For thousands of North Americans, the keto diet has proved to be one of the fastest and most effective ways to lose weight and develop a healthier lifestyle. 

By focussing on dramatically reducing carbs, the keto diet puts the body into a state called ketosis, in which its primary source of fuel becomes fat rather than carbohydrates and sugars. This, in turn, leads to rapid but healthy weight loss, and many keto eaters also claim to have more energy and a greater ability to focus. 

Eating keto is all about finding good, healthy sources of fat, however, and for people just starting this diet for the first time, this can be a bit of a challenge. The North American diet tends to be very carb heavy, and while increasing fat intake may sound easy, in practice it takes a lot of careful calculation.
