9 celebrities who love the keto diet

The keto diet is not for the faint of heart.

The diet has gained major traction in the wellness world and is lauded by everyone from athletes to actresses for its reported health benefits, including weight loss, lower blood sugar and lower blood pressure. By following the strict low-carb, high-fat diet, your body will enter ketosis, the metabolic state that burns fat instead of carbs.

While the diet isn't for everyone and has caused a fair share of controversy amongst health professionals and trainers -- Al Roker recently got into a tiff with trainer Jillian Michaels about its benefits -- high profile names such as Halle Berry and Tim Tebow have relied on the keto diet to whip them into shape.
