels, and a footnote to the following study is given: http://ajcn.nutrition.org/content/66/5/1264.full.pdfHowever, this study seems to indicate that eggs produced a smaller insulin response than any other food they tested aside from peanuts. Beef and fish were among the protein sources that have a higher insulin index than eggs, and those foods are CBL staples. What is the reasoning behind the suggestion that eggs spike insulin?
