Is the Keto Diet Safe?

Low blood pressure, kidney stones, constipation, vitamin shortages, and an increased risk of heart disease may result from the keto diet. Strict diets, such as keto, may also result in social isolation or disordered eating. Keto is not recommended for people who have pancreas, liver, thyroid, or gallbladder problems.

According to Kleinman, someone new to the keto diet may suffer "keto flu," which includes symptoms such as upset stomach, dizziness, low energy, and mood fluctuations caused by your body transitioning to ketosis.
