Just in case you aren't sure what the keto diet entails, here's a quick refresher. According to keto experts, your macronutrient profile on the keto diet should be 70 to 80 percent fat, 15 to 20 percent protein, and five to 10 percent carbohydrates per day. In order to find out if you're in a state of nutritional ketosis — where your body is using fat instead of glucose (sugar/carbohydrates) as a source of fuel — you'll need to urinate on a stick or do a blood test; not fun, but they're the most accurate.
You may experience symptoms like dehydration, catch a case of the keto flu during the initial weeks, or possibly end up with vitamin and mineral deficiencies while following the keto diet.
