Everyone’s obsessed with keto these days, and for good reason. The keto diet (short for ketogenic) is a low-carb, high-fat eating plan that turns your body into a fat-burning machine. By depriving the body of glucose, from carbs, it forces you to burn fat for energy instead. Science shows a ketogenic diet:


  • Controls your hunger hormones. If you’re not hungry and distracted, you eat less without trying, so you burn fat fast.
  • Boosts energy. On a keto diet, your liver converts fat into ketones -- your body’s preferred energy source. When you’re in ketosis, you have a steady supply of them in your bloodstream. That means no sudden energy crashes, brain fog, or grumpy moods like you get when your body runs out of carbs to burn.
  • Increases mental focus. Your brain is 60% fat, so you need to feed it plenty of healthy fats to stay sharp. Plus, keeping carbs low helps your body produce ketones, which provides clean fuel for your brain cells.


Cyclical keto involves eating an extra serving of carbs one day per week to keep your metabolism humming and to prevent common problems that come with long-term keto, like dry eyes, hormonal imbalances and fatigue.
