7. Short-Term Fatigue
The initial switch to a ketogenic diet can be one of the biggest issues for new dieters. Its well-known side effects can include weakness and fatigue.
These often cause people to quit the diet before they get into full ketosis and reap many of the long-term benefits.
These side effects are natural. After several decades of running on a carb-heavy fuel system, your body is forced to adapt to a different system.
As you might expect, this switch does not occur overnight. It normally requires 7–30 days before you are in full ketosis.
To reduce fatigue during this switch, you may want to take electrolyte supplements.
Electrolytes are often lost because of the rapid reduction in your body’s water content and the elimination of processed foods that may contain added salt.
When adding these supplements, try to obtain 2,000–4,000 mg of sodium, 1,000 mg of potassium and 300 mg of magnesium per day.
Bottom Line: Initially, you may suffer from tiredness and low energy. This will pass once your body becomes adapted to running on fat and ketones.
