The Wild Diet can be considered a lower carbohydrate diet. It is restrictive in grain intake with a less emphasis on fruits as well.
The Wild Diet is similar to the paleo diet. The research of long term health benefits from following a paleo diet is lacking (4).
Therefore the long term benefits of restricting fruits and whole grains while eating a higher amount of saturated fats is not clearly known.
It may not be beneficial to eat as much red meat as you want. Several health organizations recommend limiting red meat, especially processed red meat.
The Wild Diet can be a healthy guideline for eating, but it is not the only healthy way to eat. Parts of the Wild Diet are very healthy such as: eating a high intake of vegetables and following intuitive eating.
However, limiting intake of whole grains and limiting fruits may not be beneficial for everyone.
Following diets that are paleo based currently lack evidence of long term health benefits.
However limiting processed foods while eating more fruits and vegetables as the Wild Diet suggests can be a healthy recommendation for everyone.
