Contraindications
When considering the paleo and keto diets, it is essential to be aware of certain contraindications. These diets may not be suitable for individuals with specific health issues or conditions.
The keto diet should be avoided by individuals with existing kidney or heart disease, as well as those with type 1 diabetes or conditions affecting the pancreas, gallbladder, or liver. The restrictions and demands of the diet may be unsafe for these individuals.
On the other hand, the paleo diet naturally lacks sufficient vitamin D and calcium compared to a traditional diet. Therefore, individuals at risk for osteoporosis should ensure they are obtaining these essential nutrients from other sources if they decide to follow this diet.
Individuals with kidney conditions should consult their doctors before significantly increasing their protein intake, as both the paleo and keto diets emphasize higher protein consumption. It is crucial to ensure that these individuals do not exacerbate their kidney condition unintentionally.
Similarly, individuals with type 2 diabetes should seek guidance from a physician before severely restricting carbohydrates. Both the paleo and keto diets involve limiting carbohydrate intake, and it is vital to manage blood sugar levels effectively in individuals with diabetes.
It is generally advisable to consult with a doctor or nutritionist before making significant changes to one’s diet. These professionals can provide guidance to ensure that necessary nutrients are being consumed, even with dietary restrictions or modifications.
Side Effects of Ketogenic and Paleo Diets
When adopting a low-carbohydrate diet that induces ketosis, individuals may experience a range of side effects commonly referred to as the “keto flu.” These side effects can include feelings of fatigue, general illness, headaches, muscle pain, and even episodes of nausea or vomiting. It is important to note that these symptoms are not caused by a viral infection but rather by the body adjusting to efficiently utilizing fat as its primary fuel source. Typically, the keto flu subsides within a few days; however, an enduring indication of ketosis is the persistence of bad breath.
Similar to the ketogenic diet, the paleo diet can also trigger flu-like symptoms. Additionally, individuals following the paleo diet may experience constipation or diarrhea. To alleviate these digestive discomforts and maintain digestive health, it is advisable to consume ample amounts of fiber-rich, paleo-approved foods.
