The first signs of ketosis are known as the “keto flu” where headaches, brain fogginess, fatigue, and the like can really rile your body up. Make sure that you’re drinking plenty of waterand eating plenty of salt. The ketogenic diet is a natural diuretic and you’ll be peeing more than normal. Take into account that you’re peeing out electrolytes, and you can guess that you’ll be having a thumping headache in no time. Keeping your salt intake and water intake high enough is very important, allowing your body to re-hydrate and re-supply your electrolytes. Doing this will help with the headaches, if not get rid of them completely.
"Plenty of people jump right in, thinking all they have to do is cut carbs and increase fat. All of a sudden, they hit a wall and get 'keto flu.' They feel tired, lethargic, and experience headaches," Wittrock says. "The primary reason they get these symptoms is lack of the three primary electrolytes: sodium, potassium, and magnesium. If you're deficient in any of these, you'll suffer mentally and physically. This is the single biggest reason people fail on the keto diet."

Makakatulong din ang nutrisyon. Ang hindi kumakain ng mabigat na pagkain bago ang kama ay maaaring isa sa mga pinakamalaking bagay na maaari mong gawin para sa isang matulog na may kalidad na gabi. Ang alkohol, bagaman maaari mong isipin na nakatutulong ka na makatulog, ay talagang isang pagtulog sa pagtulog, kaya limitahan ang iyong paggamit. Dapat ding iwasan ng kapeina ang hindi bababa sa 4 oras bago ang oras ng pagtulog.
