Micronutrients & recovery
The 'keto flu' (flu-like symptoms during initial adaptation) can be avoided or alleviated by increasing sodium and mineral intake.
If you feel tired or have headaches when starting a low-carb diet, drink two cups of broth daily to replenish sodium and minerals. This simple step can prevent or alleviate the 'keto flu'.
GoodSupportsHIGH confidence
These symptoms are usually due to the excretion of sodium in the urine and the consequent diuretic effect of carbohydrate restriction that manifests when blood volume is decreased (hypovolemia). The condition can easily be alleviated or avoided simply by drinking two cups of soup broth daily (even soup derived from a bouillon cube) or obtaining other sources of sodium and essential minerals.
Why this rating
Based on the authors' clinical experience and cited literature on managing keto-induction symptoms.
