I already enjoyed Martina's website and several other keto/lowcarb recipe blogs so decided to support her and purchase the book. I'm familiar with this style of cooking and have most of the required ingredients in my pantry already so I was able to dive in and cook straight away, delicious dinner last night of tuna zoodle ‘pasta’ bake. If you have yet to try low carb cooking I recommend trying out a few recipes from the web before purchasing a cookbook, get a feel for what is involved. I look forward to making many more recipes from the book, love the simple layout, nice clear instructions and front of book info on keto lifestyle and cooking. Smaller size and not too chunky which I like also. Very good cookbook at a good price
