How to Choose a Diet Book

If you're looking to switch up your diet, the first thing you should ask yourself is why. Should Runners Take Vitamin D in Winter?

Second, consider your lifestyle. Do you need meals that are quick and easy? Do you like to take an hour or two to cook for yourself every night? How often can you grocery shop for fresh ingredients?

Finally, consider whether you're looking specifically for a cookbook or one that will provide you education on a particular way of eating without necessarily giving you recipes. While many cookbooks will have some content that discusses the origins of food and their nutritional benefits, these books are unlikely to go as in-depth regarding nutrition as less recipe-focused ones.
