If you're starting the 5:2 diet or looking for more inspiration, cookbooks are a great place to get plenty of ideas particularly when it comes to reaching 500 calories a day.

"The 5:2 diet is essentially a calorie limited diet which follows a prescriptive programme based on days of the week. Essentially, the basic rules go something like this: for two days a week, if you are a female, eat just 500 calories, or 600 if you are a man. These foods can be consumed at any time of the day and consist of any food you like. Then, for the remainder of the week, eat and drink as you would normally," says Clinical Nutritionist, Mike Wakeman from the evidence-backed personalised nutrition service Vitamedics.

Cookbooks in this roundup include the sought-after Pinch of Nom Everyday Light cookbook, The 5:2 Diet Cookbook, and The Simple 5 Ingredient Skinny Slow Cooker Recipe Book to name a few. The majority are available to buy online on Amazon - most with free delivery and some with free Kindle Editions too. 

These cookbooks aren't just full of recipes either, they also include top tips and tricks to help you along the way as well as guides and explanations on how the 5:2 diet works and what rules apply.
