The ketogenic, or keto, diet can sometimes sound too good to be true, though many people swear by it. The basic idea is to eat more fats and fewer carbs to move your body into a state known as ketosis, during which your body converts fat into compounds known as ketones and begins using them as its main source of energy.

The challenge in following a keto diet often comes in finding the proper balance of foods. But the right technology can make all the difference.
