If you have a feeling of constant tiredness, which feels worse with exercise and doesn’t improve with sleep, you may have what Dr. Berg calls chronic fatigue syndrome.

The best way to address the underlying causes of chronic fatigue syndrome (along with a host of other health issues) is by taking a ketogenic approach to the fuel you put into your body.

A lot of people are interested in keto because it sounds rational and achievable. (Hint: it is!) But many people aren’t sure how to get started in a way that is going to last. Check out the 28-Day Keto Challenge, which sets you up with an easy-to-follow plan that will set you up for success with keto.
