13 best keto diet books for beginners and beyond

If it seems like everyone is talking about the ketogenic diet these days, you're not wrong. Celebrities like Halle Berry, Kourtney Kardashian and even Al Roker have jumped on the bandwagon and toted their success with the fad. However, the strict high-fat, low-carb diet is definitely not for everyone.

Eating a ketogenic diet will put your body into a metabolic state of ketosis, which is when your body uses fat instead of carbs for fuel. Yes, this means that your body will be constantly burning fat, whether you're exercising or sitting on the couch watching Netflix. But, it's definitely not easy to get to this state.

To do so, you'll need to eat foods that are high in fat and low in carbs, even if that means omitting certain types of fruit and vegetables. Depending on your body, it can take one to three days to get your body into ketosis and with any big change, it will take some getting used to. You may experience what people call the "keto flu," which can include headaches, nausea, fatigue, stomach aches and mood swings.

Once you're in ketosis, you'll need to stick to the diet pretty much 100 percent of the time. Eating too many carbs (even a sip of soda!) can take your body out of ketosis and you'll have to start all over again. Surely, that doesn't sound like a big deal, but it can take your body sometimes a few days to get back into the fat-burning zone and you could experience that keto flu again.

So, if you're thinking about going keto, there are a obviously few things you should keep in mind before stocking up your cart with bacon, avocados and other keto snacks. Below, we've rounded up a few books to explain the nitty gritty details and help you get started. If you're already a few weeks into the diet and looking for some meal inspiration, we've got that, too.
